I have not, but glad it works for you…
agree about DD 519a, and I think an XPP is also a great option.
Here is the beam of XPP in a TS10 Triple, (mod thanks to MasterNate):
All three lights are set to 200 lumens.
Also agree Heat really helps soften the loctite… that would have been my next move if the bezel had not come loose without heat.
I have not bought a fine tip for my iron, but I might at some point.
I look forward to your success modding your TS10SG, and will be very interested in seeing your results
Im tempted to try to replace the SFT25 without disassemby, by using hot air… but Im undecided. Meanwhile, I will shop for a fine tip for my TS80
Im not a fan of Low CRI LEDs, so Im not planning to use the TS10SG as is.
I took a photo of my leg, injured by my cat when he slipped while jumping out of my lap, to show the difference between the SFT25 and some sw45k in my TS10 triple (mod thanks to MasterNate)
Low CRI throw, vs High CRI flood, at very close range:
To be fair to Wurkkos, the TS10SG is not intended for close range illumination, and it is perfectly suitable for its intended purpose as an outdoor thrower. In fact, Low CRI just makes green leaves greener and arguably prettier…
