I’ve grown with china bulbs I had two same exact hoods one China one hortilux your crazy if you think the China was even close or kept the same brightness after a week of use!
Who said anything about China in the first place. Better yet, who cares!
130.00 bucks for something that only gives you (at best) 10% more PAR.... Now look at cost of 1 of several brands, at less then 27.00 per bulb.. (buy in bulk for less! Get a business lic.)
You can NOT tell me that spending over $100.00 more per bulb. Gets you any better cost effectiveness.
I gotta tell you with my OWN light meter. I only got 7% better PAR.
I have run Green Houses and dealt with lighting issues, Possibly before you were born.
I have NEVER gotten a bum bulb from my supplier. They tell me if I'm not happy with any they send. Send it back for a new one!
EYE Hort has the same damn bulb warranty as mine do, and are
completely effective!
AND....I don't have to Bull Shit about the bulb delivering 4-5 extra zips a run!
THAT SIR, IS BULL SHIT of the first order!
Don't even bring up EYE's claim of being able to run 1 extra run! This is not true by my and others test's. They degrade at the same if not more of a rate then my COMMERCIAL bulb's!
My straight HPS hoods deliver 20% more light energy to my plants then yours do too.... To bad you can't get them any more.. Jupiter 6's.....
Bottom line:
Having done the math and the testing myself. In green houses and my op's... I get more for my dollar.
You didn't list the brand of the "china" bulb either..... FAH.
