Another post on LEDs

1 June 2009

The Star Trib published a neat little round-up on LED (light-emitting diode) lights this weekend that, in my opinion, does a good job of covering the basics of the next generation of lighting.  The benefits of these new lights are obvious and far-reaching:

Studies suggest that a complete conversion to LEDs could decrease carbon dioxide emissions from electric power use for lighting by up to 50 percent in about 20 years. A recent report by McKinsey & Co. cited conversion to LED lighting as potentially the most cost-effective of a number of simple approaches using existing technology to tackle global warming.

And yet, let us not forget that they are still in development and have their own issues that really matter to American consumers:

Still, there remain significant barriers to LEDs. Homeowners may balk at the high initial cost, which lighting experts say currently will take five to 10 years to recoup in electricity savings. An outdoor LED spotlight today costs $100, as opposed to $7 for a regular bulb.  Another issue is that current LEDs provide only “directional light,” not a 360-degree glow.
