Frequently Asked Questions
Why does the light source type matter?
Different light source technologies convert electricity into visible light at very different efficiencies (luminous efficacy, measured in lumens per watt) -- LEDs typically produce 5 to 7 times more light per watt than an old incandescent bulb.
