T5 Lighting

Im looking to upgrade my lights to T5 HO lighting, but i have a couple of questions on what i should get. I have a 6' tank and all the light fixtures are 4' is this okay if i hang it dead center of the tank?, or should i get two 3' fixtures and hang them side to side? i have my options narrowed down to either a

(1) 48 inch 8x54W Sunlight Supply Tek Light High Output Fluorescent Lighting Fixture
Sunlight Supply Tek Light High Output Fluorescent Lighting Fixtures)

or

(2) Odyssea 36" 156W (4x 39W) T5 HO Light Fixture Advance
Odyssea T5 High Output Lighting

im not limited to just these but this is what i saw and liked so i would like to hear some suggestions if you have any.
Thanks
Brian

 

I think the tek lights will serve you better than the metal halides. I have a 36" 6-bulb tek light over my 48" tank and I don't have a single dark spot. An 8-bulb 48" should light your 6' just fine.

 

ok thats what i was hoping for. thanks for the help

 

you could get qty (3) 60" 6x80w tek t5 retrokits and stagger the bulbs a little. that would work.. $600 with good bulbs..just have to mount them in a canopy..
