Great idea: low watt usage.  Fark: will never last the warranty period, but long enough for you to lose the receipt. TotalFark: 60w bulb doesn't provide enough light to read by.

I've got some of the Philips bulbs, the ones that have yellow plastic on the top. Their 60W bulb uses 12.5W, and does put out as much light as a real 60W bulb. They turn on instantly, and the color is perfect. My wife hates anything but incandescent, yada yade, but I slipped one of these into the living room reading light about 6 months ago and she has not noticed heh. They are $20 each though. I'll definitely have to try some of these new ones, have not had one fail yet so I would not be surprised if they make 10 years and on.

I've yet to have any early failures in my apartment full of LEDs (90% of which are Phillips), and Cree makes some of the best LEDs out there, so I'm looking forward to this

I'm curious as to whether they work with X10 and other home automation systems. The only LED bulb I've seen work with the X10 socket rocket is the ECS bulb mentioned in the article.

Well I wouldn't suggest that you go out and replace your existing lights right away, these kind of things are more for when it comes time to replace your existing lights. And at the current rate of improvement, there might even be an appropriate brightness for you at that time. One bit of advice I do have though, if you are using 5000k + lamps, pay lots of attention to the CRI rating

it's not photography critical so it doesn't matter too much. 5000k-6000k is going to look better period, CRI inside that band is just which bulb is better in band.

If you skimp on CRI, you'll find that some colours will just be shiat and muted. LEDs with a poor CRI will typically mute reds quite a fair bit, for example. Most people like their light sources to properly portray colours. It may not be important to you, but that doesn't mean that it isn't important to others

We've been conditioned to expect warm lighting in the evenings for thousands of years. That kind of daylight-ish white light is just weird at night. My bedroom uses the daylight-style bulbs and my living room uses more yellowish bulbs and my bedroom is way less inviting a place than my living room, probably explaining my lack of success with the ladies.

Weird. I definitely prefer brighter (whiter?) lights in the kitchen/dining room areas. Sometimes in the living room. In the bedroom and upstairs hallway I want a more glowy, subdued lighting. Hospital-quality white ain't my thing.

There's probably a biological component as well, circadian rhythms and such which are more sensitive to blue light.

Another potential drawback with this new bulb - it looks like it radiates mostly sideways. That would be OK in some fixtures but it would suck if you wanted to light an area directly underneath a vertically-mounted bulb.
 
2013-03-07 12:37:52 PM  
Cool, Ill have to try one out. I've been slowly switching from incandescents to LED, skipping the CFL's.

The bulbs are getting better, both LED and CFL. We're getting smoking deals at Costco, too. I got a bunch of 60 watt equivalent LED bulbs for my living room lamp for $6 each. Previously, it was supposed to max out at 5 45 watt bulbs, but I went to 5 60 Watt(Equivalent) bulbs, got more light and less power usage.

Now that they arre rating color temp and lumens output on CFLs also, I am able to find some that aren't sickly, weak things, and I've started replacing them as I can. Once again, lower power usage, and I can put them side by side in a fixture now, and you can tell the difference(Outside of the whole 'squiggly tube' vs. 'egg on a base' thing...). Also on sale at Costco, $1.25 or something for a 4-pack. I'm just as picky as your wife when it comes to color temp and brightness, but I'm glad to say that these are finally being adressed to my satisfaction.

2013-03-07 12:44:19 PM  
I'm looking forward to LEDs that auto-adjust their color throughout the day, which can't be that far away. Like a lot of people I prefer a whiter, daylight balance during the day, but would prefer something that more closely mimics sunrise/sunset at each end of the day. I suspect our bodies are evolved to respond to the color changes.

Nope, they both have their uses. CFLs are cheaper, LEDs need heatsinks and voltage regulation circuitry. You can spend $15 on a single LED bulb, so you really need to decide WHERE is worth installing it.

Considering that the issue has been to have LEDs with omnidirectional light, I'd say that you're already covered. They've been making LED spots and floods for years now, and having trouble mimicking a "standard" light bulb.

Considering Energy Star 'certified' a gas powered alarm clock a few years ago, I'm not sure how much I care about the sticker.

2013-03-07 12:53:51 PM  
Why do I like yellow lights? Because I don't like farking up my circadian by getting lots of blue-light exposure at night. For that matter, I'd still like to have a bulb that more closely emulates an incandescent by shifting toward a warmer color temperature as it dims.

