SB Reef Lights Opinions

[USMA36]

Correct. It’s 30,000. By about 50.
Only about 600 par. So no. Def not too much light.

The fall off on the edges is normal.

Fwiw, the true actinics are the Lowest par and output bulb. As they produce a very narrow band of light.
About half of a blue plus I belive, so you’re par may be a bit lower.

With those numbers , use SB’s lighting schedule and use the peak lux as the new peak of the photoperiod. Reduce it for acclimation for a couple weeks.

Sb fwiw, uses a very long viewable time ,like 12hrs. Very low intensity am Pm, with a six or so hour peak.
Mine was more like 13 hrs.

Thank you!! Is there a way to figure approximate par at different levels of the tank assuming clear water 24” deep? Or is that asking too much without a proper par meter?

As above , you can look at the Milwaukee submersible , or put the cheap one in a zip lock bag or water proof bag.
