Since I dislike low CRI CW and since the UV light of the K3 lite is too easily activated, it got a SST-20@4000K (main, for a little more throw) and a 219B sw45k D200 because everything else is red or rosy, too.
Not a nice mod. Fitorch lived up to the RoHS regulation and used leadfree solder. Melted at approx. 230 °C Taking this apart is also not nice
Edit:
Armytek Zippy. The 5000K Nichia 219C is a little tilted. I never before reflow over a candle. May fail or not, LED swap is easy enough for a second try.
Good news for SP40 users: 219B with no beam artifacts
Don’t know if turbo is healthy for the LED, probably not, but color is still ok.
I found out the 17mm forward clicky from mountain electronics will fit a Lumintop Tool AA with some dremeling to reduce the diameter a little bit. I used an old surefire switch boot with no nub and it’s worked great so far.
Also swapped Osram W2s into a FW3A, my first emitter swap. I love the W2 emitter. Love the torch labs clips too. Their 1” clip just took a little sanding on the inner diameter to fit and the Convoy had to be drilled and tapped. The convoy next to the FW3A was modded by Skylumen with an sbt90.
Finally have a warm thrower. XPL HD 3000k in a Astrolux C8. Too lazy to slice it so it’ll stay an HD. And it’s not as warm as I thought it would be. Kinda disappointed but also happy about it.
Yes I hope he changes his mind and does more stuff like this. I would like a 21700 and a smaller battery (14500,16340,18350 maybe) “kit” with appropriately sized custom TIR heads.
For years, the first thing I did to a light when I got it was perform a “clipectomy”. After all, my standard practice was to carry my light loose in my pocket with my keys and some kleenix. A clip was just deadweight so removing it was the first thing I did.
I made an exception for a few lights. Zebralights like the SC6x series have a fixed mount with sharp corners, they’re pretty horrible without the clip. Also the FW3A clip serves as a handy anti-roll device.
However, with Covid shelter-in-place, I find myself spending more time working from home. Instead of slacks with stuffed pockets I often find myself wearing sweatpants or shorts with almost nothing in them. I found that using a pocket clip to attach my light to the outside of my pants is more comfortable than carrying it in an empty pocket. I still wear slacks and carry my light safely in my pocket if I have to leave the house, but household use the clip is really nice.
So I went around gathering pocket clips and reinstalling them in many of my favorite lights. Some hilights:
FW3A clip - extremely nice. Slips on and off easily and feels secure and low-profile.
Original D4 clip - not bad, but feels a bit flimsy.
New version D4 clip - better. Feels stronger than the original D4 clip. Works well with the 18650 tube, but not so much with the 18500 tube.
Jetbeam RRT-01 long clip - excellent. Slips on and off easily and feels secure. However, may scrape up the head when changing the battery in the 2012 model RRT-01 and TCR-01. Works well in 2019 and 2020 versions where the clip does not touch the head so no risk of damaging the finish.
Jetbeam RRT-01 short clip - excellent. Slips on and off easily and feels secure. Low profile and does not scratch up the head. Does not work well on 2019 RRT-1 since lip is too close to indent in the battery tube.
Since my 2200 mAh Vapcell 18500s arrived, I find myself using the 18500 tube on my FW3A and D4v2.
The stock FW3A clip works very well with 18500 tube.
Both versions of the D4v2 clip weren’t quite satisfactory with the D4v2. The head caused the tip to stick out and dig into my thigh when on pants or palm when held in hand. Neither were low profile.
I went through my supply of clips and tried various different ones on the D4v2 looking for one I was satisfied with. Ended up scratching up my 18500 battery tubes and the bottom of the head.
The clip that works best on the D4v2 with 18500 tube seems to be the stock FW3A clip. Installed at the back of the battery tube below the o-ring. This caused the tailcap to not make electrical contact with the body tube. This was easily fixed by installing a thin strip of copper bent into a c-ring at the bottom of the battery tube.
Taking this apart is also not nice 
10507, I think its my favorite.
