So I have a general lighting question I have a VB luminaire series by hydrofarm 1000w ballast and matching hood. That I bought used off of craigslist. The Ballast says its for HPS says nothing about MH. The guy I got it from said he was selling it for a friend and that his friend never really used it. just to start his outdoor plants inside using a MH bulb.
It came with 2 bulbs One Mh (the one I tested with) and a HPS that wont light up.
The problems Im haveing is it wont light up the HPS bulb only the Mh one.
After being on for about 15min the MH light dimms down. Doesnt go out just dims down what could be the prob be?
So im not sure if the ballast is broken or if the bulb is. the man said the HPS was never used only the MH.
how many volts at the socket should my multi meter read. I did try to test it yesterday. I think something is broken inside the ballast put out like 210 volts and dropped slowly to the 180's. I tested it with the meter set to ACV....
