i have 2
MH ballasts for sale right now !! CHEAP (for TR only $70) !! then all you would need would be reflectors ($30), sockets($10), and bulbs (depends on which bulbs), but i can throw in a couple of XM 10k bulbs with the
ballasts until you decide what you want to go with). you could have a nice
MH setup for about $220 after you buy the above items.
