It looks great. I think I found it: Project Caerus

A similar driver is the H1-A: http://kaidomain.com/S026606-H1-A-20mm-3A-1-cell-1-Mode-or-5-Mode-Boost-...
I have seen somewhere a tutorial to use it as eSwitch driver. You have to remove the Capacitor and solder the switch wires on that points, i think.

How did you get that so perfectly centered? I have a C8 with a white flat and I can’t get it that good, and you’re even using an XM-L2 centering ring.

Thank You. It needs some tweeks. Drivers from lexel (1- -3+fet)showed up today and my MTelectronics order. Got in hurry and flashed it with the wrong version of Anduril.

Needs a few tweaks, I am having fun Big Smile

I properly focused a thrower for the first time.

Convoy C8
SMO reflector
Osram “white flat” 1mm²
MOSLED 3030 MCPCB
L4P LD-B4 driver set to 4.5A CC

I 3D printed some gasket with different base thickness to adjust the height of the reflector.

After a few try, I got about 155kCd @10m but I have to make some more precise measurement with a laser meter.

The gaskets are made of PLA which is not ideal given the high temperature but I already planned to print some ABS ones for the next batch.
Now that I saw a 25% increase in intensity I want to do the same for my Amutorch JM70 (FET driver, 2mm² White Flat but only 470kCd ATM)

I took 3 rather plain looking Idaho potatoes and turned them into a golden pile of crisp heavenly French Fries, with Sea Salt on them. My son did the high pitched Nirvana sound….

Literally modded a bunch of sh*t I picked up off of the floor into something that should turn out pretty awesome I hope. Behold the can of mystery…

Loosen the bezel a little just when I smack the head side the reflector is able to move a little. Not complete rattling just it can slip a little. I powered the light on and raised above my head pointing to the floor with loosened bezel and looked the beam and smacked the head lightly and tightened down a few times the bezel until I was happy with the result. I didn’t used glue and it only took a minute.

A teaser for now until I can write a proper post. I managed to short 2 BeCu springs so I dont have enough energy after “repairs” to go into details tonight!

This is a special one, nearly all of the parts were made possible through other forum members in one way or another.

The light that BLF built:

Host Sofirn C8F 21700 (host version avail. thanks to BLF)
Spacer Prototype AL spacer from kiriba-ru
MCPCB LED4Power 3535 ANNA6
Driver Lexel’s 21mm C8F version TA FET+N+1
includes more clearance for the retaining ring
Optic Ledil ANNA-40-7-S
Springs BlueSword’s BeCu spring
LEDs 3x LH351D 4000K 90CRI from AEDe group buy
3x LH351D 5000K 90CRI from DigiKey

Some quick measurements:

18650 VTC5D
21.x amps
5,693lm at 0s

21700 VTC6A
5,851lm at 0s

21700 30T
6,479lm at 0s
22.5 amps at ~30s

Pictures:

Sloppy re-flow I had to do twice cause I used way too much solder paste. It’s hard to “tap” excess solder from 6 LEDs, 2 pads, 1 jumper in a reasonable amount of time. Note I jumpered the FET and left off the LD-x4 specific parts (temp sensor, FET, JST connector)

The C8F usually has a small tapped screw hole in the middle which holds the reflector and MCPCB to shelf from underneath. I drilled it out with a 15/64 bit, I could have used smaller but I left it big in case I want to add larger LED wires or use the signal wires if LED4Power releases and e-switch driver some day. In this picture I have a small blue spring but I ended up turning it upside down cause I think it’s too tight to prevent shorts this way.

Don’t forget your TWO layers of thermal paste. You could use thermal adhesive but I have no balls. Also, the spacer has some play so you would want the whole stack to be centered first if you went this route. You could also hold it like this if you have trouble soldering the LED wires but I didn’t bother. Those coated pads + a big honkin chisel tip will do the job.

Since i’m using a 7 LED optic on this 6 LED board the wire placement is something you need to fiddle with. The unused center TIR caresses your wires lovingly.

In order to seat the optic all the way down the edges press right up against the head of the light. If I remove the bezel again I will probably have to wedge the TIR out with a screwdriver. If that’s the case I think I will sand the TIR slightly to give it more room. It’s terrifying screwing on the bezel snug. Everything rotates some and I worry I will either crush something or bunch up the LED wires. I did it anyway, YOLO. It survived.

I did some tint mixing since I didn’t have 6 of the LEDs I wanted to use. The beam is nice, there is a defined and very even hotspot. You would never know the middle LED was not used. I suspected as much since Ledil makes this same optic with 3-, 4-, 5-, 6- and 7-lens versions.

I had zero issues testing with various 18650’s but when I moved to 21700’s I ended up shorting something and melting a blue spring in seconds. This is when I put a new one on but this time upside down. I think my tail spring is too long and stiff also so I will play with cell spacing and refine this.

Heat doesn’t seem to be a big issue and not using DTP for the MCPCB seems fine as well. Further testing needed here as I only tested turbo in ~1m increments. The light never got too hot to hold even after several 30s-1m turbo runs with a 30T. There is a lot of mass in this thing after all.

When I first saw that picture, I couldn’t tell what it was. I was thinking maybe it was a bowl of greens and he’d taken a picture of his lunch! Wink Especially since the previously posted picture was of some french fries.

Box of washers I ordered arrived much faster than anticipated. Guess it’s time to start modding. Ughh

Goal is to:

  • file down the bottom of the washers so the bases are smaller and the washers don’t stick up so much,
  • expand the interior hole by inserting long-nosed pliers and then expanding the jaws, and
  • glue them onto side-switch flashlights around the button with Arctic Alumina to help reduce the chance of accidental pocket activation.

I ordered #14 nickel-plated brass finishing washers. Hopefully that’s what’s in the box I got (box just says “nickel”). I definitely want nickel-plated brass as the brass is easy to file and work with, while the nickel plating is durable and looks great.

Lights I have in mind for this mod are the Emisar D4 and Fireflies E07. I’ve previously done this mod using #10 nickel plated brass finishing washers on a DQG 18650 Tiny III and got fairly good results. Looks classy and worked well.

Biggest disadvantage of this mod is that if the head of the light heats up around the switch, the metal finishing washer filled with thermal adhesive is going to heat up too. This can make for ouchy on your thumb when trying to turn off the light if the ring gets too hot. A plastic finishing washer would probably be more functional but would look much, MUCH worse.

Really nice C8F mod! The ledil anna looks like a nice optic with good frontal coverage. Better than the optic used in the fireflies E07.

That’ll just cause plastic deformation and actually thicken the rest of the metal. When I make my own washers I make / enlarge the center hole with a step bit [handheld].
This was not a washer, it started off as a square I cut from a sheet of Cu. I drilled a small hole with a drill then mounted the step bit in the vise and went to town rotating the material around the stationary bit.

It works.

As you expand the jaws, the washer bends into a bean shape. But then go around to the short part of the bean and expand again. Continue going around in a circle until the washer is circular. Yes, you get plastic deformation, but when you go back around in a circle the inner edge of the washer fails to fully return to its original position and stays closer to 90 degrees vertical (compared to 45 degrees before modding).

This technique easily opens the center hole up a couple mm when done with a 10mm #10 brass finishing washer. At least that was my experience when I used this same technique on two previous DQG Tiny IIIs.

Not sure drilling is a good idea. These washers are very thin. Drilling is likely to go through the side of the washer. Also, even if it worked, drilling would remove the beautiful nickel finish.

Fairly certain Turning Blue Chips is about to turn a pile of shavings into a bar that he will then make a light from. Converting “scrap” into a nice final product. Wink
