So what's the watt per gallon rule of thumb with LEDs? Any recommendations for a 48" long 75 g tank?

For LPS you can use 1.5-2W of LED with 60 degree lens to each gallon of water
For SPS you can use 3W of LEd with 60 degree lens to each gallon of water

first pictures of the new light....

Here's the very first full tank shot with lights on. Now the t5's arent on yet as I still hadnt received my bulbs (not included). I ordered 2 of the new KZ 2nd generation and 2 of the KZ Fiji bulbs. The leds are all set at 100% in this picture and the light is resting on a couple of 1x2's on top of the tank. I grabbed the par meter real quick to see what kind of values I would see and I took 2 readings at the midline of the tank. The first was on the surface of the water about 3" below the lamp and that reading was 1600. I lowered the sensor about 18" below the water and i was getting a reading around 350. I know blues dont measure correctly on a par meter and they can be off by as much as 30%. My bulbs arrive today and once I get the lamp hung and the bulbs in I will do more par tests.
