I think you have some dirty threads or something, when I unscrew the head a bit when the light is on, it stays on but disables the switch. Of course when a electrical disconnection occurs for a very short time during the unscrewing action , the light will go out.

As proposed in other FW3A topic, the behavior difference may be due to presence of lube on the threads. Given the initial contact trouble I had with mine out of the box, which cleared up with a few loosen/tighten movements. I’m guessing that this action pushed away enough lube to make a good contact but then breaks contact with a slight rotation of the tail cap, instead of maintaining current flow for up to 3 full loosening turns.

I’m already abusing this light even more than I had planned to… Evil

Now running 2x stock XP-L HI 3D and 1x LH351D 5000K sliced. Output and throw kept pretty intact from the 2 XPLs while the 351D definitely helps the temp and tint a bit for my preferences.

Can only really compare the brightness of each individual emitter on the very low end of the ramp but from the tests I’ve seen the Vf on these should actually be pretty similar. Frosted lens means I can only see differences in temp/tint with the light an inch or less from a white surface.

The LH351Ds are 70CRI, correct? Then, yes, the VF is pretty similar.

No. Dogfarts are a very specific product… Samsung LH351D SPHWHTL3DA0GF4RTS6. They’re 90 CRI, not 70 CRI.

Nope, 90CRI “DOGFARTS” and now I realize the Vf/current charts I was looking at were actually for LH351 C so back to the drawing board I guess.

Yeah, the LH351Ds 90CRI have quite the lower VF.

Didn’t notice the DOGFARTS.

Just some GITD tape. No, I didn’t coat the light in black — it’s still gray (just a lighting trick due to contrast balance to show GITD tape). Wink

At first I had a wider band on the tube, then shortened it… and now I’m thinking I may narrow the tube strip to match the width of the tail cap strip, or take it off altogether (leaving just the tail cap). The tail cap one was cut to fit nicely in the groove, so no concern of handling that might dislodge it.

EDIT:
Yeah, thinner is better.

Also discovered that 1 strip is more aesthetically pleasing:

I modded mine, even more than I really wanted to but one thing lead to another.

I put a LED4Power triple MCPCB in (1.5mm) with 3x Nichia 219B. I replaced the wires with 20G and reflashed the light with TK’s 219B version of Anduril. I also installed a drilled optic with 3x orange trits.

Some modding tips for this light:

My LED4Power triple MCPCB had to be VERY lightly sanded. The flat edges of the MCPCB stuck out just enough to not want to drop in. I used 1000 grit and it took like 2 minutes to just smooth those edges.

I tried to use the stock wires but they are cut to the exact length the stock MCPCB needs and my positive lead could not reach the pad. If you replace the MCPCB have a contingency plan to replace the wires too if they don’t reach!

When you take the driver out you will see the LED wires are right next to each other dead center on the board. When I went to de-solder the negative lead it’s hard to get my usual chisel tip in there and I ended up pulling up the pad just a little as the wire came free. So maybe use extra flux and a smaller tip you have one. Clean it with a toothbrush and alcohol after.

When you re-solder the leads they need to be straight up. The driver sits right against the shelf so you wont be able to tuck them anywhere and if they wick too much solder cause you used a too fat tip like me then it wont want to sit flush and feed through the hole. I had to re-solder mine a second time and make sure they were straight up and down.

The LED positive wire sits a bit close to the MCU. I was still able to fit the clip on with my larger 20G wire in place but it was resting against it and just barely had room.


On an separate note, can someone try to torch/bake this anno to see what color is changes to? Take one for the team Smile

Thanks! It’s the cheapest, fastest mod you could probably do. Wink I’d like to do a GITD optic insert, but sometime later on.

^ Thanks, CRX! Thumbs Up Btw, the manual Toykeeper authored, in full ASCII text.

Anduril is a terrific UI. I was impressed by NarsilM when I got my S43, but now I prefer Anduril. I didn’t realize we can configure the ramping step intensities. The default has too much of a jump up from moonlight, so it’ll be good to adjust that.

do you have any comparison pics of how the light looks with the gaskets?
also could I talk you into making a teal one (50/50 blue + green powders)?

In the centre picture, top right is 50/50 green & blue.
In the right hand picture, bottom left is 50/50 green & blue.
Hard to see a difference as there isn’t much but it’s there.
Got Red & Orange glow powder on the way.
No comparison pics in lights, might be some soon.

Do you have to solder your wires really flat or does it not really matter? For example, is there plenty of room and will it noticeably look tilted?

I’ll probably grab an orange off you if it turns out nice. That’s what I used for my drilled optics, 3x orange trits

in that case I’ll take one of the 50/50,
any plans for a “swirl” version with green/red or blue/orange?

The wires need to be flat, the gaskets should be comfortable up to 20AWG but can be modified for thicker wires.
You can sand them down or enlarge the optic holes.

A swirl pattern wouldn’t really be possible due to the way they are made but a splodge pattern might work Smile

Actually you might be able to make one with a swirl pattern.
  • Make a completely flat disk of glow material with no cutouts. When you pour the material for this disk add the other color and swirl it a bit for pattern. Cure.
  • Then use one of the other glow disks with the cutouts as a template. Lay it on the swirl disk and use a pencil to outline all the holes.
  • Use a drill and hand file to make the cutouts.

Would take a lot of effort though.

as my light hasn’t even shipped yet compatibility is the least of my concerns right now XD
I’m still trying to figure out if I should order a new board from mtn electronics or if it’s even worth it.

I was sure that 219c’s were what I wanted but now I don’t even know, I just don’t want to have to learn how to reflow led’s so gaskets is what I’m getting

Yeah the reason I use the mould is because I don’t have a drill press & doing it freehand is difficult, might try it though.

I don’t have a drill press either.

For freehand, it might work best to make the drilled holes slightly too small. Then use a round needle-file to grind them by hand to the correct size.

I know. Doing that for myself is fine but I can’t spend two hours on each one filing etc and sell them for £6 Big Smile
They take about 45min each as is.

I just found an easy little mod, which costs next to nothing, comes in thousands of colours/thicknesses etc (including GITD) and which also protect your lights! (any really not just this one)
I vape and on my tank to stop it smashing are what are called ‘vape bands’ basically a silicone band – it fits this light perfectly! The ones I have don’t glow, but do look kinda cool imo!
Obviously I’m going to order some GITD ones, so thought I’d share the idea with you!
If this of interest just search ebay or any Chinese shop for ‘vape band’ or add ‘glow’ to it for gitd ones, they come in different widths too.

A ‘plain’ gitd one – link

I don’t know about different sizes, but they stretch easily though – they may well do different sizes, they certainly do different widths most seem to be 21×10mm. As for ‘anti roll’ shapes, again very likely with a bit of searching, they definitely do ones with lanyard holes on the side (would also stop rolling), I saw those whilst browsing earlier!
I have been googling – vape ring, vape sleeve, vape pouch, vape case …… Facepalm
maybe we should have some custom printed ‘BLF’ ones….Neal! Cool
These look interesting -

It is counterintuitive to have “Click & Hold” and “Click – Hold” mean different things.

Hold means keeping doing the previous action.

These should all mean the same thing:
Click & Hold
Click – Hold
Click and Hold
Click then Hold

= click, do not release, keep holding

“Double Click &/-/and/then Hold” would mean click, release, click again very soon, keep holding.

edit: TK’s original chart isn’t exactly like this either. In it hold means click and hold but at least that’s obvious unlike this & – and then business Smile
