The U.S. Department of Energy Solid State Lighting web pages

I recently stumbled upon the U.S. Department of Energy Solid State Lighting web page and found some interesting information therein. Thought I'd post the link for anyone else who may wish to check it out.

I picked up a snippet of info that should be useful to others while browsing through that page again.

LED light output estimates (as reported on manufacturer datasheets) are typically based on a short (<1 second) pulse of power applied to the LED chip, with junction temperature held at 25 degrees C.

good to know.

Yes. The whole issue of standards and measurements is one of the things that caught my eye on this site. http://www1.eere.energy.gov/buildings/ssl/measurement.html
