8 Lighting Relay Ballast Maximum 8000W Grow Light Controller for Hydroponics Indoor Double Ended Grow Light and Grow Tent Growing

Works as advertised. You will want a professiional electrician to install this item for you. Slightly loud at startup, but it's a high voltage item, so this is to be expected.

Works great

I was looking at Spartan and ran across these decided to give them a try. They are identical to the Spartan ones inside the front logo is all that was different and the Spartans higher price. ... hooked them up and they are great. Thanks

Love it! Highly recommended.
