The All-Powerful Atheismo: Wook: Rapmaster2000: The libs want us to put all of these LED bulbs in our houses, but did you know that there's more Gallium Arsenide in a single LED than there was on the entire Hindenburg!?

It's true. Look it up.

[o.onionstatic.com image 630x441]

Speaking of which, I worked for a German MOCVD company which designed tooling for GaAs deposition for use in LED manufacturing. The customers (producers of LEDs) were in China. Meanwhile, here in the US Obama's pitching Solar (which we all (in the industry) knew 4 years ago it was total bullshiat). Now we will be giving US dollars to China, which also made Germany rich. Bush's fault? I think not.

Wharrgarbl

China is investing more heavily and successfully in solar than we are, and succeeding quite well. They've managed to make single junction panels quite cheap.

I know. I was there.




Funny, I was a semiconductor process engineer for 10 years. Our company folded about 2 years ago. I went into Defense. Approximately 7 of my research colleagues took jobs in Solar. Only one of them is currently working. All of the other Solar companies have folded. Solar is good assuming you have cheap labor. Manufacturing in the US is expensive. Excessive regulations and Unions don't help either.

Keep your Wharrgarbl to yourself Sonny, the world ain't unicorns and rainbows!

Atomic Spunk: Why is it that LED flashlights and car headlights are very bright, but it's damn near impossible to find an LED lightbulb that is brighter than a 75 watt incandescent?


It's not impossible! They just cost around $30-$50 and use around 15W of electricity.

For home applications, get the ECS 8.6W series available at Home Depot for $10 a pop. It's the only LED A19 bulb that will work perfectly with X-10 automation and the socket rocket, unless they've changed the design already. For outdoor floodlights, check these out. Very tight and clean beam.

jshine: IrateShadow: Ivo Shandor: They'll go away eventually, once the novelty wears off. Blue LEDs used to be one of those mythical* items that you would tell the new kid to find, like a left-handed screwdriver or a 1-farad capacitor. Engineers are still getting over the fact that they actually exist now.

That was like 10 years ago. Tech moves fast enough that they should be old hat by now. What bothers me is that everything these days is ultrabright and packaged in clear resin. I miss the old low-medium intensity packaged in colored & frosted resin. They were much more useful as indicators.

Hah -- you'll know your equipment is powered on when your retina has a hole burned into it from the indicator lamp.

A combination of price and directionality. LEDs emit narrow beams that makes engineering a bulb that can light up a room kind of a pain in the ass. Plus people aren't willing to pay $250+ for a lightbulb the way that they are for a specialty headlight or flashlight.

There are several successful solar companies right in my area. Are the panels cost effective? They have a ROI of something like 10 years right now, so it's debatable. Research is also constantly continuing.

your statement that solar is "total bullshiat" is still retarded no matter what your experiences are in the solar industry.

This. Great bang for the buck and they offer excellent light. The sell out consistently, so be persistent checking the store or just order them online.

theMagni: I brought several of my flashlights last time I went on vacation. (I was diving) They were the brightest flashlights in the country, even the police didn't have anything close.


Just got back from a week at the beach. Late at night, I'd watch the beachcombers walking up and down with their flashlights.

Ten years ago, they were all dim yellow glows, with the occasional brighter yellowish-white.

Two or three years ago, you started to see the occasional dim bluish spot among all the yellow ones.

This year, I barely saw a single incandescent glow. They were nearly ALL high-color-temp LEDs -- from the cheapest keychain light to the 600-lumen bike light I sometimes carry.

Somewhere in the last couple of years, white LEDs, once science-fiction, became not only better but cheaper than incandescent flashlight bulbs. Soon enough, the same thing will happen for general-purpose indoor lighting. I'll be happy to see it.

I held a 1-farad capacitor. One of my friends was using it as a toy.

Charge it up, then touch the contacts to a sheet of aluminum foil. Large sections of the foil would just be.... gone.

No, that wasn't LED. I forget exactly what they're called, but said friend with the 1 farad cap also had a frequency counter that used a similar display. It had all ten numbers in a stack and illuminated one at a time. For the life of me, I can't remember what it was called..

No, those looked like Nixie tubes -- basically a neon bulb with ten electrodes, one for each digit. But looking more closely now at a movie still, it almost looks like a fiber-optic arrangement with incandescent light:

I think the individual dots are too small to be individual "grain-of-wheat" incandescent bulbs. I'll have to look into this a little more.

I stand by my claim that 4 years ago, those in the industry did know it was bullshiat, my colleagues that went into it beforehand knew it. The executives at AMAT pulled out and lost 100s of millions in the process, that was a wake up call to the industry.

When do light bulbs simply go away? Even if LEDs don't live up to their fifty year lifespan, something that lasts twenty five years doesn't really need to be removable. In our age of constant decor remodels, it's likely that a light fixture will be taken out of service before the LEDs give out. No doubt light bulbs will continue to exist but over time they should become a specialty item rather than something you can buy at the corner gas station.

It'll be interesting to see how lighting design changes. Will we have lamps in which there is no bulb at the top but instead hundreds (thousands?) of tiny LEDs embedded into the lamp shade? Will that form simply go away with LEDs becoming parts of the wall or ceiling or even the flooring? If the price per lumen continues to drop like it has been, things are going to get very interesting.
