U.S. bulb factories will stop producing best-selling 40-watt and 60-watt incandescent bulbs from 2014. According to this prohibition adopted in 2007, US eliminated incandescent bulbs more than 100 watt since 2012, and discontinued 75 watts and 100 watts incandescent lamps since 2013. This controversial law designed to promote energy-saving compact fluorescent lamps, LED light bulbs and other energy efficiency lighting.
People can replace fluorescent lamp to halogen, compact fluorescent light bulb, LED lights and energy efficient incandescent, experts pointed out that efficient incandescent approximately cost $ 1.5 each, although far more than the traditional incandescent $ 0.5, but it with doubled life, the energy consumption is also reduced by 28%.
This legislation is signed by former President George W. Bush in 2007, this provision is intended to solve the issue of old-fashioned incandescent with low energy efficiency; according to the EPA’s data, only one-tenth of the power consumed is converted into light by this bulb, the rest of the energy is wasted as heat.
