LEDs are done! everything went together perfect, bright as hell. went with 8x 3w Cree royal blue, and 4x 3w Cree neutral whites.
Im not too happy with the finished product though...the problem is the tank is now a 70s disco club! all over the rocks and sand is white and blue flashes! its hard to look at up close. I actually spaced the LEDs closer that the recommended 2" and still get color shadows galore. Think height of the array above the water has something to do with it, but i cant go any higher...
Both colors are dimmable, and ive got it settled at around a 20k bulb look. noticed my heat sink gets pretty warm, so i might have to add a fan. The 8 blues are pretty overpowering. Ive got my whites up to maybe 25% and the blues to maybe 15% and its still pretty purple. thinking of adding a string of cool white right down the center...
ebay heat sink. wanted the mounting holes at the top. 9.5" x 5.5"x 1.25". sand blasted and drilled and tapped 24 holes (didnt even break a tap!)
LEDs mounted. Liked the heatsink cuz its got a groove, which ill slide a glass plate into to protect everything.
mounted at the top of the bookshelf. camera makes em look super purple for some reason. Its not that purple in person.
excuse the temporary wiring mess
Ill finalize the install in the next few days and clean everything up and see how i like it.
