I a 600w HPS from
cPanel
I have had it about 5 years and love it. When I was looking for a light and trying to decide on a size I was told that a 1000w was to bright unless you have 12' ceilings, the 400w well every body is buying 2 to give you 800w. So I went in the middle at 600w at half the price of 2-400w, and then someone gave me (yes gave me) a 6' light mover. So now I increased my growing area by 6'. Hope this information helps you decide because you will grow better plants and flowers under these lights. You might even want too look at the HPS/MH combination fixtures.
