coralife M/H ballast question
 

1 of my 150 watt ballasts keep shutting down and im just curious if i would have to replace it with another coralife ballast or if i can use a different brand as i cant seem to find a coralife one. ( are the plug ins all the same )

Coralife units have a MH starter embedded in the light fixture. So, unless you open it up and do some rewiring to bypass the starter, you'll have to find another Coralife ballast. I went through that when I upgraded my coralife light fixture from 3x150 to 3x250 watts.

I phoned J&L when I needed mine replaced. They don't list them but do have them.
