Yep. I have had real good luck with this lamp and ballast. One thing I would reccomend is to pay for the bulb upgrade. The cheap bulbs that came w/ the kit blew 3-4 times. Both the MH and the HPS. thankfully HTGsupply sent me the upgrade bulbs(agromax) at no extra charge. They did replace the bad bulbs each time though. So if you are looking at buying from them I say go for it. I am very happy overall.
