Resurrecting an old thread to ask a couple of questions about LEDs:
LEDs consume less power and create less heat. So, does anyone know why:
1- LED bulbs are built like they have huge heat sinks?
2- I can never seem to find 100W replacement bulbs? They always seem to be 40~60 watt replacements...with the occasional 75 watt replacement. I have many locations where I'd like to have 100 watt-equivalent bulbs on a dimmer, to allow brightness for tasks and dimming for normal or mood lighting.
Mark, its the way that an LED functions on the atomic level. A traditional light, generates light from heating the tungston to a ridiculous temperature, hence the reason they use tungston... LED's are a much more eloquent (scientific) way of generating light.....
When i was in school for electrical stuff, we spent a large amount of time on Diodes, which included LED's.. However, i do not remember the best way to explain it to you, so you will have to do some reading.. I found these two articles. They are pretty good, the second one seemed to go a bit more in-depth (i did not "read" the entire articles, i skimmed them for content)
