    Yep the light puts out quite a bit for its size and is really efficient. I like the driver because I can lock to single mode if I want. My 19 month old daughter plays with this light after itís locked in moon light. She runs around in the dark, pretty funny. Gotta start em early

    defo, flashlights have to be one of the most useful tools ever, no matter what the age.

    Funny you should say about single mode, thats what i have on mine, the 2nd group is more a traditional low/med/ high . But the single "do it all" level gets used mainly, click once and every time i know what i am getting, no clicking through modes to find the right one. Just one level of usefulness..................just works.

    Wow, just about read my mind as i was thinking about something like this for my 7 yr old. Can't kill it, can't blind himself (with the right settings), then when he shows some brains i can show him what it really does. Imagine the realization when you grab it after he's played with it forever, swap modes and hand it back to him screaming in the darkness lol!!!

    On a more serious note, this is great!!! I want to start potting some electronics but i need to solidify my ideas first so i don't make a permanent mistake lol. This driver is what ven recommended to me and it suits tons of different needs, i like that you can make all your lights the same but different as well lol. I love it! Great choice and thanks for sharing!

    I ordered my magnets from simon at aliexpress but they haven't come in yet. Is this the same one?

    Yes the magnets are the same. Little hint I didnít glue mine in. I used a piece of printer paper on one side as a shim and pressed it on a hard surface. This way if I needed to replace the magnet I can. It has not moved or loosened one bit and has been my edc for 6 months with the magnet. I have the 18650 and 18350 tubes and both work with this magnet, itís pretty strong. It comes in handy so often.

    Good, i was hoping the magnet was stout!!! Good idea on shimming it in tight instead of gluing!! It's a feature heavily missed when i use a light without one!!

    Lol, aint that the truth!! Or a wristband compass!

    Would be cool to have an electromagnet on a light. The magnet would only be activated when the light is on. Be tapeworm on runtime though lol!

    I've had a few magnet fitted lights be saved from falls though by snagging something on the way down. But they were smaller!

    Are there any good qaulity GITD o-rings available that are a wee bit thicker than the ones that come with S2+'s?

    What type of contact is that on your tailcap spring?

    Sorry for the really delayed reply. The contact is copper to provide a better contact with spring and the bypass. Better than using a blob of solder.

    Here's a mod I did to a Convoy S2+. The host is one of the blue Convoys with the beautiful metal clicky switch. I've had this laying around for awhile, but finally decided to do something with it.

    I performed the following mods to this light:

    • Installed DrJones H17F driver and triple XPL HI 5A2 on copper Noctigon
    • Carclo 10507 Optic
    • Significantly reduced overall length of the light.


    NOTE: the bit of bare aluminum at the top of the tailcap where it meets the body tube is not present in the final version. Initially, I thought to shorten the light by reducing the tailcap length. I started to do this by filing down the bottom of the tailcap. Later I decided that didn't look good and wasn't necessary. I ended up replacing the tailcap with an identical one, but without any filing on it.



    Overview and pictures:

    Step 1: Shorten the pill. I used the same technique I used in a previous mod. Here are some pictures (taken from an earlier S2+ mod using the same technique):



    Shortening the pill requires the following steps
    :

    • Grind off the back of the pill. I used a grinding bit and a hand drill, then filed it flat. If you're patient you can accomplish this step using just a handfile.
    • Use a handfile to remove the forward section of threads near where the emitter sits. The S2+'s head isn't fully threaded so this is necessary to allow the pill to seat further forward. You can see on the picture above how the sides of the pill below the emitters are smooth. This is because I ground off the threads.
    • Grind out new ledge for the driver in the sides of the back pill. To do this I placed the pill upside down in a vise. Then I bent a small piece of aluminum into a "U" shape with a flat bottom. and placed it upside down in side the pill. I cut away the legs of the "U" till it sat just a few mm inside the pill. Then I used a cylindrical grinding bit in a hand drill with no grinding edge on the bottom to grind the edge of the pill. The "U" acted as a stand to prevent the grinding bit from slipping further in.


