I replaced 4ea 96 watts PC and 3ea 250 watts MH with 52 white XP-G and 96 XR-E blue. This is for a 150 gallon 6 ft wide tank. It is so bright that I can't have all the white one at one time.
The tank runs much cooler, chiller is not over work anymore.
PM me your e-mail and I can forward som picture to you.
