Ok I have a few mods I did over the last few weeks
to share, thanks to @MasterNate for designing and selling me the MCPCBs.
First, a funky TiTS10 Mule:
I modified the MCPCB slightly to accomodate 2 0603 aux LEDs (glued on with UV resin and then connected up using 30AWG teflon wires). To connect the CSPs I carefully scraped away the soldermask over the respective traces and soldered directly with 28AWG silicone wire - the traces are thin enough that there’s not much point using thicker wire even at 100% FET. The driver used is a standard TS10 driver.
The spacer is made of some 15mm square copper shims soldered together with the help of a hotplate. Total height of them was 3mm but I think 2mm would be a better choice for a lens.
Tintmix of 5700K and 3000K Samsung LH181Bs (I’m an idiot and accidentally ordered 70CRI 5700K ones because Digikey didn’t list the correct values). Opple says around 4200K and 85CRI which is acceptable since it also has a very rosy tint.
I currently have a really crude lens made of UV resin as I didn’t measure the height of the spacer correctly and the bezel is almost flush with the top of the PCB. Once some 17mm lenses arrive I’ll probably sand down the spacer to fit it. (Took this image with a test run of an older group of LH181Bs and the stock 6000K emitters before reflowing the new ones on)
The aux LEDs actually look really pretty but they kinda make an angry eyes face with on high.
Now some with more traditional high power LEDs:
One contains 3 519a 5700K DD measuring around 4000K through the optics. Red aux
The other has 3 W1 with the RGB aux board on top.
0402 LEDs aren’t the easiest to hand solder and I discovered that the hard way after spending nearly an hour on this xd
Here’s them side by side on a low ramp level.
Now with the TIR, I locked the white balance to the 519a so the W1 ended up way greener than it is IRL
The RGB aux looks really cool but the colours don’t mix as well as I’d like. I might dollop some UV resin over the LEDs and sand it to diffuse them a bit more, and the green channel could do with a bit more series resistance.
The W1 is definitely throwier and gets just as hot as the 519a. Both still out-candela the stock emitters.
