Energy Efficiency Part 4 Lighting

There has been a lot of talk in the lighting industry about LED lighting. LED, or light emitting diodes, is an exciting technology, and the specs are incredible. They last 400,000 hours and a 2-3 watt bulb is roughly equivalent to a 40 watt incandescent. Also, it emits virtually no heat, whereas an incandescent emits 90% heat and 10% light. Also, it is brilliant light used in many commercial applications like stop lights...(When was the last time anyone has seen a bulb being changed on a stop light)

There is one small issue: LED is great for everything, but white light. Even the bulbs with good CRI(color rendering) offer a slightly bluish hue. LED sales will probably accelerate when GE, Phillips or Sylvania invest as they have in fluorescent.

Speaking of fluorescent, look at the environmental impact of changing just 7 bulbs in your home assuming 4 hours use. This is just New England.
