• LED Traffic Lights Cause More Accidents in the Winter! [DESIGN FAIL]

  
  zedomax.com — Authority: 545
  Apparently, the new energy-efficient LED traffic lights proved to be fatal in snowy areas as they don’t have enough to melt snow, making the traffic lights un-usable. …unlike conventional incandescent traffic lights, they do not generate enough heat to keep themselves clear of snow, and thus can easily become ...

• Maybe LED Traffics Lights Weren’t a Good Idea After All

  
  ModCool — Authority: 158
  Installing LED traffic lights may have sounded like a good idea when first proposed -- after all, LEDs consume 90 percent less energy than the incandescent bulbs being replaced -- but some city planners who made the switch are now wishing they could take a mulligan. Why? Apparently the bulbs just dont burn hot enough ...

• Energy-Efficient LED Traffic Lights Are Backfiring — Deadly Results For Drivers

  
  Tarpon's Swamp — Authority: 136
  Many people have died, as the dysfunctional traffic lights just don’t work in snow. Looks like the old hot bulbs might have been best after all — It now appears that old fashioned, power hungry incandescent lights have one major advantage over LEDs — they get hot enough to melt snow. Unfortunately, cold weather ...

• Law of Unintended Consequences: LED Traffic Lights

  
  GreenEnergyForEarth.com - Solar & Wind Power Products — Authority: 126
  Dec 16, 2009 – What can go wrong with LED traffic lights that use 90% less energy by producing less  heat?  There is such little heat produced that when there is a snow storm and the snow is that particular “sticking snow”, it covers over the traffic lights and there is not enough heat to  melt the snow and ...

  Jalopnik — Authority: 758
  New-fangled LED traffic lights last longer, pierce the darkness more effectively and consume 90% less energy than incandescent bulbs. Thats also their drawback. Theyre not hot enough to melt snow that sticks to their lenses, causing dozens of accidents. LEDs are, by design, more thermally efficient than ...

• Yet another downside of being green

  
  Bookworm Room — Authority: 639
  The law of unintended consequences is a fascinating one.  I blogged the other day about the tax on restaurant food that’s eaten “here” as opposed to “to go.”  In cafes, smart people order food “to go,” and then consumer it here.  The result is garbage cans filled with food containers.  Oy, the ...
