I am putting together a plan to convert my tank over to LEDs. My tank is a 150 Tall. 72 x 18 x 27. I run a SPS dominate tank. I currently have 1000 Watts of halide as well as 250ish Watts of supplemental T-5 and VHO. As you can guess, bulb replacement and heat are issues. I have been going over several threads about recommendations and decided you would be be asked directly. I am guessing that 2 x 48 Ultra Premium LED DIY Kit with Dimmable Drivers spread across 4 x Drilled and Tapped 4.25" x 16" Heat Sink for 24 LEDs. 48 Royal Blue 36 Cool White 12 Neutral White 60 degree lenses These would be spread out across 8 drivers and be setup to provide a dusk / dawn from one side of the tank to the other, providing a "eastern morning light" look. What do you think? Will this be enough light? Will it be able to cover the entire tank footprint while still growing SPS on the sandbed? Edit: Also cooling. I would still want these mounted within my canopy. How can I cool these if they are mounted to the top of my canopy? Do I need to leave a space in between?