I'm happy as a clam about these bulbs, though, and not just because I've got a nice long position in Cree. :) They're cheap enough, and work with standard dimmers. Now let's have some that draw a full 60 watts, and crank out the lumens of a 300-watt bulb, only without the fires.

Yeah.  The other issue is that I switched the whole house to CFLs in 2007 or so, and I've maybe had to replace a couple in the six years since (*).  My first instinct would be to wait for the CFLs to burn out, but that might be 5 more years at this pace.  The minor efficiency upgrade over CFLs isn't a good trade with the cost of early upgrades.

LEDs are great for outdoor lighting (they deal better with temperature shifts, etc. unless you find cold-cathode CFLs, which tend to be pricy anyway), but I'm admittedly not looking forward to the day that random vagrants figure out that I have $20 bulbs ready to be unscrewed.  I mean, if people steal copper pipes from AC units, this is a much easier target.  Hopefully the price will hit $5 or so before that happens.

(*): For the inevitable "CFLs done lasted 15 minutes in my housetrailerdungeon" post, get your wiring checked and buy a reputable brand, not the cheapest thing on the shelf.  But it's probably your wiring.

Already been getting some...

Got a deal off eBay for 12 x 40w equivalent for 25 $... cool looking, very bright in the light it gives, but one reason I got them was that I believed that they'd have protective circuitry, and my lights in the bathroom keep burning out (regular and CFL).  Sadly, I've got one dead already and another that's appearing to be dying or is already.

But then again, these are probably fairly cheaply made.

Farty McPooPants: They are based in NC but where are the bulbs made?  If they're made in China, no thanks.


They've got a nice factory right here in Durham. They even do the semiconductor fabbing here. I see that they bought a manufacturing facility in China a few years ago, but that was their first expansion outside North America, and I don't know whether it's come online yet. They're definitely talking about adding more jobs here to ramp up production for these bulbs, though.

More efficient lighting also helps that 13 SEER air conditioner.  Most people don't appreciate that their old 60W incandescent bulbs are basically 9W of lighting attached to a 51W space heater with no ventilation.

Go hire an electrician to inspect your house top to bottom.  Incandescent bulbs aren't very sensitive to electrical problems, so if they're burning out there's something very wrong.  The electrician will probably charge a couple hundred bucks just for the inspection (before any repairs), but that's a lot cheaper than a fire.

I have to deal with Energy Star an awful lot and....those people did an awful lot of damage to a genuinely good program. Previously, a company used to be able to self identify their product category and other such data without filing a boatload of "under penalty of..." paperwork.

As there is no category for "gas powered alarm clock", these people fraudulently filed paperwork and likely faked test data. The program is a PAIN IN THE BUTT thanks to these people

I find they work fine with normal dimmers.  However, when you dim a LED, the colour temperature doesn't change.

And if you do use a dimmer meant for LED, you can dim the LED extremely low.  I have one in my daughter's room and when it's all the way down it functions as a night light.  It's great.

They have facilities in Hong Kong and Huizhou, China.  One is an LED manufacturing plant, the other a chip and component manufacturing plant.  However, they also purchased Ruud Lighting in Racine, WI back in 2011 and have added a significant workforce to their Durham, NC plant.  My guess would be manufactured in China and assembled in the U.S. so that they can get TAA compliance, but that is just a guess.

RexTalionis: We've been conditioned to expect warm lighting in the evenings for thousands of years. That kind of daylight-ish white light is just weird at night. My bedroom uses the daylight-style bulbs and my living room uses more yellowish bulbs and my bedroom is way less inviting a place than my living room, probably explaining my lack of success with the ladies.


Hundreds of thousands of years living next to campfires will do that to your genes.

...or lightning strikes. I lost a couple of CFLs when the power got zapped. Not common, but it does happen.

The CFL tubes themselves are pretty resistant, but the ballast circuits are easily fried.

How many light bulbs do you have in your house? How many do you purchase in a year?  Do you like being able to see at night?

While the minute details of how light bulbs work and why one is superior to another might not be important in your day-to-day life, they're hardly "inconsequential".

Wake me when the LED bulb market can match at least a 100 watt incandescent output. My house has many built in ceiling "can lights" and there are only so many of them. They currently have 100-120 watt bulbs. 60 watt equivalent ain't gonna cut it.

This.  Recently bought some 75-watt daylight CFL bulbs for my nightstand.  Best. Bulbs. Ever.


