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.

LED is the future, but I don’t think it’s here yet
San Jose Mercury News columnist (and fellow Mizzou alumnus) Troy Wolverton has been testing LED bulbs. His conclusion: The quality of light is good, prices will continue to fall and efficiency will continue to improve, so they’re the future, but the future isn’t here yet. I’m always trying to wring the last bit of value [...]

So maybe CFLs burning out a little early isn’t entirely bad?
I was out buying toilet parts today (more on that in a minute–I’m sure you’re thrilled), and while I was there, I looked at light bulbs. I needed a few. And I noticed something. The 40W equivalent CFLs use 9 watts today. The same as LEDs. So I bought a package of (4) CFLs for [...]
