What did you mod today?

Thank you for the great photos.
Very Creative work, and excellent English :wink:
Welcome and congratulations!

1 Thank

Modded TS10 Max with a MTN quad mcpcb and Carclo 10622 optic. It was an old mcpcb I had laying around so not sure what CCT the 519A are. Beam doesn’t look terrible, even with the amount of optic covered by the bezel. The hotspot looks nice while the spill is quite jagged looking, much like my S21A quads.

Not sure if I’ll keep it like this or go back to the stock triple setup after reflowing some different emitters.

How’s the beam?

honestly from what i understand it looks a lot like my s2+ with the same leds and Carclo 10507

Very simple one today- TIR swap (3°) and blue glow in the dark tape (from AliExpress) into my newish M21H.

5 Thanks

What emitter do you have there and how’s the beam? Post some beamshots, pretty please. :slight_smile:

XHP70.3 HI but folishly went with the R9050 rather than the R70.

Took apart my bike light and reflowed some Yingding 6500k onto it, paired with a dual 15⁰ and dual 10x45 striped TIR lenses from Simon. This upgrade made a HUGE difference in the performance of this cheap amazon light

Definitely some nice intensity boost there. Is the egg yolk variant high CRI? I have a glass version and it’s truly a unicorn, 7000K of super rosy high CRI :unicorn:

I couldn’t get a reading with my Opple, i did reflow the 3000k emitter into my SC31 Pro and it measured a bit below 90 CRI and 3000k.

I took some comparison photos, i have two of the same bike light. The difference is crazy

Congratulations, and thanks for the details on your mod.

Do you know if the parts you used would work as a direct swap on a TS10SG?

iow, would a Black Convoy T3 bezel and the SP40A TIR (do you have a link?), be a direct swap?

1 Thank

Yes, they would work on the TS10SG, but the finish will not match, as the TS10SG is more matte than the T2 black bezel. If Wurkkos decides to launch the SG in red with the standard glossy anodization instead of the new matte anodization it will be a 100% match. Orange will be very close too. Threading is a 100% match, and the outside diameter is also exactly the same (SP10 bezel is slightly skinnier).

The SP40A TIR will need some sanding to reduce the diameter, and you will need to make a custom centering solution for it.

Edit: the listing is closed, but there’s the link in case they have more units. ----LINK----

thank you very much for the details about the bezel fitment and colors
and for the link to the Tir you used, the dimensions are very helpful

unfortunately these 20mm Tir are too tall

anyway, I decided to swap out the TS10SG SFT25 in favor of SW45k. And it all worked!.. pending nighttime testing.

1 Thank

Nice mod! I noticed that in your beamshot, the hotspot is quite a bit yellower-greener than the spill. This might explain why the SFT25R measured such high duv in this light: the optic fails to blend emission from different angles and accentuates green tint in the hotspot.

3 Thanks

There IS a huge difference in Tint before and after:

4 Thanks

It also seems that the radial shadows in the beam are not as prominent. Larger hotspot. So what are you losing in throw and lumens?

1 Thank

the sw45k makes 50% of the maximum Turbo lumens of the SFT25… but since I seldom use more than 200 lumens around the house, that makes no difference to me. And I gain in High CRI and No Green Tint…

also note that in Tactical Mode, the stock TS10SG made 335 lumens on my meter, while now w the sw45k, it makes 275 lumens… iow just 20% less…

Honestly, the lumens change to gain High CRI is totally worth it, to me.

later tonight I will test whether the sw45k illuminates the bench at 50’, which the SFT25 did easily… per this photo:


atm it is still daylight here… give me about 3 hours and we shall see, together :wink:

5 Thanks

The TS10SG w sw45k is on the right:

not as big a difference as the SFT25… but the sw45k mod suits me better… I would not use the SFT25, Im too committed to High CRI, so for me, the sw45k is a keeper.

One of the things I like about this mod, is that it demonstrates the impact of the LED, separate from the impact of the optic.

If I could find a 3535 LED with a tiny LES the size of the SFT25, but with High CRI and negative DUV, I would use it… I just dont know of one atm…

I hope someone does a DD 519a test in a TS10SG… that might be a bit punchier than the sw45k

Another takeaway from this TS10SG mod, is that Domed 219B fits under the Tir… thats a big win for me, since Im very fond of domed 219b, and in some lights it produces a better beam than DD519a… Although, DD519a will probably work fine w the TS10SG Tir…

Another win for the TS10SG modability to 3535 High CRI, is I dont have to swap mcpcb, and I dont need to move those tiny RGB Aux
