Aye, I'll keep you posted.
Be interested to see how them 600 cmh work out too. I never knew they existed.
Think the issue with some of the cheap digital ballasts is they don't run as hard as they say.
I had a 400 I was using for veg and it was only drawing 360w , which fired up a hps bulb buy not a MH.
I tell you what, there's a massive weight difference in the ballast when you compare the likes of maxibright, omega , lumii to the quality of lumatek ballasts.
Also maxibright and lumii are now making LED fixtures which seemingly run off the digital ballast HID ballasts too. Which is a bit weird.
