I have 2 lumatek 400W MH/HPS digi ballasts that have not given me any problems thankfully. Both currently have HPS bulbs not sure of the brand I'd have to check the box. Got 2 400w aircooled setups on ebay for 220 each brandnew and I've been happy with 'em so far. Best of luck with your new ballast.

Well actually now that I think about there was one thing weird about them, the socket cord would not seat into the ballast. Upon visual inspection of the socket on the ballast where the output is it looked like one of the slotted connections was over soldered? I took an eyeglass type screwdriver placed it in the slot and tapped lightly with a hammer. Now the plug seats fine and no issues since.
