Lighting question before i purchase

Finally time to upgrade my lighting, I have a 90 gal mixed reef system,which i currently am using a 2bulb t5 fixture paired with a 4 bulb pc system.

im looking into getting rid of the two sets and replacing with a Tek Elite T5 setup. My question was which of theese 2 setups would i need, I'm thinking the 6 bulb http://www.reefgeek.com/product/48_...ixture_w!_Bulbs_(Graphite)_by_Sunlight_Supply but will it be overkill? should i go with the 4 bulb setup? http://www.reefgeek.com/lighting/T5...ixture_w!_Bulbs_(Graphite)_by_Sunlight_Supply
and also which bulbs should i get with them?
1 more thing i read somewhere here about a 15$ fuge light from home depot , anyone remember what light fixture/bulb that was?

 

If you are going SPS dominant then the 8 bulb fixture is what you need, other wise I would suggest the 6 bulb unit.

I think on the fuge light it is a cone reflector with a spiral compact fluorescent bulb.

 

90's are deep so +1. 8 bulb will do the trick for anything u wanna put in there. with 6 you would still be fine but it would suck to have to upgrade incase you go SPS dominant. still, 6 bulb would cover 80% of situations, 8 bulb is 100%. that % is completely made up so please don't ask for sources =)

 

thanks im only gonna have a few sps so the 6 should be perfect then

 

sounds like a plan! GL buddy, i wanna see pics when its up!
