  Gordon said the competition has encouraged manufacturers to develop a new generation of residential fixtures that are attractive, energy efficient and appeal to homeowners.
  
  "Designs are evaluated on their attractiveness, value, marketability, innovation and functionality," she said.

  Can dimmers work with LEDs? - Lighting Designers -... - [Cached Version]
  Published on: 10/10/2008    Last Visited: 5/21/2008  

  According to Kelly Gordon of the Pacific Northwest National Laboratory, normal household dimmers work by turning the power on and off to an incandescent bulb very quickly.Because it happens to fast, most people don't detect that the light is flickering; instead it just looks light the light has been dimmed.
  
  These dramatic spikes in current are fine for incandescents, but Gordon says CFLs and LEDs both require very specific power levels to operate and often the ballasts and drivers that regulate power to the CFL and LED bulbs aren't able to withstand the pulsating power.
  
  For example, Gordon says some screw-in CFLs will work with the existing dimmer switches, but often when the lights get down to a 30 percent light level, they'll simply shut all of the way off instead of gradually dimming to darkness.
  
  The problems are even worse with LEDs because Gordon says some dimmer switches have a minimum load requirement to work, and when those dimmer switches are hooked up to the extremely energy-efficient LEDs, the dimmers won't work at all."[Sometimes] they'll have a 100-watt minimum load that they'll work on.And LEDs are starting at already way below that, so even if you had a bunch of LED fixtures on it, it still wouldn't meet the minimum load requirement for the switch, so that's another challenge," Gordon explains.
  
  Luckily, CFL manufacturers are now beginning to specify on their packaging whether the bulbs can be used with dimmers.But Gordon says most LED bulb manufacturers haven't begun to inform consumers about whether or not their light fixtures are compatible with exisiting dimmers.
  
  In fact, Gordon says she's only aware of one LED manufacturer, Cree LED Lighting Solutions, that specifies which company's products are compatible with its lights.
  
  "I think, as we see more LED replacement lamps, [or] screw-in lamps, that's something manufacturers are going to have to do.They're going to have to give an indication of what kind of dimmer switches their product will work with… They're going to have to label them as dimmable," Gordon says.
  
  Over time, as LEDs become more common in residential lighting, Gordon says more LED-compatible dimmer switches will be installed in homes.
  
  "But that's going to be a long-term thing," Gordon says.

  Kelly Gordon, program manager for the project, said the biggest hurdle to builder and consumer acceptance of dedicated CFL recessed lighting is their availability and expense.

  "We added the SSL component this year in response to very rapid improvement in LED technology over the past year," says Kelly Gordon, Program Manager for the Dept. of Energy's Pacific Northwest National Laboratory (PNNL)."Luminous efficacy [the amount of light per watt of electricity consumed] for LEDs has continued to increase remarkably quickly to the point where the higher-quality LEDs are now as efficient as CFLs for certain applications in well-designed fixtures."
  
  LFT chose four victors from the more than 30 entries submitted for the 2006 contest.The winning designs were showcased at the Dept. of Energy's Solid State Lighting Workshop, held Jan. 31-Feb. 2 in Phoenix.
  
  "We were pleased with the response, having [received entries] from a range of companies, including [both] well-established fixture manufacturers, as well as new players," Gordon says.Congratulations to the winners of the 2006 contest:
