I used PAR of 300 and 10 hour photoperiod to calculate a DLI, and arrived at 10.8, which some be fine. Make changes to photoperiod slowly and watch your corals for any negative signs. The Radiums should generate good coloration and, yes, their PUR will be different from other light sources. Just how much of a difference this makes needs to be investigated, something I could do once the new lab is completed.
Thank you so much for the reply . It will be great if you can include of halides in your experiment just for us halide guys to know more into lighting .
