anyone have experience with the grow light track from hydro farm?

or any other light track i guess. thinking of getting one for my 4x8 tent. are they legit? would it really act almost as well as another light?

 

I am useing a lightrail made by hydrofarm in a 6' by 8' room with a 1000 watt HPS light with out the light rail I would have to have another light a 1000 watts would not be enough. I was running the 1000 and a 600 hooked together and air cooled the 1000 does just as good with the light rail and I save on electricity, I done away with the glass in my light since im not using the air cooling any more and the glass made the light to heavy. I think its great.
