Yeah, I bought some lights (3 of them) from inside sun.
Use the search function on the forums... there's a lot of info on the company..
I was broke as hell back then and I won't buy from them again.

-Cords are not removeable, very difficult to set up your ballast and lights in separate rooms as many experienced growers prefer to do
-the 'econo' reconditioned ballasts... meh... mine looks like it came from a fire and runs so hot that you can't touch it for very long
-actual ballast-to-bulb cord is NOT grounded ( I did a dissection, lol, and was a little worried at that).

But they work. And they are cheap. I don't regret buying from inside sun, it's a good site for us broke-ass mofos.
