Based upon the PAR data for the other Ray2 fixtures it seems like a reasonable bet that this fixture is in the 40-50 range at 12" depth. The 16" fixture is 49 mmol at 12" depth and the fixtures tend to increase in intensity at somewhat regular intervals as the fixture size increases.

Probably a bit more light than you would want for low tech but if you are planning to dose EI and Excel then you should probably be able to manage algae.

This is speculation, obviously, but you seemed like you could use some reassurance.

If it was my tank (and I have a 12" cube tank but I don't have an LED fixture on it yet) I would not be too worried.
