L ight-emitting diode (LED) bulbs, center, are the way to go, says a UC Berkeley energy economist. Now is the time to r eplace all your incandescent bulbs , left. And replace your compact fluorescent light (CFL) bulbs, right, when they burn out. com *Over 5 million engaged readers weekly* When it comes to lighting, I’m no early adopter. I was never a fan of those curlicue compact fluorescent lights (CFLs): the light quality is bad. The low quality and hassle outweighs the savings. So I hope I have the cred to convince you that now is the time to swap out (almost) all of the incandescent bulbs in your house and replace them with light-emitting diode (LED) bulbs. A standard LED bulb now costs only $3-$4, less if your local utility subsidizes them. That LED uses 8. 5 watts to produce the same amount of light as a 60-watt incandescent. The Department of Energy generally calculates costs assuming a lightbulb is used three hours per day, but let’s be super conservative and assume it’s on only one hour a day. If you pay the average residential retail rate for electricity in the U. S. (12. 73 cents per kilowatt-hour), you would save $2. 39 in the first year, 60 percent to 80 percent of the purchase cost. If you’re in a higher cost area (nearly all of California), the payback is even faster. LED bulbs are touted to last for more than 20 years (at which point it is fine to toss them in the regular trash). The spreadsheet I keep of every lightbulb in my house (yes, I really do, which is how I know that my CFLs have lasted only one to two years) shows that none of the LED bulbs I’ve installed, going back to 2009, has yet failed. If that new LED lasts even a bit over a year, replacing the working incandescent today will still save you money. If you hardly ever use it — that bulb in the cellar that’s on for only a few minutes every week or two — skip that one. In fact, you could use all the incandescents that you remove from other fixtures to replace the one in the cellar every few years for the next century. But you aren’t just saving money with LEDs. You’re also saving energy and the planet. The energy that goes into making an LED is a small fraction of the $3-$4 cost. Compare that to the $2. 39 (or more) savings each year, which is all energy. The math for saving energy is even more compelling than it is for saving money. So if this is such a no-brainer, why are you still reading this article instead of replacing your incandescent bulbs. “LED bulbs prices are still falling, so by delaying I will save even more money. ” LEDs are indeed going to get cheaper, but not fast enough to justify waiting. You will save so much in the first year after replacement that unless LEDs are going to be nearly free a year from now (they aren’t), you’d still be better off doing it today rather than waiting. “I prefer the light quality from the traditional incandescent bulbs. ” With the old CFLs, the difference was so obvious that even your hipster nephew who always wears sunglasses could tell the difference. Switching from incandescents to warm-light LEDs (labeled 2700K-3000K) is much less likely to bother you. Still, if you are a lighting aficionado, scoop up all the incandescent bulbs the rest of us will be throwing away. “Throwing away a working lightbulb is wasteful. ” You’re missing the point: By not wasting the tangible incandescent bulb, you are instead wasting electricity, which may be invisible but still uses more of the world’s scarce resources than the bulb. Not unless the light really bugs you. They save almost as much money as an LED until they burn and you have to deal with throwing them away. Actually, that’s not really a concern: LEDs have taken over the market so completely that many stores no longer sell CFLs. So, buy your LEDs in 2017 and save money ever after.