Until you break one on the carpet and you have to spend the next four hours on the floor with duct tape because the vacuum cleaner will cause any spilled mercury to go airborne.

Seriously, cleaning up a broken CFL is a colossal PITA.

60W-equivalent CFLs cost between $1 and $2 and only consume 12W or 13W.

However, I assume the LED is dimmable, it would be worth it for those types of lights.

FTFA "Buyers have been able to pick up a 40W-equivalent Ecosmart LEDs at Home Depot for $9.97 for some time now, but it's not a great bulb."

Did they describe what they didn't like about the Ecosmart bulbs in an earlier article? Granted, my apartment mostly has ceiling fixtures so these bulbs work perfectly well. I tested one in a desk lamp for a new pre-sleep reading light, but not surprisingly there wasn't enough ambient light to make it worth switching from the CFL I currently use. Maybe this new bulb will solve that problem.

2013-03-07 02:16:14 PM  

chimp_ninja: imfallen_angel: Got a deal off eBay for 12 x 40w equivalent for 25 $... cool looking, very bright in the light it gives, but one reason I got them was that I believed that they'd have protective circuitry, and my lights in the bathroom keep burning out (regular and CFL). Sadly, I've got one dead already and another that's appearing to be dying or is already.

Go hire an electrician to inspect your house top to bottom.  Incandescent bulbs aren't very sensitive to electrical problems, so if they're burning out there's something very wrong.  The electrician will probably charge a couple hundred bucks just for the inspection (before any repairs), but that's a lot cheaper than a fire.


Considered it and will do at some point, but I expect that it's not just a internal power thing as the city's power is always fluctuating here (even if in middle of city)... I get more power outage than country folks... even had to get a generator after two power outs that lasted a few days.

It's really weird... and very annoying... I now have an UPS with full display and I can see the brown outs and the spikes happening on a regular basis...

So if I bring an electrician in, I'll probably go with some sort of power filter... heck if I could afford it, a full backup system... even go solar.. but, not rich like some Farkers with their wicked setups I've read from some.

Home Depot already has LED lights for under $10 from EcoSmart, and they are the same price pojnts as Cree and have a 50k hour rating on them instead of 25k and they too are already energy star compliant.  Cree is offering nothing new, slightly worse product for the same cost and this is big exciting news why?

Yeah, CFL's are great, the only three real drawbacks in my mind are: Mercury cleanup (mentioned above), not dimmable, and the "warm-up" can be annoying, especially in colder areas (I have one in my garage).

LED's address all of these, and are even a little bit better on energy.  Really the ONLY drawback to LED lights that I can think of is the initial cost...and historically, the costs should start continue to drop as they become more ubiquitous.  Oh, the cost and some of them have problems with "flickering"...we have a small LED reading lamp that will flicker inexplicably (try saying that 3 times fast!).  My in-laws got some of the early LED bulbs (Phillips I think) to use on their ceiling fixture in the living room, because the ceiling it is 16' AFF and a paint to replace bulbs, so the long life was what sold them on the idea.  Then, my mother-in-law started getting migraines from the bulbs.  Well, she always got migraines, but this apparently got added to the list of triggers.

Perhaps reading the article might shed a little light on it:

The first point of attack is price. Breaking the $15 and $10 marks is big but, importantly, Cree is doing it with a quality lamp. Buyers have been able to pick up a 40W-equivalent Ecosmart LEDs at Home Depot for $9.97 for some time now, but it's not a great bulb.

I find the older Phillips ones can run quite hot.  If they're in a can they get really, really hot.  I had one in a can in the living room and it would start flickering on and off after a few hours.  I replaced it with a Luminus one from Costco which seems to work a lot better (it spreads the light out much better and runs much cooler).

Some of the older bulbs specify in their packaging that they're not intended for inverted installation-- they dissipate a good bit of heat from the base, and the design assumes some airflow around the bulb.  The newer bulbs seem to have this problem beaten.

These particular bulbs would be exactly the wrong thing to use, but I'll bet an LED bulb designed for a can would have even more of an efficiency advantage over incandescent -- you'd just point all the chips downward, and you wouldn't need a rear reflector and its attendant inefficiency. You'd need to make sure the heat can escape from the can, though.

I've been buying Inland 40W LED Bulbs at Microcenter for some time now.

None of them have burned out, and they provide pretty good lighting. $0.72/year cost of operation, 490 Lumens @ 3000K. $7.99, or $8,99 for the dimmable version.

