ok i wasnt sure if the ballast would run a 400 hps on the dimmed for some reason, i dunno.
Got the lightspeed hps today hooked up real quick to make sure ballast was not faulty, Works Gr8 Looks bright so far.
Another question, i need a hood or cooltube, not sure about cooltube as i would thinkg u would loose length footprint and have anice wide one though, anyway for now i have Batwing the surface above the bulb is flat no "difusser" i think it is called, will that kill my bulb should i add a crease in the middle?
Thanx for all the help peeps !!