    Step 2: Install the driver and emitters. I chose a DrJones H17F for this build and triple XPL-HI 5A2 on copper Noctigon. Due to the nice brass pill, it was possible to solder the driver in for an excellent ground connection.

    Step 3: Shorten the head. With a dramatically shorter pill, the light was usable as-is with the 18350 tube, but with an 18500 inside. However, I've already done that before and wanted to make this an 18650 light. With the much reduced pill, the battery compartment is much too large for an 18650 cell. I considered sawing the battery tube in half and using the "human lathe" method to shorten the battery tube. But then I realized there was a much easier way to shorten this light:


    • I took a hacksaw and sawed a large chunk of the back of the head off. Since the pill threads and the battery tube threads are the same, this worked well. I then filed it flat.
    • The threads on the battery tube were hitting the back of the pill so I used a handfile to remove approximate 2 mm of threads. There's still more than enough threads left for a strong fit.
    • I used the same technique described in Step 1 for grinding out a driver ledge in the back of the driver to grind out the bottom couple mm of threads in the head. This allows the head to fully seat and still be o-ring sealed. this operation was the hardest part of the mod. I messed up the first time and had to take a little more off than I anticipated when the grinding bit slipped. Fortunately, for anyone else trying it, this step is also purely optional. It's only needed if you want a waterproof light and don't want to glue the head to the body tube.


    NOTE: the stand that I made to hold the grinding bit at the right height for this operation was a bit more complex than the "U" described previously. For this operation I cut 2 disks of sheet copper sized to the inside of the light. Then made a rectangle from a strip of copper and placed it upright between the 2 copper disks. I soldered all 3 pieces of copper together to make a secure stand that would sit inside the head while I used the drill bit. I did the grinding with the pill removed._

    The result: a much more pocket-friendly 1x18650 Convoy. Entire light is now just 102mm long, compared to 118mm for the stock light. A full 16mm was removed. It is now definitely one of the shortest 1x18650 tube lights with a clicky tailcap switch! Here are some more pictures:


    I am quite pleased with the performance of this light and really like how it came out. I limited the turbo output to 3 amps as I found that on FET modes the head got far too hot given the tiny head and lack of heatsink fins. Since the heatsinking isn't good enough to hotrod for max output, I'll probably skip adding a wire bypass to the tailcap spring.

    Overall, this mod wasn't really all that hard to do. I give it an intermediate level of difficulty. Well worth a try for anyone with basic modding experience who wants an extremely short tailcap clicky tube light.

    The new short head also works with the 18350 tube with an 18350 cell inside.

    However, note the gap between the head and the tube. This is because I didnít file off the threads on the 18350 tube as much as I did on the threads on the 18650 tube. This gap wouldnít have been there if I hadnít accidentally slipped with the grinding bit and ended up having to shorten the head a little more than I first intended. Also, in retrospect I donít think I should have tried to shorten the tailcap at all. If I were doing this mod again Iíd fix those problems so there were no visible gaps.
    As-is, I might be able to fix the gaps on the current sample, but to do so Iíd need to open up a little more room inside the battery tube. I should be able to get 2mm from filing down the top of the switch retaining ring and contact post on the bottom of the driver. But to get more than that Iíd have to grind the pill flatter.


    Here are some pics of the light with 18350 tube (it is fully functional with either length tube):



    Alternate shortened Convoy S2+ host in polished bare aluminum. I soaked an S2+ in Greased Lightning to remove the anodizing. Then to remove the final bit of green anodizing I soaked it in Clorox bleach for 6 hours. The bleach also turned the aluminum a dull dark grey. I sanded and polished off the grey from the raised portions of the light, but left it in the cracks as much as possible as it provides a nice contrast. I used a separate host from the blue, so have both hosts.

    Excellent mods fireclaw, great idea with the shortening. The s2+ when came out(guess compared to some still now) was compact for 18650. Being more use to the little Zebra's these days, the s2+ does feel quite large. Like it! and the stripped looks very
