Anyone have any suggestions on how to light a 60''x30''x25'' aquarium? T5s only would be as simple as an 8 bulb ATI fixture, but I'm really looking to incorporate a LED/T5 combo. Would the Aquatic life hybrid fixture cover the 30'' depth for a SPS dominate tank? If so, 2x or 3x reefi duo extremes? I may choose to go with a 54''x30'' tank instead. Still undecided.
Starting w/ sort of a power baseline ..600-800W of output.
T5, MH, LEDS have similar efficiencies of output. Delivery is another story.
If considering hybrids you have really 2 choices 48" or oddly 61"
Ends of t5's have bad light falloff so best to get close to the correct size.
Now hybrids are about 18" wide and your tank is 30"
Choice is to live w. some falloff f/back or raise the light a bit. Losing par by increased height.

So 4 x 80 = 320W
Suggest for spacing unos not duos..
www.reefi-lab.com
180W max power, 83.3% of the power level of ReeFi® Duo Extreme.
3 = 540W
Total available wattage is 840 but if used "normally" unlikely you will run the Unos at 100%.
Good thing is you can always add an Uno if you need to.
For the 60 and 61" hybrid when raised you will spill light left/right but should be minimal.
If you go 54" and use 48" hybrid, somewhat the opposite, less end lighting but placement of the 3 Unos can adjust that somewhat..
$350 X 3 =1050
$450 for the T5 hybrid
$100 for bulbs
$1600...
Now the bad news sort of.. Reefi reflectors look to be about 80 degrees...
So a sort of mis-match between the t5's, tank and them.
Optimal height is about 18" off the water line for a 30" wide tank.
Optimal height for the hybrid is around 8"..but depends on your width.
soo guess would be to go 16" end plates, 3 unos and 12-14" high.
Somewhat counter intuitive from the vid above but it assumes more "work" is done by the LEDs..
consider this just a "food for thought"..
For $890 you could just throw 2 400W MH's over it..
