Fancy LEDs.

I'm getting tired of some of the cheap chinese low light quality leds I have hanging around my house, and I've got a bunch of fancy 2700K 90+CRI leds laying around somewhere, but I did not yet have a PCB to put them on.

I wanted to stay below the 50x50mm limit for the cheapest option at the boardhouse, and managed to get 30 of the 5630 LEDs on it. At about 30 lumen per LED this should compare to a 75 watt incadicent bulb, which is pretty neat for the 9W the LEDs will consume. Each LED has it's own small top and bottom copper plane for thermal reasons. Pictures:

I got my PCBs and stencil! I just have to wait for the resistors, and then it's time to bake. 

Another edit:
All done!
