I have 2 of the Hagen GLO prewired t5ho ballast that are 2x24w or 2x39w that I am no longer going to use, these have been used for a total of 5 minutes to make sure they work, I was going to use them in my new tank build but went with 250w metal halide instead. These are $54 on J&L but I will let them go for $40 each or $75 for both. Same ones seen here
