Full spectrum reef light for use with BLC06

[Space-Stick]

Hello,
I have been thinking about trying to make my own reef light for a couple months now, but I was daunted by app development and programming the light schedule code. This project looks very clean however. Currently my idea is to 3d print an enclosure using ASA and use microscope slide glass in front of the LEDS. The lid would have the fans and floss filter to hopefully reduce intake of salt spray.

The LED board is an aluminum single layer PCB, which should be very affordable. I am using high performance SMD LEDs. The spectrum is very broad, but mostly UVA and Blue, with high temperature white and moonlight white, which should be good for a reef tank. I think I will recreate BLD06 with the functionality of the BLB0657F and a BLC06 mounting point, as well as mounting holes. Then connect the LED board with wire. Even though I would be ordering 3 different boards, I think this project would still come out under 280 dollars, although I have not confirmed that. While that is considerable, the alternative is 400 dollars for reef tank LEDs that might be potted in resin and thus un-fixable if they break. I apologize if my current board and 3d model is crude, this is my second pcb design project, my first time using freecad, and I just started Saturday so I have a lot more to do.

Wow, your project is impressive.

However, I noticed some issues with your board at a glance:

1. The power traces are too thin. Make them as thick as possible, or you need to calculate and add some margin.
2. Don't consider soldering wires to an aluminum PCB. Instead, you should use SMD screw terminal blocks or pin-headers or nuts. Aluminum PCBs cannot be soldered with a soldering iron.
3. For the enclosure, you can use an ABS plastic case and cut holes instead of 3D printing. This will significantly reduce costs. I personally never use 3D printing, I think they break easily and look ugly. You can search for "waterproof plastic enclosure" on Amazon and find one that's large enough.
4. Your aluminum PCB doesn't seem to have the mounting holes for a heatsink on the back. I don't know the power of your design, but for high-power 3W or 5W 3535 LED chips array, you'll typical need a heatsink and a fan. I suggest finding a suitable heatsink first and then designing the PCB, since the PCB shape is something you can control easily.
5. Please add a SMD NTC to your board so the design doesn’t go to waste, yes please.

Have fun!
