First time “modding”. Dedomed a 5k 519a. Easier than I expected. Followed Cheule’s q tip method.

Simple potting with some single component soft silicone compound to protect the components on the back side. tbh liquidity is not as good as expected, but at least it’s better than nothing and it’s easy to remove.
PS: Soft silicone offers limited impact resistance, but given that exposed electronics are vulnerable to metal debris or liquids, anything helps.

On the plastic ring for the switch
No DC-Fix, so I roughed up the surfaces with sandpaper for diffusion. It doesn’t make a real difference. Unsurprisingly, since 2mm thickness is not enough distance for the light to travel/diffuse from a switch LED to a point a quarter turn (on the order of 10mm) away.
This is really neat! Where did you source the potting compound, and how would you remove it? How does the potting compound perform thermally, since the 7135’s dissipate excess voltage as heat?
I’m thinking about doing this to some of my lights (possibly a Q8+, which occasionally burns up a FET or 7135 from what I’ve heard, if used with high-drain cells).
Refer my comments under this thread. Basically, almost any substance conducts heat better than air in a confined space, also that’s what these potting compounds are primarily used for.
It’s soft, can be dug out with tweezers or similar tools. I purchased this silicone potting compound for repairing my washing machine circuit boards, it’s generally easy to remove and re-pot.
Since the soft silicone itself absorbs some of the stress, I don’t think it’s too necessary to have very specialized equipment to remove all the air bubbles, but you can still try to remove some of them by heating them up with a hair dryer etc.
My advice is still that if there are no exposed components, there is no need for silicone potting.
Actually, I don’t even really like that these potting compounds conduct heat, the LED give off more heat and it may heat up the components on the driver through these compounds, this may have unintended effects or advance temperature control step-down on lights like the Q8+.

Probably because the rubber of switch is itself a diffuser
The rubber boot is the main and really only effective source of diffusion, and it works well because of its farther distance from the switch emitters.

Polished up my dinged up, originally red TS10. I stripped the anodization with caustic soda, sanded the scratches and polished up using a cloth polishing wheel and car paint polishing compound.
Raw aluminium is very soft so Im looking forward to anodize it again so it doesn’t scratch so easily.

Lumens cca?
I actually like the way raw aluminum looks and feels. I have several flashlights that I’ve filed down, sanded, and polished. Here’s an example in case you are interested: Cheapo Flashlight. And yes they can scratch easily, but can be polish again just as easily.
Please let us know how your anodizing goes.

I never cared for the spacing of the aux lights on the MTN triple. One of them wasn’t lined up properly with the other two. And it made the beam look wonky! So, I designed my own! And it’s glorious!!!

no spec on the emitter compared it here https://imgur.com/gallery/s2-vs-diy-mule-lkavKyf

Mule vs S2+ at 0,1%

1% but moved the S2+ to 100cm
TS10SG w 660nm:
Fun times! The TS10SG has a pretty good beam w SST20. 
other TS10SG mods in this album, sw45k, DD519a, XPP

Regarding sw45k and 519a
but more floody than I wanted
How it compares to regular TS10 ?
Also I’m surprised the dedomed 519a produced no artifacts. Did you use diffusion film?
TS10 is extremely floody, much more than any TS10SG mod. I do not use plastic films, they cut throw in half.
The goal of the TS10SG is to be throwy. LEDs w smaller LES (the phosphor size), make a tighter hotspot.
I think the LES of the SST-20 is a good match for the optic.
Smaller LES, such as XPP produce a tighter hotspot with more throw, but imo XPP has unacceptable artifacts in the spill, and I dislike the tint.
