Which grow light? Looking at a Vertizontal reflector

Hey guys,

Need some advice on a grow light now I have seen the light (pun intended) and have decided to move on from a CFL set up of 1 300W and 4 30 watters to a 600 watt while retaining the 30w cfl's to get close in.

Been looking at the Vertizontal Reflector as it is 115cm and my grow room is 1.2 x 1.2 so fits perfectly and looks like a lovely piece of kit:

Or do you think I should just stick with something more traditional like a Super Nova?

Don't mind spending money on the set up as all I want is some quality bud. To give an idea of size, the tent is a Secret Jardin DR120 and my grow system is a NFT system approx 1m by 50cm growing 6 plants in. Don't want anything aircooled either as the tent is in my uninsulated garage so needs some heat from the lights.

Thanks in advance guys and look forward to hearing from you

That first one is meant to distribute light over a much more broad area, the other is more focused.
