I know they are the same type of light,as T8 and T12 floros are,but I didn't think you could interchange the bulbs between the different ballasts.
Its white Light,
Its the kind of Fixture you would see in a CVS or toys R US.Very Big and bulky,I'm going to take the socket out, run a neutral and power line from the ballast and put the bulb under a DIY reflector.
So the white light is considered MH?


Its actually a 400W
You know I think you are right,I was thinking of bulbs.
