I have had my Current USA Orbit 48" MH light fixture for 13 months now. Tonight I came home to find only one of the actinics on (out of the 4 actual tubes in the unit). Good thing, I'm thinking because I recently bought new bulbs. However even with the new ones I am having the same issue. I believe that a ballast has gone bad after 13 months. Go figure, as the warranty is 12 months. Has anyone else had this issue? Any suggestions? TIA.
I believe that there are at least two separate ballasts (one for the MH's and one for the Actinics), if not more. I didnt want to dig too deep into the fixture while I was changing the bulbs last night. The LFS thinks it is a ballast issue as well.