They have a nice heavy heat sink on them.

I pick up a few every time I go in the store, but I've noticed others have discovered them now, and the store is now having trouble keeping them in stock.

Define "quickly."  They're what, three decades old now?  That's a decent run for a piece of technology these days, particularly any sort of technology that is in direct competition with the ultra-fast-moving semiconductor industry.  They're also still the cheap option.  CFLs are less than a buck at Costco, which means they'll probably hang on a bit longer.

Still, the Cree bulb is a welcome development, and it will most likely only get better from here.

czetie: I'm looking forward to LEDs that auto-adjust their color throughout the day, which can't be that far away. Like a lot of people I prefer a whiter, daylight balance during the day, but would prefer something that more closely mimics sunrise/sunset at each end of the day. I suspect our bodies are evolved to respond to the color changes.

Did you try a dimmable LED bulb? The problem might be the power line being inline between the controller and the light. Maybe the dimmable bulb will isolate the power line?

I have been looking into LED reverse lights for my truck and a VERY common problem is that when you put them in your stereo system starts getting a lot of static when you are in reverse, so it does sound like there is some form of interference or electrical noise caused by the electronics package in the LED. (Yes, most of the well regarded replacement bulbs I have seen are Cree and they still have this issue.) For most people, they just ignore the problem since how often do you really need to be in reverse? For other applications I would worry about it more.

Nah, I don't blame marketing. It was Philips' first stab at a BR30 (sorry, it wasn't a PAR30) LED.  The model itself was only on the shelves for a few months before it was replaced with an apparently much better model.

chimp_ninja: (*): For the inevitable "CFLs done lasted 15 minutes in my housetrailerdungeon" post, get your wiring checked and buy a reputable brand, not the cheapest thing on the shelf. But it's probably your wiring.


Actually, it might also be their fixtures.

I found that CFLs worked mostly great except in a couple of locations where they repeatedly burned out quickly. It turns out that if the metal tab thingy* inside the fixture that is supposed to make contact with the base of the bulb is too flattened, it won't make good contact, you'll get arcing, and your CFLs will have a very short life. Just bend the tab a little outwards so that it maintains pressure against the bulb when the bulb is screwed in, and those fixtures have the same bulb life as the rest of the house.

*I'm sure there's a technical name for the metal tab thingy, and hopefully somebody will be along to share it.

KarmicDisaster: Cyrorm: Home Depot already has LED lights for under $10 from EcoSmart, and they are the same price pojnts as Cree and have a 50k hour rating on them instead of 25k and they too are already energy star compliant.  Cree is offering nothing new, slightly worse product for the same cost and this is big exciting news why?

I don't like the ecosmart as much. The color for one thing.


What little I know about LEDs is a result of my weird fascination with LED flashlights.

A batch of LEDs made at the same time will exhibit some variability in brightness and color, due to random factors in the manufacturing process.  The LEDs are sorted into bins of varying luminous flux, chromaticity, and color.  So, for example, some nominally white LEDs from a given batch might be tinted somewhat yellow/green, or tinted blue, or appear perfectly white.  Some of these will be brighter or dimmer at a given  current.

Bins for Cree LEDs

Among flashaholics, this phenomenon used to be called the "Luxeon lottery" (dating from when the Luxeon high-flux LEDs were the only game in town).  One might have paid more to have a light made with an emitter rated highly for luminous flux, only to have a greenish tint that one might find displeasing.

In real world use, the difference is usually imperceptible, and for a white LED flashlight you'd probably only see it if you're shining the light on a white wall.

There can be a great difference in the cost of the various bins.  LED light bulbs may be using emitters from low-flux bins, as they are cheaper.  The more expensive LED light bulbs *might* be using better emitters.

But the German scientists claimed that several carcinogenic chemicals and toxins were released when the environmentally-friendly compact fluorescent lamps (CFLs) were switched on, including phenol, naphthalene and styrene.

i've got 1500lumen 5000k CFLs that only use like 23w so i'm set for a while.


Just had one of the four I have in the office die. Only about six months of use. Wiring is fine. I checked the whole house when we moved in and had to repair around 25% of the outlets and light-boxes.

I'll probably get some of Cree's outdoor spots for where I have motion detectors. CFLs and incandescents just don't last.

but.. but.. that's not warmer! that's a colder black body equivalent!!!

:P (yes i know "warm color palette" vs "actual black body temperature")

I also disagree, that piss yellow light is dim, makes everything look like crap and is just generally ugly.


