In doing my research looking for a hps to flower with, i came across the problem, which reflector shape should i get? there are all different kinds, but which maximizes the light output? Here are a few options 1) Parabolic 600 HPS Parabolic Grow Light System | BGH 2)Round Reflector 600 HPS Round Grow Light System | BGH 3) Horizontal "rectangluar" reflector 600 HPS Super Sun 2 Grow Light System | BGH Which is best?????
"Best" kinda depends on your setup but i think regardless id go with #3. Parabolic reflectors were designed to direct heat to the center in order to allow for easier venting. choice #3 is a vented reflector so it will cool more easily than choice #1. Choice #2 will actually give you the least light coverage. It burns in a vertical postion so lumens will be primarily directed to the side not down. Choice 3 will give you optimum light coverage and the easiest means of cooling your lights. I think you will be quite happy with it despite its bulky size. The price of that light though is a bit much. I recently bought a 400w nextgen digital ballast, with a cordset and it was only $270 I use a Sunleaves Aurora Six reflector(basically the same as choice 3) and i got mine at my local shop for only 60 bucks. If your getting a basic core and coil 600w should be able to get a whole setup for like 250 maybe even less.
I use # 3 but with the Sun System 1 ballast. ~ $450 - 475 at avg. grow store prices by the time you include a bulb. I'm well pleased. (I only buy Sunlight Supply ballast) Peace, SlackerBee
