So for those of you that have the Giesemann 14.5k Coral Megachrome, what ballast are you running these with? I'm trying to decide if the Blue Wave 7 or the PFO 250 HQI is the way to go (both are M80 I believE). Either way I'd be using a Dual ballast (the ones that are set up to run two HQI Bulbs). Are there better ballasts out there for these bulbs?
