I prefer lumatek but it's a little expensive.I'm confused.Please help me,thanks in advance.

Non of those..

So what's the best ? I just use a 600w hps no more..

anyone ??

Lumatek

get the lumatek

I would not go with lumatek. When I first searched online for the good brands lumatek popped up everywhere but you'll soon find some people have nothing but problems and some never have a problem. Lumatek is the common brand sold in stores as well, so more people will chime in about it than any other brand.

The best consumer digital ballast brands right now in my opinion are Solis Tek, Quantum and Galaxy. That seems to be the consensus across the board. I went with Quantum.
