Q for the MH retro experts

[Cowtownman]

I have a standard 58 gallon Oceanic with the manufacturer's canopy. Retrofitted into the canopy is the CSL 4*96 watt PC lighting system. I would like to add a MH bulb, maybe 150 or 175 watts and was thinking about an HQI double-ended type. Who makes a good system that can fit in a 4 inch canopy and reside a few inches from the water surface. I have 2 big cooling fans so heat is not expected to be a problem. Thanks.

Both PFO and Sunlight Supply make nice HQI pendants which would fit in that canopy just fine.
Assuming you are keeping your 4x96W PC's 1 or 2 dual 150W 10K HQI would look awsome.

Thanks. I figure that this thing will be 2 inches from the water surface. It will have a UV lense, so splashes won't hit the bulb. Other than maybe limited light dispersion and heat build up, are there any disadvantages I need to be aware of?
