So close! Best light system for the money? (600w HPS/MH)

The title pretty much sums it up. I can afford one light and would love your opinion on which is the better system for the price!

Spend a little more on a Lumatek and don't skimp on one of the most important parts of the grow.

i agree 600w lumetek is awsome...i got one now i have 4....lumetek did their research well and designed an amazing ballast...2 years and no problems yet...be sure to get a digital specific bulb...the digital startup kills the high end hotilux...

Id go with system #2

worth the extra 10 bucks or whatever
