Cree bulb

The performance of LED bulbs continues to improve in terms of light output (lumens) and quality (color rendering index). Cree manufactures the LED light source that's put into light fixtures, but earlier this year it released a demonstration bulb it expects will come to market later this year. It will give off more than 800 lumens, making it a replacement for 60-watt incandescent bulbs, and consume less than 10 watts. It's designed for even light and suitable for many uses, not just spotlights.
