It's no problem to get 50,000 hour LED bulb but you going to pay $10+ for each one. Mainly due to the metal heat sink. American companies are still machining blocks of metal. The Chinese adapted other heat sink technologies to make thinner heat sink fins, when combined do the same with less materials. I'm pretty sure the next leap will come from LCD scale LEDs combined into bigger arrays which require even less for cooling since they can be printed onto various materials. |
