Hey guys im setting up a new cab and am running a cooltube with a MH bulb and ballast. When i bought the cooltube the site said that it worked with MH bulbs and ballasts but upon opening the box i fond the the cord leading to the ballast is for a HPS. So now im a bit screwed. I have MH Ballast cord can i splice the cord with the MH fitting. I have done wiring b4 so actually doing it is no big deal i just want to make sure my house wont catch on fire. they both have a positive negative and ground wire so cant i do this? Thanks guys....
