New Material May Make LEDs Less Creepy

Posted January 19, 2013 12:13 PM

From Science 2.0:

In America, the government banned incandescent light bulbs, convinced that if they banned them, the free market would replace it with something affordable, effective and efficient. In reality, since there was no good alternative, people just horded light bulbs. The automobile did not supplant the horse and buggy because horses were banned and banning regular light bulbs was not going to make compact fluorescent bulbs or light emitting diodes popular.

No charts, no graphs, no spectrum, no substance. Marketing only.

What's the big deal about using a "warmer" phosphor (which, ironically, is a cooler color temperature)?

I noticed LED 40W equivalent bulbs at the hardware store the other day at about $10 each. I still have incandescents, and I think I probably replace a bulb in my house maybe once or twice a year, so I don't get too excited about a bulb that lasts 25X as long. I expect that it would take a long time to pay for itself in saved electricity. And 40W is too dim for me to see to read! I'll wait for them to be cheaper and brighter.
