What did you mod today?

For a very long time I’ve been looking to do a mod, inspired by this thread of g_damian, and this CRX thread, and this Firelight2 thread, and even some comfychair mods I once managed to see.
To all of you, thanks for the tips and and descriptions of the work done, as it was a tremendous help :beer: :face_with_monocle:

What I wanted to do was a “shortened” Convoy S2+, triple, using a Jaxman 18500 battery, and using an 18650 battery!
This week I received the tube and yesterday I took some time yo make it happen :smiley:

I had to “dismantle” the blue S2+ that I put together sometime ago here and I used an extra S2 pill I had for the job! Used a file, and my Parkside tool (dremmel like) with a cilinder of sandpaper and a drill for the middle hole.

The leds are Luxeon V2 3000K :heart_eyes: , under a Carclo 10511, and powered by a TA Bistro HD OTSM driver from Lexel . The retaining ring was made by kiriba-ru, the FC switch is from Convoy. The pocket clip is from Nitefox ES10K, and the blue tailcap from the LHT store at AliExpress. The GITD gasket is from CRX :wink:

I put some adhesive tape to mark the limit I wanted to file/sand, and also to protect the other threads, as sometimes it hard not to damage something.
Then I did the filing/sanding work until the top of the pill was flat and until I had taken enough material from the threads so that the pill could get it but still make “contact” with the walls of the head. Then I drilled the hole in the pill.
And the the rest was soldering and putting things in place.

The 18500 tube colour matches pretty well with the S2+ colours, and only the knurling is slightly different.

Vs XP-G2 S4 3C (5500K) >>>>>>> Vs Luxeon V 4000K >>>>>> Vs the glow gasket of my Convoy S6 :smiley:

Convoy S6 > Convoy S2+ Desert Tan > Convoy S2+ black > Convoy S2+ blue > Convoy S2 18350 > Convoy S2+ DT 18350 > Convoy S2+ black 18350 > Convoy T2

Nice work! I like the proportions of it, always thought the std is too long, and 18350 too short. :beer:

Nice mod and pics, MascaratumB! :+1:

Thanks :beer:
Yup, the size of it is quite nice this way. To be even better, it could be slimmer to take 16650 cells (which have a reasonable capacity, even if not
so good for high-drain). THAT would be cool :wink:

Thanks g_damian :beer: Your work inspired me much in this mod, so thanks for your details too :wink:
This will be a “user” for sure, as it has a great tint, a UI that I like an can configure, and also takes a good capacity/high-drain cell :wink:


Great mod. I especially like the pocket clip; one major obstacle for me to carrying my S2+/Jaxman E2l these days is the horrid clips I’ve got for them.

They also lose out on size to much better lights, but that’s another story.

I modded a MT35 Plus with SBT90.2 a few weeks ago. Here is the thread if you want to look. MT35 Plus with SBT90.2 mod ( GT90 kit from Texas Ace )
22 amps on turbo
5800 lumens
2700 meter throw



I like your mod MascaratumB. Nice job!

Thanks Scallywag :beer:
Yup, that pocket clip is quite nice, smaller and thougher than the “screw in” clips that Simon and other stores sell. AliExpress sells some nice clip, you may wanna take a look there. They are bigger than this one, though.
I forgot to mentuon that the clip was previously used in th Jaxman E3, and by that time I “flamed” it with a lighter, hence that blueish colour.

Thank you Neutral Fan :beer:
Turned out quite nice, I guess, doesn’t it ? :wink:
Not a very difficult mod, but with a nice result!!

I reflowed Nichia E17As onto a VR16SP4m board! Mic drop…

Never again will I attempt to do this. The board is a little beat up due to breaking the original E17As that were perfect from Virence, trying to reflow other E17As that went horribly bad, and then super gluing an LED spacer as an experiment.

I put very, very little soldering paste onto each of the 4 LED pads, but it was still too much. So I removed the extra solder with a toothpick while positioning each LED into place, but then 2 little solder blobs got between the LEDs. Argh! Once the board cooled down, luckily I was able to split a toothpick and pluck them away.

