Oh how I have waited for someone to ask a question about VHO
`s. LOL. It`s all I have ever used. I love VHO
`s and would not deviate from them. Saying that, the others are right about T5HO being better. But still I just want soft and LPS
corals and VHO
`s will fit the bill for that. As far as a lighting unit there is this
VHO Aquarium Lighting: Hamilton Magnetic SuperPower VHO Systems
I do mine retrofits. I run 4 - 160 watt bulbs on two ballast. The bulbs have internal reflectors. I also have a reflector dome over the bulbs to catch most of the stray lighting. Here are some pics of my lighting that I have had for 12+ yrs now.
