I got an LED bulb, and it is fabulous.

I half-heartedly checked Home Depot’s web site today, and saw they had 429-lumen, 8.6-watt (40W equivalent) LED bulbs at my local store. Finally!

So when I had a chance, I drove over, plunked down my 19 bucks, and brought one home.

It’s not perfect. But I like it an awful lot.I tried the bulb out in a lamp first, to test the light quality. It’s very similar to the last batch of CFLs I bought. Not quite as yellow as my remaining incandescent bulbs, but nice.

It’s not quite bright enough to use in a lamp, and it’s fairly directional. You’ll want at least a 60W equivalent for that, and probably more. Give it time.

In my son’s bedroom, the light worked great. It works nicely in overhead lights, and it’s dimmable. Dimmable CFLs are expensive and hard to find, so I might as well buy LED bulbs instead since they use less power and last 2-3 times as long.

In operation, I found the LED bulb never got uncomfortably hot to the touch.

LED bulbs produce no UV light, so they won’t attract bugs and they won’t cause the pictures on your walls to fade. That sounds like a plus to me.

And, believe it or not, they’re assembled in the USA. Presumably most of the components, if not all of them, are made in China, but LED bulbs are one of the few things you can buy that support manufacturing jobs here in the States.

The bulbs have a five-year warranty. I suggest saving the receipt and perhaps the packaging, and writing the date of purchase on the base of the bulb in pencil. That way if the bulb fails prematurely, you can do something about it.

The 46-year life expectancy claim sounds overly optimistic, but 15-20 years wouldn’t surprise me.

I suggest you “burn in” the bulb by leaving it on for 24 hours straight. Like any other electronic device, if it survives that first 24 hours of running continuously, it’s likely to last years.

If the bulb is going in a bedroom or someplace else where leaving it on for 24 hours is impractical, put it in a lamp and leave the lamp on for 24 hours, then install the bulb where you intend to use it.

At $19 a pop, I’m not going to run out to convert the whole house. But as old bulbs burn out, I’ll buy LEDs to replace them. As time goes on, they’ll only improve, and prices will come down. But these bulbs are good enough to be useful today.

The energy savings isn’t chump change–LED bulbs pay for themselves in a couple of years if they replace old-fashioned incandescent bulbs. Not only do you get more lumens per watt, but the less wattage you consume, the lower your cooling bills will be. I was an early adopter of CFLs–I have them everywhere but my kids’ rooms, and a seldom-used light in the shower of one bathroom. Between that, my thermal curtains, and a programmable thermostat, I haven’t had a $200 electric bill in years.

Energy isn’t going to get any cheaper, and we consume more of it per person than the rest of the world. We can voluntarily cut our energy usage, or we can wait for China and India to show up with guns and force the issue. I’d rather cut it voluntarily.
