I purchased 2 of these MH Ballast today


this is the specification of the ballast

One ballast for all voltages

from 120V through 277V!

NAiS DCP™ (Dual Constant Power) Electronic

Metal Halide Ballasts for M148 ceramic,

approved M110 or equivalent metal halide

lamps (50 watt lamps).

This integrated unit replaces the ballast, capacitor,

and the ignitor of magnetic ballast systems

But as you see its 50W and there is no 50W Good reef Bulb

what i am thinking of

Can i connect these 2 ballasts in Series so that i can hook 100w MH Bulb? with the right color temp?
No. A 50w ballast will fire a 50w bulb. I wouldn't even attempt hooking them together....unless you have a firetruck on stand by.
