If its 4 bulbs, I'm assuming 2 bulbs per switch? and both bulbs on 1 side aren't turning on? and is it 65W per bulb? or 96W per bulb? They require different ballast.
it's 65w per bulb. it's a JBJ model. Yes, there are 2 bulbs per switch. And yes, there are 2 bulbs not turning on vertically (meaning the lights are not adjascent to each other.
