My stuff is old, I keep repairing lights and my stash of old 500W qts are too maintenance intensive and costly. I need some lights for stands, I should have 500 style and some smaller one with 250 or 300.

I like these. A lot.
Very sharp clean cutoff lines.
Wiring, you'll need to know. Brass= brown
They must have shorter years in China.I bought a couple led work lights at rural king. Mounted them in place of the arm burners on the stand. Work fine.

It's an OR statementor those Chinese just can't do math.
probably a lot of assumptions in that math. Not sure what your math is.
6hours / day * 5 work weeks a day * 52 weeks per year * 21 years is about the same as 30,000... either cause I never seen bulb that actually meet that life span no matter the COO....
I typed about 600 words as to why. I deleted it because it was an education in nothingness and a lesson in futility.
Short version:
Marketing wise 240 days is a work year. The math comes to 30,000+.
Marketing and logistics and ethically determined usage shows they actually shorted themselves a month or two on their 21 year claim.
Thanks for bringing it up.
It's pretty standard.
(minus sick days, China is a 250+- day work year. With sick days they are at our same 240.)
So weekends don't qualify as "days". OK. Didn't mean to waste anyone's time. Apparently I just don't think that way. Unless otherwise stated, all days qualify as one day, any other creative esoteric interpretation is unethical advertising.
