I have no idea...3000K for 60k lux is 1142 ppfd, using that calculator....you might see some burn at 1142, less likely w proper acclimation at 962...so, you’re closer to 962 than 1142, i’d go with 3500K until you get better info...

Calling @Randomblame: any comments

Hmm! When the dividing factor is ~69 for 3000°k/CRI80 60klx would be ~870μMol/s/m² and with 70 for 3500°k its around 857μMol/s/m². This calculator is pretty useless because it does not factor in hanging height, area and all that. It also weighted to give their own product much better results. But CRI90 can not reach more μMol/s like CRI80 unless you compare calculated YPF/w values or older less efficient diodes. If CRI90 would be more efficient like CRI80 we all would have used CRI90 from the beginning.
I would not trust this tool.
The 60klx is also only a point measurment and shows only the intensity at this spot but not what is available for the whole plant/area at different hanging height.

Try this one... Simply enter the calculated lumen output, spectrum, area and hanging height into the according fields and tap calculate. Nice tool to play with..

Works much better and works with white and monochromatic diodes BTW. But not at the same time.. You need to calculate additional mono's separately.

I have lx and FC on my meter (Dr. Meter LX1330B). Clue me in on converting that to lumens? In the meantime I used 130 for watts (my HLG120H-20B at ~110% when run wide open (w/o the pot))

I used 1.5' for Length (the chamber is 17" x 21"-ish)

Beam Angle at 30 ok?

Now does it pass the smell test? Any suggestions based on the result? Screen Shot 2019-04-28 at 6.00.13 PM.png
