Soundwave,

Thank you for taking the time to write up such a detailed thread.

I have a few questions, that I could not find an answer too reading all the other pages.

1. You attached 24 Leds to each heat sink that was 12"x8.5", can you tell me the spacing / distance between each LED and Row

2. I believe you used Cree XRE Q4 LEDs, I am looking at using the CREE XRE P4s, any opinions or downside to this change?

3. Also could not find the dimentions of your Tank. HxLxW? Sorry I know you have mentioned a Stanard 75Gallon, but I am in Australia and may mean something different.

4. Your fixture is 48" by 8.5"?? Do you have the measurements for the placement of the lights/heatsinks within the overall fixture?
E.g. The heatsink is x" from the end of the fixture with x" between them.

Thanks for you time in replying.