Agreed. I loved GE's Reveal incandescents, which had all the power usage of the inc., plus the sterile lighting of the first gen CFLs.  Weird, but the best lit rooms I ever had.

Cree is an American company.

/I know, I know...

I can't find the location of manufacture on the bulbs from their website, I guess to find that out I'll have to go to Home Depot and look at the box

They have facilities in Hong Kong and Huizhou, China.  One is an LED manufacturing plant, the other a chip and component manufacturing plant.  However, they also purchased Ruud Lighting in Racine, WI back in 2011 and have added a significant workforce to their Durham, NC plant.  My guess would be manufactured in China and assembled in the U.S. so that they can get TAA compliance, but that is just a guess.


I think this is the case. I was disappointed they don't mention the manufacturing location on their site, esp since they are an American company.  I could see an American flag on the HD website, but the text was fuzzy.  Found a pic of the back of the package on The Verge, has a flag says "Assembled in America", so I guess you're right.

If so, it's probably coming from hot electronic components on the circuit board. I wouldn't expect much difference between CFLs and LEDs, and in either case I doubt it releases a significant quantity.

I haven't seen anyone in this thread mention halogen incandescents yet. They meet the new efficiency standards, look good, and are a nice middle ground for anyone who hates the crap CFL/LED bulbs but doesn't have time to scour the Internet to find a decent one.

2013-03-07 05:13:43 PM  

ChubbyTiger: Anyone want to weigh in on what should be considered a good CRI?


Usually CRI above 80 is considered good, but one must understand what effects CRI. CRI is a metric of color shift under a particular lamp with 100 being no noticeable shift in color. There are many things that effect color shift. Color temperature effects CRI but it is also dependent on light intensity. Color temperature is the temperature of an ideal black object that gives off that color of light. The higher the temperature the bluer and whiter the light, the lower the temperature the lower the more yellow the light.

The higher temperature the lamp, the more intense the light will need to be to offer good color rendering. At low intensity, high temperature lamps will give a noticeable blue hue color shift. At high insensity low color temperature lamps will give off a noticeable yellow color shift.

In spaces one wishes to have lower lighting levels, lower temperature lamps will offer the best rendering. Spaces in which one wants higher light levels, high temperature lamps should be used. Some places, you want both like a dinning room in your house. You want low intensity when eating but higher intensity when using your dining room table as a work table. Some commercial LED manufacturers make color temperature shift fixtures that shift the color color temperature as the intensity is adjusted with a dimmer.

Age also effects color temperature preference. As people get older they wish to have high light intensity so the preference high temperature lamps goes up.

Of course there is also personal preference. I'm still young and my eyes are still in good shape so I prefer lower intensity lighting with lower color temperature. I wouldn't put anything over a 60W equivalent in my house with my preference being 40W equivalents.

Depends on when it was manufactured.  A lot of older CRTs have cadmium or yttrium phosphors.  You wouldn't leave them lying around if a breakage happened.

It's certainly not "just glass", because that wouldn't make colors.  These issues are present in LEDs and other modern displays as well, which is part of why many communities have dedicated electronics recycling now in order to keep those metals out of groundwater/etc.
 
2013-03-07 05:27:08 PM  
Since we're sharing, I'll offer my favorites:
Sylvania micro-mini, soft white 2700K instant-on CFL bulbs, 100W-equivalent (23W actual). A good mimic to incandescent. I installed a 3-bulb floor lamp with these CFLs to replace a single-bulb torchiere-style that was using whopping 300W incandescent. The brightness/color change was slight and I'm happy with it.
For a whiter/daylight look, same brand but 6500K. I have these in the laundry room.
I wouldn't quite go with "instant" on, but they do warm up quickly enough.

jfarkinB: These particular bulbs would be exactly the wrong thing to use, but I'll bet an LED bulb designed for a can would have even more of an efficiency advantage over incandescent -- you'd just point all the chips downward, and you wouldn't need a rear reflector and its attendant inefficiency. You'd need to make sure the heat can escape from the can, though.


Tou WOULD think that. But I can't find any such thing.

I am an engineer so I know a little about specs (like looking at the lumens and not the marketing bs of "wattage equivalent") and I haven't found any reflector bulbs or replacement modules that approach a 100 watt R40. The brightest I found fall short of that and most of them are focused like a pin spotlight (probably to increase perceived brightness).   (they also need to be dimmable, or I end up spending even more to replace dimmers w/ switches)

Reflectors, or omnidirectional?


