What if you could buy a lightbulb that would last for 20 years, so you would rarely ever have to replace bulbs in lamps and light fixtures?
As it happens, such a lightbulb has just come on the market. It’s the new 20-year LED lightbulb developed by Philips and the winner of the U.S. Department of Energy’s L Prize, which is an initiative to develop alternative sources of lighting.
According to Philips, the bulb will use only 10 watts of power and will save $8 per year if it’s used four hours a day. It’s expected to last 30,000 hours, which is 30x longer than incandescent bulbs. (Not that it matters, since those are being phased out anyway.)
Compared to compact fluorescent bulbs, the energy savings are similar, but the Philips bulb will last three times longer than a CFL and gives off a more natural-looking light. It doesn’t contain the mercury vapor that’s inside CFL’s and which creates a toxic hazard when they break.
One thing that is problematic is that this new bulb will cost significantly more than CFL’s, which average around $5. The new bulb costs $60 but Philips is discounting it to $50 and looking for other ways to bring the price down, including making deals with electric companies. The eventual goal is to price the bulbs in the $20-30 range.
What do you think fellow Eco Warriors? Would you spend that much money on a lightbulb if it meant that it would last far longer?
