Exactly., It works. Seriously, just ignore SlingingPAR. That's just a troll who keeps switching nick after people figure out he's just trolling here. He starts with a new nick so people don't immediately dismiss his nonsense.Ok gotcha on the lux thing. I still think it will give you very close to the umol output though, for example if I used the 0.014505 rate for 3000k samsung lm561c with 40,000 lux I get 580 umol/s but if I use the 0.014240 for a 3500k CXB3590 i get 569 umol/s. Same with 80 cri vs 90 cri. A few photons isnt going to make a big difference. I think using a subpar PAR meter will give you vastly different results (like the hydrofarm one). Again, the lux conversions im using are taken using an integrating sphere.
Although I do think the Hydrofarm par meter is a decent one though. Some tests seem to indicate it comes reasonably close to a proper PAR meter like a Licor.
Still, who cares about exact light intensities. People grow weed under anything from 250umol/s/m2 to 1500umol/s/m2. So who cares if you measure or calculate 800 or 880?
