yup, id just watch how fast you increase intensity.
an estimate.
20k lux/60(constant)=333par
37k lux / 60 = 616 par.

so.......3,000 is 50 par.

So maybe my 85% is sufficient with angling the light more directly at the sps. I am not unhappy with the sps just trying to give them what they need.

light levels are entirely up to you. My only caution is to adjust them slowly.

Re-took some lux readings at max intensity of 85% on the A360 and got right around 20,000 right under the light. Where the sps are positioned it was closer to 15,000. I turned up the 360 to 100% and am now getting 37,000 give or take a few thousand depending and angled the light so max output is more where the sps are positioned.

Is this too much? 100% intensity (for 4 hours currently I think) in the light cycle on a BC29 seems too much...
Hey how high above the meter is the light please?

I'm estimating the light is 12" off the surface of the water. The meter is held as close to the water surface as possible. So...10" or so probably.
thank you. I collect par and lux data on lights. Thanks for the help.
for what its worth, I believe your light has very close to the same power as an ap700.

I ended up bumping the schedule back down to 85% max intensity. For what it's worth, the readings were taken at a max color of 60% also. As, if you are familiar with the Kessil, it's just a percentage from 0-100%, blue to white respectively.
