My lights are 2 - 175 watts MH Coralvue Reeflux 10K and two VHO 72" Universal Lightning URI 160 watts each, one super actinic and one actinic white.
The Reeflux are extremely bright with a very nice white color. They are excellent for photography. I used to have two Coralvue 12,000K MH that were not that intense.
The combination of the MH with the VHO makes the correct combination for growth of the corals and the look of the colors.
