You are right, i didn't consider the LED usage in a more industrial environment. The robustness of a LED is also worth to mention. But i also believe that LEDs will replace the lights in our homes within the next few years. Here in the EU, normal filament bulbs are not allowed anymore and that will also increase the sale of LEDs. Energy saving light tubes are not very popular because of their mercury, so i think most people will go for LEDs, also for residential use. Do you have any LEDs at home?
