Any one have some input on a good lighting setup. I just purchased a all-glass canopy for my 110g the problem with this canopy is that it doesnt have anywhere to mount a retrofit on the top because it has the sliding door for feeding. So my question is would i be able to place a regular metal halide fixture or does it have to be a retrofit. Was told i needed a retrofit because i would burn out a regular fix with all the heat it produces.Needed one with the external ballast. Going to have to figure something out with the retrofit.
