This is a green light bulb, but not in the sense that it shines green light. No, this is the first bulb to hit the mass market with an eco-friendly LED light source. It consumes just 7W, yet produces the equivalent light output as a 40W incandescent bulbs. It also has a lamp life of up to 45,000 hours – some 45 times longer than its its older brother bulb and 25 times longer than traditional halogen filled lights. Go environment!