Reflectors (R-40s). And I need a wide flood light not a narrow spot (like many of the LEDs).

Right now I have some fairly bright CF R-40s with a good pattern and decent brightness. The problems with them are
A) Slow warm up time is annoying and rules them out for bathrooms or kitchens for us
B) They don;t really dim well. The go from 100% to 80% then out.

There is no reason to do this. Good LED bulb have decent heat sinks already, the LEDs themselves don't get hot, likewise, the diffuser doesn't get hot, either. I've got one right here at my computer desk (clip-on desk lamp), and it isn't hot at all - not even the metal hood around the heat sink is warm, and it's been on all day. As for the quality of the light, with LED bulbs it is all about diffusing the light... otherwise, you just end up with spotty, focused light.

I really don't understand why people have all these crazy ideas, and they've never even tried them out. Spend $8 and get one to try out.

I've been running the Inlands I mentioned above for over a year now and I've got no complaints about them, other than I have to gradually upgrade because they are still relatively expensive.

It's wide.  Just as good, if not better, than the CFLs they replaced in terms of dispersal.  Far better in terms of actual light output and of course basically perfect instant-on.

And 1350 lumens isn't good enough?  Are you wearing sunglasses in your house?

While there may be problems with modern sets, older color TV sets used red/green/blue phosphors to create the picture, an electron beam hit the phosphor and made it glow.

The biggest problem was actually X Radiation, the high voltage rectifier, which in my set, was tube  number 1B3, had to be shielded within a metal box along with the high voltage  or flyback transformer. The outside of the picture tube also had to be shielded.

The second biggest problem was the possibility of implosion. It was rare but it happened.

LesserEvil: I've been buying Inland 40W LED Bulbs at Microcenter for some time now.

None of them have burned out, and they provide pretty good lighting. $0.72/year cost of operation, 490 Lumens @ 3000K. $7.99, or $8,99 for the dimmable version.

They have a nice heavy heat sink on them.

I pick up a few every time I go in the store, but I've noticed others have discovered them now, and the store is now having trouble keeping them in stock.

[img2u.info image 200x200]


I got a bunch of the Inland 60's (and a couple 75's) to replace nearly all my bulbs (mostly because I'm SICK OF CHANGING STUPID LIGHT BULBS!)

I had a 180 watt bulb in a floor lamp -- I bought 2 light bulb socket doublers and screwed them together giving me a net 3 sockets in the lamp -- put 3 60's in there -- 180 watt light output that won't burn out and uses about 30 watts.

We will see how this works out. I have never been completely happy with the CFL's anyway. Some generate a lot is radio frequency interference. I hope these LED's are better.

... come to think of it, I can't remember the last time I changed a light bulb. And I have all CFLs.

I'm still using CFLs from the early-2000's ( GE 2-D dimmable CFL still running strong). I'm  enough of a dork to buy a LED bulb just out of curiosity, however.

germ78: Do you have to pay $30 extra for the extended warranty? Will you be hounded by some salesjerk to do so, or else he earns no commission on it?

/or is that experience a Best Buy exclusive?


Only the Home Depot people at the Contractor desk are on commission.

Is there such a thing as an affordable LED lamp bulb that has sunlight-spectrum quality? My peepers have become pretty adjusted to it and anything else either looks like old-timey orange or melt-your-corneas-out ultra-white.

Kazan: the_sidewinder: Kazan: 2700K? Aka "Incandescent Piss-tinge"? fark that shiat.

If you really hate that, the article points out that the 60w equivalent will also be available in a Daylight variety

i've got 1500lumen 5000k CFLs that only use like 23w so i'm set for a while.


Myself I have 5000k 1200 lumens that use 20w but they only cost £0.10 each so I got 30 of them. I`m set for bulbs for a while and it only cost me £3...

max_pooper: SpectroBoy: jfarkinB: These particular bulbs would be exactly the wrong thing to use, but I'll bet an LED bulb designed for a can would have even more of an efficiency advantage over incandescent -- you'd just point all the chips downward, and you wouldn't need a rear reflector and its attendant inefficiency. You'd need to make sure the heat can escape from the can, though.

Tou WOULD think that. But I can't find any such thing.

