I like this fixture

The only thing I don't like is the 250 watt double end. Can I switch the ballast to a 150 and just use a 150 double end? Yes, its going to cost more but I'll get what I really want also. Please let me know your thoughts.

Thank you

So you basically want to use the fixture and change all the guts. If that is correct. Then yes it will work.

according to this:


they do not use the same socket, Rc2 vs. R7

I would do more research before proceding
