    Hi,

    So I've just completed my new LED light for my nano reef tank (well the tank itself is still cycling).

    Anyway, for anyone interested in the build here's how it was made and the parts you'll need.

    Items:
    2 x 3W Cree Blue LEDs
    2 x 3W Cree Royal Blue LEDs
    2 x 3W Cree Ultra Violet LEDs
    6 x 3W Cree Cool White (6500K) LEDs
    12 x 60 Degree Optic lenses
    2 x BuckPuck 1000mA Drivers (dimmable with potentiometers) (DC drivers)
    2 x 24V 1A+ AC/DC Power supplies (I got 1x 24v 1.5A and 1x 24V 4A) (AC to DC adapters)
    1 x Aluminium Heatsink (mine is 10cm x 40cm x 1.5cm)
    2 x Thermal past tubes
    1 x Aluminium Trunk bar (from Builders warehouse) used to make bracket
    1 x Roll of Wire
    1 x Electronics enclosure box
    1 x Tin of black gloss spray paint
    24 x 3mm screws (self tapping)
    2 x wall screws for the bracket

    Tools:
    Soldering iron
    Hacksaw
    Stanley knife
    Drill
    etc

    1. The items arrived:

    2. Map out the placement of the LEDs

    [​IMG]

    I went with the follows:
    W RB W V W B
    B W V W RB W

    3. Drill the holes for the screws that will mount the LEDs (use a 2.5mm drill bit as the screws are 3mm self tapping)

    [​IMG]

    4. Put a small amount of thermal paste on the back of the LEDs and screw them in place (not too tight, just enough that you can just see the thermal paste squeeze out the sides every so slightly).

    [​IMG]

    5. Solder the LEDs (Positive to negative, Positive to negative, right through). I am connecting all the B, RB and UV on one dimmable driver and all the W on the other. This way I can dim individually to find the perfect colour/look. Below you'll see white wire = white LEDs and blue wire = B/RB/UV LEDs.

    6. Then connect the drivers (one driver per power supply) to the LEDs (I started with both dimmed to zero and then turned them up slowly, just in case. All was fine though.

    [​IMG]
    You'll notice the UV LEDs in the centre seem less bright, they aren't - its just the UV colour spectrum is almost out of our visual range so it just appears that way... to the corals however its perfect.

    7. I then attached the optics (which needed a small..tiny.. dab of super glue to ensure they stay in place and don't end up falling into the tank later.

    [​IMG]

    8. Then solder the wires together and cover with insulation tape and place into the enclosure with holes drilled etc for wires in/out and the potentiometer.

    9. I then covered the full bottom part of the heatsink in masking tape, to ensure no paint got on that surface or the LEDs etc, and sprayed the heatsink black.

    After this I built a bracket (not going to go into details of that build, its self explanatory). I used pop rivets to hold it all together and mounted it to the wall at my desired height. Please excuse the polly filler on the wall, this was from my old LED flood light that I took down to replace with this build.

    White 70% + Blue 70% (I like this combo and will probably stick to it as my default)

    Anyway, I hope this helps anyone looking to do a similar build. Feel free to ask questions.
