What did you mod today?

Yes, it was originally made for CUTE optics but he is also modifying them and adding a spacer for ANNA optics if you prefer. He also “foybezeled” for me for a small fee since I don’t have a suitable grinder.

! !

My HDS clicky. Reflector bored out, heatsink thermal epoxied in. Triple Nichia 219b sw40. Dr Jones h17f driver. Reverse clicky in place of the original e-switch. Thinking about potting the driver with thermal pad and epoxy for an extra sense of completeness. This is definitely my favorite mod so far

! !
Also finished in the past couple days: Novatac quad sst-20 3500k, 20mm LD-A4 6 amp driver, new glass lens, spring bypassed, etc. Packed full with thermal pad supposedly 12 W/.

18350 s2+ 219b sw45k h17f. Ano stripped and polished because I hate the color but no pics of that yet

I finally got around to replacing the XP-L2 emitters I had put in my Dad’s Q8. It now has an LED4Power conversion board and 4 3V XHP-50.2’s. With aging 30Q’s charged up it showed 12,100 lumens out the front. I have spring bypasses done, and the tail PCB is screwed down with brass screws. While doing the emitter swap I also replaced the factory MOSFET with an Vishay-Dale SIR404DP. Pretty sure newer cells, or hotter cells, would get me up over 14,000 lumens, but hey, at some point I’ve gotta quit buying stuff! :stuck_out_tongue:

I've been using last years BLF contest winning light a lot more recently and did some more tweaking to it..

I made a new triform lighted momentary tail switch cover, dual o-rings/ copper body section and added a seventh moonlight mode for seven modes in rotary tail action and direct drive momentary tail switch.

CRX Rotary revised runtime graph in Modes 1 & 2.

My three favorites, the CRX carbon fibre, titanium & copper triumvirate flashlight set.

I guess this is half success and half fail. Got a new bezel for this light and figured I might as well change up some things…

E07 Ti+Cu LED swap

  • LH351D 3500K x3, 5000K x4 sliced
  • Added in some red aux LEDs
  • Failed to flash driver with pogo pins, could never get it to test OK even though I had aux board desoldered
  • Too scared to push driver out so I didn’t get to flash it like I wanted
  • Tint is nice already and according to SKV89 changing to UCL lens gets you 0.0020 Duv less which I haven’t done (yet)

Turbo: 5,320lm @ 3s

Anyone know why the phosphor is discolored a bit on 2 of those 3 warmer LEDs? I ran turbo several times and it doesn’t appear to be getting any worse. Whatever it is it can’t be good.

Stepped ramp measurements:

Ambient = 25.6 Lux, CCT = 3812K (Duv –0.0002)
Color Rendering Index (Ra) = 94.3 [ R9 = 69.7 ]

Ambient = 165.1 Lux, CCT = 3875K (Duv –0.0000)
Color Rendering Index (Ra) = 94.3 [ R9 = 70.5 ]

Ambient = 570.7 Lux, CCT = 3893K (Duv 0.0000)
Color Rendering Index (Ra) = 94.3 [ R9 = 70.4 ]

Ambient = 1447.6 Lux, CCT = 3892K (Duv 0.0000)
Color Rendering Index (Ra) = 94.2 [ R9 = 70.2 ]

Ambient = 3083.4 Lux, CCT = 3900K (Duv –0.0000)
Color Rendering Index (Ra) = 94.2 [ R9 = 70.2 ]

Ambient = 5462.6 Lux, CCT = 3971K (Duv 0.0006)
Color Rendering Index (Ra) = 93.3 [ R9 = 67.0 ]

Ambient = 13028.6 Lux, CCT = 4073K (Duv 0.0012)
Color Rendering Index (Ra) = 92.2 [ R9 = 63.0 ]

Ambient = 43541.7 Lux, CCT = 4146K (Duv –0.0001)
Color Rendering Index (Ra) = 91.6 [ R9 = 59.2 ]

Could be some contact from the TIR causing dome separation, I’ve had that problem before doing this mod.

My first E07 didn’t have any issues but it is a pretty close fit. Guess I need to fix it then

The two loops on the head strap of the Sofirn SP40 are too tight and in addition too far away from each other for the short 18350 battery tube. So I fixed it with a knife and double sided velcro straps:

I hope the silicone doesn’t tear where I cut it.

You were right Dale. Opened it up and you could see a slight cut on the dome. I tried to re-do it and even made the optic legs a bit tighter fit with kapton tape and it didn’t matter. One looks just the same and the other looks slightly better now. Going to have to stay like that

I think your Velcro solution is a good one! :+1:

I haven’t tried with silicone, but I’ve had many successes in using a small hole drilled at the ends of a crack or split to prevent it from spreading in plastic materials. Something like this:


Next time, drill a small hole at each end of your planned cut before slicing.

You could try adding a small hole at each end of your cuts now, but that might be difficult.

If you end up needing a replacement, consider a ZebraLight headband. They are available separately on their site. I have several of their 18650 headbands and haven’t had a failure yet.

I just measured one and it is about 20.5mm diameter without a light inserted.

Punching a hole is better at preventing tears than drilling.

Good point!

Punching a hole in silicone sounds much better than attempting to drill through silicone.

You can drill through silicone no problem.

It’ll take a lot of time though, like plastic.

Very small drill bit —————————————————————— The size you want

Looks like neoprene so a punch would be more clean. A hot nail can sear the material and fuse it to harden it but that gets tricky.

On closer look it’s hard to say what that is from the photo, but a spent .22LR cartridge makes a nice punch for that hole…

I tried drilling it in the first place (was easy), but there was no difference compared to a simple cut. Punching sounds better indeed. Will try it later today.

Technically: you’re probably right

Legally: we’re talking about Northern Europe!

cheali is the best for the four button chargers. it simply works! nice mod

Henk4U2, I forget that the world over doesn’t have .22LR everywhere. Seems like you can buy them at lemonade stands around these parts… (that IS an exaggeration but they are quite common and can be bought here in some of the strangest places, seems like everybody I know was shooting .22’s since childhood)

Not sure what would be ideal then for a punch. But the punched clean cut hole does indeed help keep a cut from tearing on the ends. Works well in leather too. A leather punch?

Some of the Mom and Pop stores around here still have 22lr behind the counter —- Use to be very common around here
