The Future is Brighter with LED Light Bulbs

We’ve been gradually, as the prices dropped, been converting our home to LED lightbulbs.

A few years ago, we jumped on the CFL bandwagon. It was one of our earliest stories on this blog, back in 2006. And we went hunting for dimmable CFLS.

We were convinced at the time, that CFLs would continue to improve, as would the dimmable type. However, dimmable CFLs burn out, and don’t quite have the dimming we’d like.

The common complaint about many CFLs is that they do not come up at full brightness, and the color output doesn’t quite match incandescents.

LEDs, however, have none of these shortcomings, although they can be highly directional light. They use less energy, they are typical dimmable, their color performance is more like an incandescent bulb and they last longer. The last longer part is relative, however.

Early models haven’t lived up to their longevity, by most reports. We haven’t had the decade to test them out, but Gadget Wisdom Headquarters is now 90% LED powered. The holdouts had been PAR20 and PAR30 bulbs, which were still $30 a piece. But the local Costco is selling 75 watt equivalent PAR30s for only $15. We got two to test, and will be expanding.

We also have a fixture that uses bulbs with a E12/candelabra base, and it is harder to find 40-60 watt equivalents with this base. They will come, we’re certain. They are hard to find in CFLs as well.

In several rooms, we’ve installed LED strip lighting from Ikea. They offer two models, the more economical Ledberg, and the more flexible Dioder. The Ledberg is one long strip, the Dioder can be installed as four separate strips, and other configurations. It is perfect for display areas, bias lighting, and undercabinet needs.

One of the biggest problems we’ve had was solved recently, trying to understand lumens to traditional watt ratings. The above diagram was shown to us, which has been very useful.

If you are reluctant to spend a lot, you may be able to justified a few strategically placed $10 LED bulbs in certain fixtures, which is the way we started. Either way, it is where we are all going eventually

LED Lightbulbs That Don’t Stink Coming Soon

We love the idea of LED lightbulbs. Like so many technologies, CFLs just started to get good, and adopted by the mainstream when the latest thing comes. LED lightbulbs last over ten times longer, use less electricity, and…are dim. Very very dim.

We can’t even find equivalency on most LED bulb packages we’ve seen. We’re used to CFLs being categorized as the equivalent of a specific watt incandescent. Those stats are suspiciously missing from LED packaging. They use the more accurate lumens…but how many people have a sense of what a lumen is?

We checked the lumens on a  CFL and compared them to the LED and found it…again. DIM.

The New York Times reports that Osram Sylvania’s  Ultra bulb, available in August, and Philips’s EnduraLED, which will be in stores in the fourth quarter, will use just 12 watts of power to equal the light output of a 60-watt bulb. The 60-watt bulb is the standard of light bulbs.

The prices for these bulbs will be $30-$60…and hopefully in 2 or 3 years, down to $20, which is more expensive than a CFL bulb…but it does last ten times longer, uses less electricity, and doesn’t have some of the CFL issues, such as mercury usage.

Perhaps we’re skeptical, but we’ll believe it when we see it. We’ll gladly be early adopters, and hope LED bulbs get to where we’d invest.
