L/F Ballast for my lights

[lapdog2020]

Looking for M80 Ballasts for my lights. I'm just not having any luck with this lighting thing at all.
I just bought a used fixtuer for my tank and now I found out that the ballasts are no good and i can't find the replacement for them at all, there an internal ballast in the fixtuer. So now I have 400watt lights over my tank that sit roughly 6 feet off my tank, thay where for my new tank that i will be getting in the next few months, But for right now I really need to get this fixtuer fixed. Does anyone have any Idea or have M80 Ballast for sale?

if I can't find this ballast I might be shuting down my tank. the 400watters are just to much for this tank. And the light is killing me when there lighting up my hole house. lol.

JUST GOING CRAZY NEED HELP! I'M WILLING TO BUY,BUY,BUY IF YOUR WILLING TO SELL, SELL, SELL.
