If you call Perry at Sunlight supply, he will recommend a Bluewave ballast containing a M135 ballast for the 400w radium bulb. This is the same ballast sold to Jeanna by Jayson for her 400w radium bulbs.
So the original post asked what was inside a blue box from Perry if running a 400w radium. The answer is a M135. That was the question, right?
