The bulb in the kit will work with all kinds of ballasts but it is optimized for use with the "superlumen" 10% boost.
The Lumatek 400W included in the kit is a fully electronic ballast. It has 4 modes, 250/275/400/440W. So you can during the growth phase have the ballast on 250W or 275W to save on power, then put it on 400w when you start bloom phase for your plants. To maximize your harvest, you can "boost" the ballast up to 440W.
The kit includes:
1x Cool Tube fittings 125mm 49cm.
1x Lumatek 400W ballast.
1x Lumatek HPS 400 W Lampa
1x Cable for ballast and reflector.
