Do I need a glass cover for my Metal Halide Lighting?
I am installing a 250w metal halide light in my hood. I want to fabricate my own reflector. I have seen a few reflector projects online and one of them mentions tempered glass to block UV radiation so I don't kill fish and coral. I have only seen this statement once. How important is it that I have the glass? Another option is to buy a halogen light, gut it, and put my metal halide bulb in it. I like the idea however, I am not having any luck finding a halogen light large enough to will fit my mogul socket and bulb ( Iwasaki MT250DL ). With the bulb screwed in the socket, it is almost 11 inches long.
Any feedback would be greatly appreciated.
