$20 LED "bulb" breakthrough ??
Bridgelux had a nice write-up yesterday in Green Venture Beat. The article entitled "Light bulbs are so over --- Bridgelux brings LED lights down to $20" leads us to believe that high performing, affordable LED general illumination light has arrived.
Unfortunately, the article fails to to mention that the $20 "light" is not actually a bulb. It is only the LED "module" - that will require one of 15 approved power supplies - that need to fit into one of the approved fixtures that will come eventually from one of 200 fixture manufacturers - primarily targeting retail and commercial applications.
The idea that you can swap out a defective LED is novel. But if a benefit of LED lights is that they last 30,000 - 50,000 hours (using DOE/EPA usage standards that translates into 45 years) then one would wonder why you would need to replace an LED module?
