I used some sugru on my B158 build to hide beam ring artefacts…
It’s a really nice material to work with, but it takes a bit of practice to get it perfect

Last night I re-tested/recorded the fully modded BLF SD10 (Lumintop) with a FET+1 driver. I took off the protection circuit from a TrustFire 32650 and got incredible results with it! All measurements done with a clamp meter at the tail w/heavy gauge wire loop:
TF 32650 @4.09v: 6.67A
SAM 30Q #2 @4.21v: 6.60A
SAM 30Q #4 @4.20v: 6.53A
EFEST 26650 4000 #4 @4.22v: 7.03A
BASEN 26650 4500 #1 @4.22v: 6.82A
BASEN 26650 4500 #3 @4.22v: 6.93A
BASEN 26650 4500 #4 @4.22v: 6.89A
TF 32650 @4.22v: 7.58A
The "unprotected" TrustFire 32650 must have incredible IMR power to beat those other cells, and it beat them significantly.
With the stock XM-L2 U2 3C on a 20 mm Noctigon, and the unprotected TF 32650 @4.22v, I got:
lumens: 1734 @start, 1578 @30 secs, 43 kcd (415 meters)
Sounds like I need to find reason to use one of those 32650 cells…
Are there any other single-32650 lights out there? I sold my SD10. Maybe I’m due for a Mag-mod
TrustFire TR-A9 (where available - FastTech says in stock if you believe them ) and Lumintop SD10 (obsolete now, maybe still available somewhere). Both have issues with heat mgt, poor pill designs unfortunately, TR-A9 could be worse.
Ahhh - or have Dale make a 32650 size tube replacement for a Convoy L2 or L6, or a EE/Manker/BLF X6 
These #'s from the unprotected (ripped off) TF 32650 are pretty sic. Richard sells them already unprotected - wondering if my 32650 is "golden" or from a "golden batch" - love to see if repeatable with one from Richard.
I'll be testing my 32650 with a FET based XP-G2 light I got around - simply holding the cell to the driver spring, but want to see if I can get a good bump on XP-G2's as well - that would be the ultimate use for it. Also think'n if the BOSS1 could be adapted to 32650's - might need creative mill/lathe work of course... Dale?
I’m taking pictures as I go. I might make a build thread when I finish if the light looks ok. Right now it looks pretty beat up.
Last night I replaced the black Sugru with grey Sugru. As expected, just mixing black and white Sugru gave a neutral grey. It does not match the bronze-grey coloration of the anodizing on the light. I’m undecided if I want to buy colored Sugru and give it another shot.
Colored Sugru costs $18 a pack at the local hardware store (includes 1 packet of each of the primary colors plus black and white). $18 for one attempt with only a half-hour mixing and application time for the project sounds rather expensive.
Alternatively, I could try painting over everything except the switch button using my method with acrylic paints and super-glue. That would give me a much better color-match. But I’m not sure the paint would stick well. Sugru is a fairly hard rubber, but it’s still far more flexible than other surfaces. A little bending and flexing would cause my paint to break off.
I gotta take up fishin. Between the wife, my mom, and BLF, my Honeydo list is enormous!
A crude mod today, a hanging hook for my BLF-A6 bare 18350, made from a piece of iron. This light gets beaten up against my keys all the time, the finish does not have to be or stay pretty.
that’s pretty neat. How strong is it against deformation?
I can probably hang on to it, and if not, the aluminium will go, the hook will not deform.
How/from what exactly did you make it?
Really? How’d you do it?
It was a stiff iron pin from somewhere, chromed at first, but I heated it to orange colour with a blow torch to make the bends, then the chrome flaked off. Actually I think I could just as well have used a common nail.
That is one neat mod djozz. So simple but to me so creative. Love it.
Would that make you a chandelier? 
DQG Hobi UV & ZWB2 filter.
Xhere did you get your ZWB2 filter ? I can only found one cheap source for 20mm ones on GB…
That’s the ones i use, i carefully grind them into shape with a diamond wheel to fit.
I could use a 35mm, anyone know of one? I’ve got the Nichia NVSU333A in an X6 at ~ 3.6A.
Tonight I revisited my Jax X6 Hunter to fine tune focus from the MT-G2. Pulled the brass pill, removed the 20mm Noctigon and re-flowed 2 copper discs under a 25mm MaxToch mcpcb while mounting a new MT-G2. Using a tab off a large Omten switch, I extended the pads away from under the reflector. Now the reflector (having already been modifed with a square aperture to encompass the MT-G2 substrate) sits flat on the mcpcb and the hot spot is tight and clean. 11.5A at the tail from a pair of Basen 26650’s for 4571 lumens out the front. 
I have bought a 30mm ZWB2 filter on Aliexpress (for a UV led test rig), but have not seen 35mm yet.
