The 14 XP-E (Royal blue) and 14 XP-G (Cool white) Cree LEDs finally arrived on Friday, and I wasted no time to finish the 28 LED build for my frag tank. Basically the same concept as the 8LED build. But for this one I used the dimmable Meanwell drivers.
The fixture itself is 29″ x 4″, made some awesome Aluminum channels from Home Depot. I bought 2 sets, chopped them up to size, riveted them together side by side, and then put the other halves perpendicular. This gives the fixture plenty of surface area for heat dissipation.
(please reference https://reefblog604.wordpress.com/2011/03/18/8led-build/ for wiring/soldiering details, it’s essentially the same concept):
