Lumatek Digital Ballast 400 watt (Dimmable)

More light equals more yield! The Lumatek Electronic Ballast 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. Digitals do not degrade and will maintain their efficiency throughout their entire life. Over time magnetics become louder, produce less light, emit more heat and use more electricity.
