So i currently run ushio se 400 watt 10k bulbs on m59 ballasts with luminarc large reflectors over my 180 and enough is enough. While no one is ever happy with halide colors I "gave in" and just dealt with the overpowering crystal white these bulbs throw. BUT now the Bleaching is starting. As stated they are in luminarc large reflectors and the height of the bulb is 21 inches above the water line. So I need those running 400 watters to come forth with some bulb suggestions that actually will DROP intensity and most likely PAR. I supplement with 2 uri VHO actinics so maybe that helps. Ran xm 20k and they were too blue, reeflux 12k need not apply, what a waste of electricity there. So any advice? And no, water temperature has never been a problem so no addition to the Bleaching problem. Stays at a constant 78 degrees with lights on or off, it is just these plasma cutter bulbs i have.
