A thought on LED lighting

Recently I've been designing a new light for my kitchen, my current one is old and I want to make something unique. However I've wanted to use wine bottles in it's construction and while they are strong as hell I don't know they would handle the heat from even fluorescent bulbs over the course of time. Then I remembered that LED lights last for nearly ever and generate almost no heat. This no heat issue is at the core of why LEDs are so efficient at generating light. Incandescent and Fluorescent light waste a lot of energy in heat, this is why they use so much power to produce the same amount of light. Now I know this isn't a new concept, but really even though I do know the science behind it I don't think about it very much. I think it's interesting when you remember something you should be thinking about.
