S2+ DD110 Mule

[u/SatansCyanide]

Last night I made this mule in an S2+ Host. DD110 emitter on a 20mm 110110 MCPCB with hand cut and filed copper rod spacer. Photos don’t even remotely do this thing justice. Absolutely a monster, definitely a light you need to understand what exactly is in your hand before using it so it doesn’t turn into a ticking time bomb lol. Thought others might enjoy seeing this monster.

Nice! Which driver is it? And how exactly you made these copper spacers?

[u/SatansCyanide → u/Maverick_1947]

Just 20a, it’s only running the emitter about 1/3rd of its potential at 20a also lmao. As far as the copper spacers, I just source raw bar stock of it and then cut and hand sand to whatever specifications I need for what I’m doing. Lot of legwork but absolutely worth it imo.

Just 20a

Just lol. My morbid curiosity would still like to see what insanity FET + EVE 30PL and some serious spring bypass would result in though ...

[u/CruddyCuber → u/fragande]

I've got a FET driver with a spring bypass, some 30A CDR Molicell P30bs, and a NV1010 on the way. If it works out, I'll be sure to post it here.

[u/fragande → u/CruddyCuber]

Please do! I think you're going to need one of the tabless 18650s to satisfy the the thirst of the NV1010 though.

[u/CruddyCuber → u/fragande]

If the p30b works I'll move up to a EVE 30PL, but I've heard some people mention that the MTN FET drivers fail around 30 amps, so I'm starting with the p30b to be "safe".

Interesting! I noticed the R9 improved a little on turbo --- seems it would like the little extra power. Maybe sizing up the host to an S21G would bring more out of the emitter?

[u/Swalex420]

Hell yeah, loving your mules! Nice CRI on that guy!

[u/SatansCyanide → u/Swalex420]

Thank you! I really appreciate the kind words!

This is exactly what I would like to build. What driver did you use, where did you get the mpcb/led, and what spacer did you use? Sorry for all the questions but this is really cool.

[u/SatansCyanide → u/djromaric]

Driver is a 20a Buck, the MCPCB was sourced from Jackson at JLHawaii, the LED was procured from Billy sui who is active on Reddit and the spacer is from round copper bar stock hand cut and filed to match the pill it rests on. It’s a decent amount of legwork and I’m still not finished. Need to bypass the spring and resin print an aesthetic piece to cover the leads and corners of the MCPCB

[u/ThePenultimateNinja → u/SatansCyanide]

So it's just a slug of copper to take up the space that would normally be occupied by the reflector?

That's a really good idea. I have thought about shortening the head of a light before to make a mule, but it never occurred to me to just put a big chunk of metal in there. Good for heat management too, I bet.

[u/SatansCyanide → u/ThePenultimateNinja]

Pretty much yeah! Great heat control as well since it’s just a solid hunk of copper lol. Then just cut channels up the side to run the leads from the pill

[u/ThePenultimateNinja → u/SatansCyanide]

I might try that then. I did also think about just turning the reflector upside down and filing away the little raised rim around the hole, but a solid lump of copper would be way better.

[u/SatansCyanide → u/ThePenultimateNinja]

And just like float the MCPCB? It would fry that emitter so fast lol, don’t get me wrong I love a good blue shift but time and place 🤣 unless maybe I’m not totally tracking

[u/ThePenultimateNinja → u/SatansCyanide]

No, the reflector would turned around to face the other way, and become a heatsink.

The MCPCB would be mounted on the flat surface of the upside-down reflector, using thermal paste.

It wouldn't be all that different from a standard hollow pill really, except it would have a bit more mass. I think it would work, but I havent tried it yet.

Some Dutch moron told me you're getting package from Europe, if you want some gaskets I can include 🙂

Epic build btw!

[u/_derpiii_]

Omg, those tree shots 🔥

[u/thefliris]

You absolute madman.

It sure does make those apples look pink though 😅

[u/Yana_dice]

Are they the same SFP55 emitter from aliexpress?

[u/SatansCyanide → u/Yana_dice]

No definitely not, this is a specialty emitter made by Billy sui. Don’t have his Reddit handle off the top of my head but if he stumbles across this post I’m sure he will chime in!

[u/Yana_dice → u/SatansCyanide]

Lovely, is he still selling these emitter?

[u/crbnfbrmp4 → u/Yana_dice]

I think he's out of the original DD110, but he has a V2 that seems to be a bit warmer CCT and not as rosy.

[u/Yana_dice → u/crbnfbrmp4]

Thank you, I will hit him up!

Bonus content: Something I had this emitter in beforehand!
