Looking for a compact MH ballast for my aqua-medic fixture. Ideally I need a 150w hqi ballast. Like
this one. Dimensions around 5" x 3.5" x 1.5"
Problem is it needs to fit inside the fixture, can't be an external ballast.
I would be interested in higher wattage, but I would need two then. Otherwise if 150w I just need one.
Thanks
Matt
