Mars SP250 dimmer

[HigherTheHigh]

I'm running two SP250s in a 3x4 tent and I'd like to dim them both down to 200watts each, I don't want to touch the ballast at all as I know you can adjust them apparently from there but if I can add a dimmer to it that would be so much better.

They come stock at around 200w if you haven't touched the dimmer on the ballast

They are 230-240 mate
