LEDs: Where are they now?

If you've been hoping that LED (light-emitting diode) bulbs will soon replace your compact fluorescent and incandescent bulbs, brace yourself for more of a wait. LED technology holds enormous promise, but it probably will not be a widespread viable option for most consumers for at least a couple of years.    

The list of benefits is long. LEDs are mercury-free, long lasting, durable, and they have the potential to be more energy efficient than CFLs. At the moment, though, the quality of the products on the market varies widely so you have to shop wisely. "I'm very excited about the potential LEDs offer," says Alex Wilson, president of BuildingGreen. "For the time being, consumers need to be very careful about products making claims that seem too good to be true about the energy performance of LED lighting products."

There are some quality products on the market today, but price is often a barrier. "It remains the Achilles heel of LED lighting," says Wilson. "It's going to be some time before the price comes down to be competitive with incandescent or compact fluorescent light bulbs."

For now, holiday lights are one of the most practical and affordable applications for consumers. "There is no more efficient way to produce colored light than with LEDs," says Alex Baker, lighting program manager for Energy Star. As prices continue to come down, he says, LED decorative string lights will be a no-brainer for consumers because the conventional versions burn out more quickly and use more energy.  

LED technology also suits flashlights well. "Flashlights don't use a lot of energy," says James Brodrick, solid lighting program manager for the Department of Energy. The big reason to buy an LED version, he says, is that it won't break if you drop it and the batteries last for a long time.    

Desk lamps, under-cabinet lights, and recessed downlights can all make good use of LEDs at this point in time.

Buying Tips

  • Look for the Energy Star label. You'll find it on holiday lights. The program just started certifying other products in September so other LED lighting featuring the seal should appear on store shelves soon.
  • Compare prices. In this case, you aren't looking for a bargain. "You get what you pay for," says Baker. "If you're getting an LED-based product and it's about the same price as an incandescent or fluorescent, chances are the quality is not there."
  • Do your homework. The Department of Energy's CALiPER program writes extensive reports about the products it tests. Brodrick says consumers will get a lot of information from reading the first page of a report.

    LED lighting is awful for holiday lighting. Blue is the only color that shines bright. The Christmas tree in New York looked horrible the year they used this technology.

    I'm glad to be seeing LEDs used for more and more things. We just got two LED floodlights to replace our outdoor sensor light on the porch and it lights up very brightly. The auto industry ought to be using LEDs more for taillights and clearance lights, but I believe that will come soon. I'm already seeing them used for license plate lighting and some new headlight designs. Christmas lights will improve over time, but I do like the idea.

    LED lights still cost too much up front. The Christmas lights I saw from last year were all blue tinted, dim and expensive. This year I saw some brighter Christmas LED lights, but they are expensive. In a few years once the price for the brighter lights comes down I will consider getting LEDs. So I am still using my old lights until then.

    Yes but I don't understand. How just use the bad combination of led? Because blue is the most known but red too can bright so strong. And there are some green versions what bright strong too. So, we have at least: Red, green, blue. That can be combined to make the rest of colors and so bright. Who is manufacturing that bad led christmas lights?? That is not really so hard to manufacture a good one.

    I have all my lights as LEDS and with the amount of lights I use I plan to save a lot, the intial output was about 200 for all the lights on my house but with the savings I'll recoup the cost in about 5 years I figure.

    Working as a lighting consultant, I can say with certainty that the technology of LEDs is improving every day. The color is improving and prices are already starting to come down as more reliable products are made by competitors. Systems (undercabinet lights, cove lights, recessed modules) are still far superior to LED lamps (light bulbs), but they are really making strides.
