lumatek and another are top dawg
im using a knockoff with no problems
they actually use less power than traditional magnetic ballast
can use both mh and hps bulbs, not conversion bulbs
about half the size of traditional magnetic ballast

they are worth it in my eyes
texas grass Reviewed by texas grass on . Which ballast and wot manufactor? Hi- Opinions on digital ballasts and the usual coil style please, would like to know if there are good savings to be made with digital as apposed to coiled? Do the digi's last longer? Do they screw more outta the light bulb too? Do they cost less to run? Anything I should know in order to help me weigh up if its worth buying a digital ballast. Also, which manufacter in your opinion supplies the best ballast? Cheers Rating: 5
