I have been using a Lumatek 400 watt digital ballast for a couple of years, and have nothing but good to say about it. They have five-year warranties, which is the best I've seen for any digital ballast. They also now have 120v versions all the way up to 1,000 watters.

Choosing a Ballast So I am getting ready to start building my first cabinet and I have been looking at Digital Ballast that can recognize either HPS or MH lights. Just wanted to get the communities opinions on digital ballast and maybe what brands to go with. Rating: 5