I am an engineer so I know a little about specs (like looking at the lumens and not the marketing bs of "wattage equivalent") and I haven't found any reflector bulbs or replacement modules that approach a 100 watt R40. The brightest I found fall short of that and most of them are focused like a pin spotlight (probably to increase perceived brightness).   (they also need to be dimmable, or I end up spending even more to replace dimmers w/ switches)

If you know of such a device I would consider it a kindness for you to post it here.

Those max out at 1K lumens and a CRI of 67. I guess I will need to wait another year or two.

Shazam999: t's wide.  Just as good, if not better, than the CFLs they replaced in terms of dispersal.  Far better in terms of actual light output and of course basically perfect instant-on.

And 1350 lumens isn't good enough?  Are you wearing sunglasses in your house?


Thanks for the info.

Our house is on the large size and the cans are spaced for 120-150 watt R40 bulbs. The architect like the look of fewer cans (and it's cheaper to build), but now those bulbs are hard to get. (I never thought I would be buying "black market" light bulbs)  Also, in the foyer the floor is brown so a lot of the light is wasted. (and I need wide floods, not spots)

1350 Lumens is good enough, but a hair low.

RexTalionis: Kazan: vpb: I suspect they just don't like change.

yes.

RexTalionis: Because people like warmer colors and that warmer lighting is easier on the eyes.

but.. but.. that's not warmer! that's a colder black body equivalent!!!

:P (yes i know "warm color palette" vs "actual black body temperature")

I also disagree, that piss yellow light is dim, makes everything look like crap and is just generally ugly.

We've been conditioned to expect warm lighting in the evenings for thousands of years. That kind of daylight-ish white light is just weird at night. My bedroom uses the daylight-style bulbs and my living room uses more yellowish bulbs and my bedroom is way less inviting a place than my living room, probably explaining my lack of success with the ladies.


Yeah, it's the lighting that makes you look like a man-child who still collects comic books and takes pride in unlocking the next level in the latest game. Why does l

chimp_ninja: 4) Why can't I find this study?


Because it's bullshiat

Why are no details provided?

Because it's bullshiat

Why is it that when I search for the "Federation of German Engineers" it only returns this "study"?

Because it's bullshiat

I saw a reference to this article on some other web forum a few months ago, and 30 minutes or so  with The Google led to the inescapable conclusion that  1)) the only websites that reference this "study" are ALt Med sites, and people with an axe to grind or a vested interest in these bulbs not becoming popular, and 2)  not a single one of them provides a primary source for this "study" - they invariable all link to one another

Ah, R40.  You don't want the R30 then, they'll look tiny in the cans.  There are R40 LEDs, look around.

I did pretty much the same thing.  I replaced the CFL in my headboard lamp with an LED bulb, and I have absolutely no complaints.  More recently, I swapped out the CFL's that came with a pair of Ikea lamps since the CFL's it came with are very slow to warm up and have just enough flicker to be annoying (the LED bulbs don't flicker at all as far as I can tell).

I plan to eventually replace all of my CFL's with LED bulbs, but only as they burn out (the energy savings isn't enough to make it worthwhile to replace a working CFL).  And since I still have about half of a Costco box of unused CFL's, that could take ten years or so.

t3knomanser: Samwise Gamgee: Fireside, candlelight, etc. Warm, relaxing, comforting.

Firelight and candlelight are not exactly good lights to  see by. They're delightfully decorative, but hardly practical. If I want to actually do things, I much prefer a crisp, white light. I've got this LED lamp that's absolutely brutal- you have to light the room with it indirectly. Bounce it off a wall, and fill the room with light. Love it.


That's great during the day, but I'm at work all day where I work under horrid bluish fluorescent lights. When I get home in the evening I want a warm glow.

It's funny - I put black electrical tape over all the annoying blue LED's on all my electronics because it impeded sleep, yet I typically have no problem falling asleep with my bug-light lamp on...

Pelvic Splanchnic Ganglion: Rwa2play: Kazan: 2700K? Aka "Incandescent Piss-tinge"? fark that shiat.

This.  Recently bought some 75-watt daylight CFL bulbs for my nightstand.  Best. Bulbs. Ever.

Until you break one on the carpet and you have to spend the next four hours on the floor with duct tape because the vacuum cleaner will cause any spilled mercury to go airborne.

Seriously, cleaning up a broken CFL is a colossal PITA.


Is this the new RW talking point when it comes to lighting technology? I wonder how our species has survived two generations of contact with fluorescent lighting if you're getting your knickers in a twist about one lousy CFL...
