I have been asked if these PAR meters will work ok for reef tanks. To find out, I bought a 50-50 36 watt PC bulb, and tested a couple of them with that. One read 32 vs the Quantum meter reading of 33, and the other was only 2 units off at about the same reading. So, now I know they do work with 50-50 white/actinic light.
