What did you mod today?

It was sort of the other way round this time.. :D

I always had the True Utility telescopic pen but wanted a titanium version, then I saw the toothpicks when searching.

I think I did invent the worlds smallest extendable titanium ferrocerium rod though :)

Since I had another Luminus SBT-90 Gen 2 to do something with, I modified my scratch built 124mm reflector light, DBC-07.

A write up on it HERE.

So now itā€™s the largest BLF Q8 ever! lol

And it easily hits a hay barn at 1.02 miles distantā€¦

I tested it with Samsung 18650ā€™s, both 35E and 25S, it makes from 4300 to 4800 lumens and a quick 5M test (too close I know but it was still daylight) shows 1.71Mcd! :smiley:

Edit: Worth mentioning that the beamshots here and on the write up were done using the 35E cells at lower output. :wink: I have new 25S cells arriving todayā€¦ the ones I tested with have been, well, Hamā€™red!

Today I put a Oslon HX Boost HL in my GT Micro. I had bad luck getting a good focus, but it still more than doubled in throw compared to the XPL-HI NW.
It out-throws the FT03 with 50.2.




Before with stock XPL HI NW:

After Oslon HX Boost HL mod

I think thatā€™s the HL.

Yes, Boost HL.


WB daylight

Another Jet II MK. Ladies and Gentlemen, this is my very first reflow :beer:

Some time ago I modded my C8 (SMO to OPR and XP-L Hi to XHP50.2, A6 driver) and was left with a very nice XP-L Hi U6-4C MCPCB. Now this LED resides on the original board of the Jetbeam. Iā€™m really proud :blush: .

Edit: Yeah, I see itā€™s not centered :weary: :person_facepalming:

Looks good to me Unheard. Congrats on your first reflow!

Thanks :slight_smile: . Now I know why I ordered some 219B :smiley: .

Mine was worse. Congrats!

TrustFire Mini-08 Electronic Tail Switch.

An amazing mod CRX!

Modded my new Tool AA V2.0 Ti:

  • Reflowed a Luxeon V2 5000K
  • Added a bleeder resistor (stock tailcap works ok without one, but not my custom tailcap - it needs a dependable current path). Used a 0603 footprint 750 Ohm resistor stacked across the main capacitor (see the yellow circle in the picture).
  • Swapped the black tailcap for a very light green GITD one (link). The only problem with these is that they donā€™t have a ā€œnubā€ inside, so you really need to press in order to activate the switch. To address this, I put a dab of clear silicone caulk in it and let it cure. Works great now. This lets a TON more light through than the stock black tailcap.
  • Stripped the stock illuminated switch board, which is a similar set up to the Convoy add-on illuminated tailcap that utilizes a clear plastic washer to let the light get to the tailcap (albeit, somewhat inefficiently).
  • Installed a battery-monitoring tailcap. It has 4 LEDs that extinguish one by one as the battery drains down.
  • Attempted to strip the gold clip, but failed. After a 30 minute bath in a strong lye solution, the coating didnā€™t budge at all. It probably is real gold plating. Itā€™ll stay for now. Iā€™ll probably either just remove the clip or grab a stainless one from another light.

Nice upgrade gchart. Is it 10440 or 14500?

Oops, itā€™s AA / 14500. I just updated the post.

Nice and skillful mod, gchart. :sunglasses:

That battery-monitoring tailcap is incredibly genious. :open_mouth: I will try to build one. I need this on my flashlights. :partying_face:

That battery tailcap, kinda want.

The HM1160 were cheap enough that I ended up buying 40 just to even out the shipping fees :person_facepalming:

Soā€¦ I could probably whip some up for folks if you know how to install them (and a bleeder resistor).

My friend use torch to de-color the clip, works well.

Btw thatā€™s a nice mod of yours :+1:

Yā€™all probably know that the X6 is one of my favorite lights, right? Like, I have some 19 of these and more than 12 different emitters in use. So today I put the 90.2 in an X6, serial number 62 in the SS/Cu Limited Edition light. Really nice look, really nice power!

Using a Samsung 25S 18650 it pulls 25.5A at the tail for 5190 lumens at start (too hot to hold in 20 seconds), makes 100.6Kcd for 651.25M throw. Me Like! :smiley:

SBT90.2 in such a small size sounds fun! Did you put it in the copper version?
