Lumatek Dimmable Digital Ballasts are a great choice of lighting for your hydroponics garden, offering much more control with your light from one ballast. These ballasts produces up to 30% more light output (lumens) than standard core and coil (magnetic) ballasts while drawing less electricity. Test data has shown that a Lumatek 600 watt ballast produces only 5% less usable light than a 1000 watt "core and coil" ballast.