About super-gluing led spacers. I use a different approach.

- first I superglue a 2-3mm long part of a plastic tube around the led.
On the search for a suitable tube the outer diameter is paramount.
The outer diameter shoud fit (not tight but snug) in the hole of the reflector.
Any attempt to bring the diameter down is (in my case) a risk of it not staying circular…
The inner diameter of the tube is less critical for me as I have plenty objects to enlarge it.
I try to make the inner diameter as large as the diagonal of the die.
That should be enough to CENTER the led properly.

Then I will look for a piece of plastic to make a “shim” that I can place on the leadboard.
With the above mentioned tube poking trough. The reflector rests on the shim.
Find the correct thickness for the shim and you are able to FOCUS the led.
As a bonus, such a shim prevents the leads to short with the base of the reflector.

Unless you find the ideal centering ring it is always a bit of a wiggle to CENTER and FOCUS.
My method divides that time consuming chore into 2 separate (quite easy) actions.

Been wanting to build something like this for ages, although made a slight mistake as the driver I wanted to use were 20-22mm. So I had to find an alternative 17mm to use. Lower amps, but hoping it’ll still be quite nice. Unless anyone knows of a similar sized host that uses larger drivers?

Convoy M1. I have an original when Simon first launched these, the current version is nicer. Shorter overall, more matt anodising and different machining.

Matched with a 17mm driver and a 5000k Cree MT-G2. A big LED in a relatively little torch :smiley:

Wires soldered up:

Tidied up and driver seated and retained:

The reflector gets quite close, so to avoid any shorts some insulation of the contacts:

The reflector needed no mods, the hole was big enough for the MT-G2. Centring was a little challenging as I’m not using any kind of gasket or ring. A few tweaks to the star and screw down tight and probably a fair does of luck and it doesn’t look too bad :slight_smile:

The LED dome fits well in the OP reflector.

Final touch a deep carry pocket clip:

And we’re done!

Will have to wait until it gets dark to try it out and I’ll see if I can get come cd/lumen readings. I’m not expecting it to be a lumen monster due to the driver choice. But the beam is looking quite nice so far. I wanted something with a nice bright even beam, but with more throw than a flood TIR or aspheric lens.

Cool, will be looking for those beamshots :wink:

I’d be interested in seeing some pics if you have them.

I found super gluing the regular LED spacers, with the ends cut off, works very well.

I envy your soldering skills NeutralFan! Looking good :wink:

The Boruit BC07 is an interesting flashlight. The quality of workmanship surprised me. Although I do not like zoom flashlights, I will probably leave this one for myself.

Boruit BC07

Difficult to get decent beamshots to really show the difference.

Thought I’m compare to an XM-L2 Convoy M1:

The beam is a lot more even on the MT-G2, which was my aim. Make it more useful at closer ranges and less intense hotspot when out walking.





It still has more throw than your average tube light too. Although clearly this is a long way from a thrower.

On my setup at home I’m getting PEAK readings of

Convoy M1 MTG2 = 1209 lumens and 6358cd

For reference:

Convoy M1 XM-L2 = 745 lumens and 11,988cd
BLF A6 XP-L = 876 lumens and 5416cd
Lumintop FW21 Pro 3 x XHP50.2 High mode = 1380 lumens and 2951cd

Nice mod Chicken Drumstick. And interesting how much the M1 has evolved. I have the M1 host in my Convoy Store cart along with a bunch of other goodies.

Interesting, thank for showing this. :slight_smile:

Sorry I can’t help you right now. At “le moment suprème” the battery of my camera was empty.
In the meantime I would like you to refer to this POST where I tried to explain the build of my Fandyvoy (Fandyfire STL-V6 + Convoy C8). After charging I will try to re-take the left picture of the pill a bit better.

That post helps a lot. No need to take further pics.

Since I frost the lenses of my E17A flashlights to remove the donut holes, I don’t need to worry about focus. Does your technique work on E17As?
