I have about 3-4 electronic ballasts ($25-$30each) laying around so yea I have the equipment. The fixture on one of my freshwater tanks has 2 40 watt tubes overdriven 4x... roughly 320 watts not including power lost to heat and age of tubes... have to wear shades
when servicing the tank.
For those that haven't heard of ODNO it stands for Overdrive Normal Output.
What it basicly does is tricks a 4 lamp ballast into running 2 , or even 1 tube producing more wattage from a flourecent tube (some is lost in heat, but nowhere near as hot as MH ).
I've been running them for years on FW tanks, they grow plants like crazy. For the cost, you cant beat it.
