LED's ? (Kind or California light works

thoughts on these 2 LED’s

Kind L4 - L450)
California light works Solar System 550

both are about the same price $700.00 (+/-)

any information is greatly appreciated - Thanks (leaning toward the California brand, was sold on KIND until ran across this one)


I haven’t seen ppf on kind, but there’s probably a reason for that. The California lightworks model is listed at something just a little shy of 900 umols I think and over 2.2 umol per joule. If you were down to deciding between the two, I’d go with California lightworks.

When you look for competitors with that kind of efficacy, horticulture lighting group, timber grow lights, chilled led, fluence, and I think I read that the newest spectrum king light is finally there too.
