180w DIY pendant.


Before this light I had never soldered, never really played with this side of the electronics, so far it's been really fun.
At first I tried to drill my heatsink, broke my bits, forgot it needed to be lubricated.... I bought a new heatsink and went with arctic alumina, I actually just finished glueing them on a few minutes ago, and although it could have been better I plan on adding some leds to it later for more fine tuned color.

Specs
18x Cree XML 6xww 12xcw(more to be added down the road)
DIY drivers made by o2surplus
DIY controller also made buy 02surplus
Black anodized aluminum heatsink by rapidled.com 6"x10"
Optics aren't decided yet I may go 80 degree
Power supply is a meanwell 24v 6.5a supply

Not the cleanest job but it will work how I want it to. I put the optic on there to see if the shield would fit with them on there.

Also this is going on a 50g, before freaking out on me I won't be running this at Max that would just boil my fish.
It will for sure have active cooling. I have a serious computer fan going on it that will be on a controller. I still have to solder some Connections, running
It through 9pin dsubs for a cleaner
Look

Got a lot of the wiring done, all the less are soldered the dsub connections are complete as well. I still need to pick up a couple drivers and
My controller then I'll be able to test it

Mounted the drivers and the power supply on some plexiglas along with a terminal, got everything all wired the pendant is hanging an I even tested the LEDs, I still have to wire the controller to the LEDs and then mount the controller before it is totally complete but I'm almost there.
I must say this light is BRIGHT I have the strings at about 80% on the manual dimmers I'll probably cut it in half depending on par readings, I have no optics on it right now so I'll adjust it to 100 par at the substrate at max and go from there.
Time for bed. Photos tomorrow
