Wholly cow thousands of lights out there.
I do know that I bolted from cali in 94, had water issues in 1980, wasn't allowed to wash you car, smokes and gas was twice yhe average price of the rest of the USA. you had to have 2 bedrooms for a baby by the age of 18 months. Didn't take an axe to hit me in the head.
So any testing done in cali beats most standards set. Cali sucked then and rolling blackouts, price of the watt at the meter, and fires. So glad we moved then.
Now I know two companies, still only recommend one.
Fluence, is another big player out of Austin, Texas. They do work with NASA and Dr. Bruce Bugbee.
Blackdog LED, California Lightworks, and others.
