Custom DIY reef light

Here's a project that I've been working on for the past couple of months that some of you might find interesting. I took inspiration from the 1st gen ATI straton as they are the best looking light on the market. I dont have a background in electrical engineering or really building anything electrical so it was fun learning how to design a custom pcb and solder everything together. I do plan on building a couple more for my 200gal tank im setting up, so any pointers would help. I have not tested any PAR values but they should be the same as the straton because the LEDs are being ran at the same current. If anyone has questions, ask away.

Nice job!

I'm not familiar with the ATI light, but were you able to use the same diodes as the ATI fixture?

From the research I did ATI uses diodes from multiple different manufactures. I didn't use the exact same diodes but the nanometer ranges are almost identical. They are 3535 cree xp leds with the same pattern and amount of colors that ATI uses.

Looks really good . Will you be posted a build thread in these
