Weird Lumatek Ballast

So I'm a noob and bought a Lumatek ballast for really cheap on Craigslist. Well when I got it home I realized it had this weird adapter on it that SHOULD be the place to plug my reflector into but instead it looks like a normal plug. It's called a Leviton adapter. wtf is this? how do I get a standard adapter on it? am I skrewed? and also since I can't plug it into my reflector Idk if it even works I dont hear any sound coming from it when I plug it in. Did I get ripped off? Probably so but is it possible to save it?

u can go to local hydro store and buy the plug you need. Open ballast and do a simple color-to-color wiring job

Thank you so much! I'll do that today and maybe we can see if it works before we do that! If it does then I got a 600watt for 35$ lol woohoo

it probably does not work for 35$..... but that is a hell of a deal if it does.

Well...the guy said he found it in his storage shed and didn't know what it was exactly so he might have just been lying to sell the thing. I'll find out today. If he did then ill be sending him a nasty email.
