Here at Hydrobuilder, we have a wide selection of double ended MH and HPS ballasts for hobby and commercial growers alike. You'll find all the best brands here such as Galaxy, Sun System, Xtrasun, Phantom, NanoLux, and more. Even better though, we are able to offer you the lowest prices on the internet!

Whether you need a replacement DE MH/HPS ballast or you are piecing together your own HID grow light kit, we have the ballast you are looking for.

What is a double ended MH and HPS ballast?

A double ended HPS and MH ballast is designed to work with double ended grow lights. If you have a single ended grow light, worry not, we have those too! But these days, most ballasts are optimized for both SE and DE lights.

Just make sure before purchasing, so you don't end up with equipment that doesn't work. And when in doubt, give us a call, and we'll confirm the ballast is compatible with your lighting system.
