Thinking of purchasing this for my future 75 gallon standard dimensions.

I will be using Co2 and EI dosing so as long as it stays in my budget(less than $200), the higher out put the light, the better.
As you can see in the link, the fixture's pictures show that it has individual reflector for each bulb.
Consider 4 bulbs may be enough but 6 bulbs sure cover the whole tank as its 20" wide on the 6 bulbs fixture (while the 4 bulb is only 14" wide)
Have not found much review on such fixture so thought i should ask
