I'm not shocked by this as I have had a PAR meter and spectrometer for a long time and I did my own independent testing a long time ago.

Cool. What size aquariums do you have the light over? Do you have SPS in the aquarium? Where? Thanks for jumping in inwall.  |
Typically over a 400 gallon acrylic tank that is 26 inches deep. I experienced the same thing that Yellowbelly did, newly arrived brown SPS colored up quicker. The already colored up corals seemed to have more intense coloration but that is obviously highly subjective. (I regularly order in browned out SPS because they want to get rid of them quickly and I know that I can color them up which increases profits susbstantially). Planet Reef doesn't have one right now as people keep buying them from me used. The lack of heat is very nice in my situation. To give you an idea, yesterday it was 25 degrees outside and all of the lights in my shop put out so much heat that I don't even turn on the heat in the store.
