Not sure if this has been posted before, I think it has, but I could not find it...


Starting next year, the Federal Trade Commission plans to mandate new labels for all lightbulbs, modeled after the nutrition labels on most packaged foods

Picture goodness

Finally proof that Watts don't really mean anything anymore. Hey, even the FTC finally got it and they're not know to "turn on a dime" it's a big boat to steer, so this labeling is overdue!

It would have been nice to also have PAR on there... But some info is better than none, so this is nice. I don't know if it would be possible to approximate the PAR output of a bulb by knowing the amount of lumens+color of the light. Humm.....

/Yay for the new website logo by the way

I think using about 60 lumens per PAR will work, so 13.5 micromols

Any ideas on how badly that would skew with color temp changes to the bulb? I know you can have lots of par with blue LEDs that seem to barely illuminate anything to the naked eye. I'm not entirely sure how that relates to Lumens though.
