I was thinking about going into using one of those combination luminaire with 1 MH light and 2x T5HO light. However, as I'm intending to setup the unit in singapore, heating becomes a problem due to the temperature the unit produces. Can I use a 2 feet unit over a 3 feet tank but raise it up higher? Maybe around 12-18 inches height above the water level?
The tank I had in mind was a 90x45x45 and the option available to me is either a 150W luminaire with 2x 39W T5HO or 1x 150 with 2x 24W. Judging at the power of the MH bulb, I'm guessing that it make no significant difference in terms of lighting power but 3 feet unit might have a better coverage due to the 39W bulb. However saying that, the 2 feet unit produces 198W light over 180L tank, which is pretty intense and hanging it 2 feet above the tank should have provide enough coverage and yet provide enough light for a high light tank right? I've not use MH before hence the stupid sounding question. I would appreciate if someone could enlighten me on this issue. thanks
