Pixi LED lights are environmentally friendly. They switch on instantly, generate very little heat and use less energy than current troffer, incandescent, fluorescent and luminaire lighting fixtures. A traditional incandescent light bulb dissipates about 92% of its energy as heat; an LED bulb, about 10%. Pixi LED bulbs are rated to last up to 50,000 hours or more. That's about 17 years when used for an average of eight hours a day. So you change them less frequently — saving energy, time and labor. And Pixi LEDs contain no mercury or other toxic substances, so when it's finally time to dispose of them, they won't harm the environment.
