New Reasons to Change Light Bulbs
For use in the lamps and light sockets of your home, LED bulbs have been slow to arrive, mainly because of their high price.
That’s a pity, because LED bulbs last longer and use less power than older ones, and with prices falling, a change makes even more sense, David Pogue writes in The New York Times.
LED bulbs are a gigantic improvement over incandescent bulbs and even the compact fluorescents, or CFLs, that the world spent several years telling us to buy. LEDs last about 25 times as long as incandescents and three times as long as CFLs; we’re talking maybe 25,000 hours of light. Install one today, and you may not own your house, or even live, long enough to see it burn out. (Actually, LED bulbs generally don’t burn out at all; they just get dimmer.)
You know how hot incandescent bulbs become. That’s because they convert only 5 to 10 percent of your electricity into light; they waste the rest as heat. LED bulbs are far more efficient. They convert 60 percent of their electricity into light, so they consume far less electricity. You pay less, you pollute less.
But wait, there’s more: LED bulbs also turn on to full brightness instantly. They’re dimmable. The light color is wonderful; you can choose whiter or warmer bulbs. They’re rugged, too. It’s hard to break an LED bulb, but if the worst should come to pass, a special coating prevents flying shards.
Yet despite all of these advantages, few people install LED lights. They never get farther than: “$30 for a light bulb? That’s nuts!” Never mind that they will save about $200 in replacement bulbs and electricity over 25 years. (More, if your electric company offers LED-lighting rebates.)
Surely there’s some price, though, where that math isn’t so off-putting. What if each bulb were only $15? Or $10? Well, guess what? We’re there. LED bulbs now cost less than $10.
