What to do if your CFL bulbs burn out too quickly

I’ve been hearing a lot of complaints about CFL bulbs lately. I’ve written about how to address premature CFL burnout before, but I guess it bears repeating. It’s a five-minute fix, usually, to get the bulbs to last a while, so I guess the question is whether you want something that works well, or something […]

Why you can’t use LED bulbs in a garage door opener

I spent Independence Day patriotically replacing my garage door opener. OK, you got me. I have no idea how you patriotically install an opener. But that’s less important than a curious statement I found in the manual: Don’t use LED bulbs.

Another month, another go-to LED bulb

LED lighting seems to change constantly. I read about Cree’s LED bulbs a good 12-18 months ago and they sounded too good to be true. In a way, they were, because you couldn’t buy them anywhere. The wait is finally over–they’re finally available, though only at Home Depot. I tried out their 800-lumen (60W equivalent), […]

The new Philips 420240 10.5-watt 800-lumen LED bulb

I picked up a couple of the new Philips 10.5-watt 800-lumen LED bulbs this weekend. All around, they’re the best sub-$20 LED bulb I’ve seen yet.

LED bulbs and breakability

A longtime friend posted something on Facebook about CFL bulbs–namely, that in addition to containing mercury, that they also emit ultraviolet light. I thought everyone knew that fluorescent lights emit more UV than other types of lights and that wasn’t news, but maybe not. I pointed out that LED bulbs don’t emit any UV light […]

The lightbulb reinvented

Timothy Hunt asked me (via Twitter) if I’ve seen the lightbulb reinvented, an LED bulb that screws into a standard socket but has wi-fi capability so you can tune its light temperature and otherwise control it with a smartphone. I hadn’t. But I found it interesting, and appreciate the mention.

A preliminary review of the Inland warm white A19 LED bulb

Micro Center had the Inland warm white A19 LED bulbs on sale this week and had a hard time keeping them in stock. I snagged an 800 lumen (60W equivalent), non-dimmable bulb, which uses 10 watts, for $13. It’s not the state of the art in 10W LED bulbs, but the price is right and […]

When to upgrade to new LED bulbs

PC Magazine asks when it’s worth upgrading to the new Philips L Prize-winning LED bulb, lamenting its high price and long payback time. I can only say what I plan to do, based on my experience with high-efficiency bulbs. I was one of those guys paying $9 for CFL bulbs nearly a decade ago.

LED lighting gets cheaper

I saw this week on Cnet that Pharox is selling basic, bare-bones LEDs direct from its web site, hoping to get consumers to try out LED bulbs. The Pharox 300 is a 6 watt, 360 lumen bulb priced at $6.95. The Pharox 200 is a 5 watt, 240 lumen bulb priced at $4.95.

Review: The Utilitech Pro 430 lumen 7.5 watt LED bulb from Lowe’s

LED lighting is slowly getting cheaper. Home Depot has its 40W equivalent bulbs under $10 now, and Lowe’s countered with a $13 40W equivalent. The Lowe’s bulb uses less wattage, so I think that’s the better value. I bought some.
