both set ups are on work horse ballast

my tank is a 180g 6*2*2 i run 8 4 ft t5's and 2 4 foot vho's (which are in the center ) the lights are staggered one bulb goes fully left and the other goes fully right and that’s with all 10 bulbs.

You can see the light difference on the sides with par meter but its not visible with the naked eye IMO.

The light numbers on the very top were with the light meter being directly on the bulb.




vics tank is only 12 inch’s deep but i ran SPS bulbs on hers because they were cheap and you can really tell a difference with the numbers. another variable is that i run tek 2 reflectors and she runs glo reflectors



sorry it took me a while to post these results just have not had time to do it
