Re: Becnhmarks of Innovation
Even incandescent lamps do not produce white light. They produce mostly red light.
Early LEDs used power to obtain bright light. Those 24 VAC LEDs installed in 1985 and running 24/7 since then are still working today. Compare that to the incandescent bulbs they replaced - that were replaced every 3 to 4 months. |
