Hey Guys,
I have a 400w MH Hydrofarm light system, I would like to swap it to HPS as I will be using CFL's for veg. Will this unit handle a 400w Hortilux eye HPS bulb?
No the bulb type is specific. Look on Amazon for that model number and see what it returns. You do not have a switchable ballast to run both MH and HPS.
