This morning, I crimped some gold, flat speaker pins onto a short length of 14 gauge Monster Cable and terminated the other end with dual banana plugs. Plugged them in to my old Craftsman 82082 DMM and the light tested at 11.9A. I see the light… and now the numbers too! :+1:
Version B from my MH12. As you can tell, it’s a little too thick for the groove but it works well enough for me so I’ve been using it for the past week. Other versions might fit into the groove. There’s not a sharp edge on this clip and it’s pretty heavy duty. Been on my work MH12 for about a year. Really deep carry on the D4. It sits about a 1/16 of an inch lower than the battery cap.
hmmm … 
Not quite right … still hunting
There are also rings on threaded posts which, if trimmed, might thread into a tapped hole on the tailcap.
Spare tailcaps would be very handy to fiddle with, if available.
I wish I could find a smaller version of this tripod-thread ring:
Any idea why Hank decided to use the V2 XP-L HI instead of V3? Doesn’t make any sense to me.
Hank, not quite the same, but would a lanyard on a pocket clip work? That way you’d have both options. That’s what I intend to try, but the pocket clip is the most important option. My lanyard will be a finger lanyard on a light this small (I hope). I’ll need to play with it to see what I can come up with.
Sorry about the photobucket pix. I hope they go bankrupt (and they are in danger of that, whoopppee!) .
I don’t want to wrap the flashlight in insulating nylon cord to attach a lanyard.
If I can get a ring onto it somehow, that’d work fine, I use the little spring “lobster claw” clips a lot attached by split rings to flashlights that have the little hole drilled (or I drill the hole … hmmm ….)
The Solarforce belt clips all have little openings suitable to attach a split ring. Usually I attach glow-in-the-dark keyfobs that way (hat tip to Andygold who made them for a while).
That Nitecore clip looks close, but the arms are a little too wide and the place where the arms meet has an extra tongue thing to catch fabric on. It might be about right after some minor adjustments.
Do the fingers stick out far enough to get in the way?
I’d guess that’s a (poor) attempt to solve the problem you’d get without that extra tongue thing — the right angle connection between the legs and body parts snags fabric in my experience with Convoy’s clips.
I have one clip that makes that transition a smooth curve that feeds the fabric or belt edge into the narrower part of the gap smoothly. It came on an Orcatorch T11:
Here’s another look:
It’s solved that cloth-catching problem nicely. I wish they had several sizes and sold them seperately but, no.
That tongue-free design is the same as I’ve seen on recent Olight clips (S-Mini). Their older ones have been pretty nice too though. I’m hoping one of these might fit:
(not sure if image matches actual product; they use the same image for several different clips)

Oh boy. Thanks for heads up rubatone! I’ll be looking for TK’s review and some other comparisons. Wonder if they’ll lego? Tubes look identical.
Olight clip won’t works on D4. Leg is too thick for D4’s groove & it is taller than D4 tailcap.
Hi TK. Did Hank decide to adopt any of your updates to the new D1’s UI, or is that still in the works? 
noboneshotdog: No news yet. I still need to try some ideas for better thermal regulation though, and perhaps some other little details, before I’ll consider it ready.
So the D1’s that are shipping in the next few days will have the “D4 V2” UI correct?
Yes, as far as I’m aware, the D1 will have the same firmware as the D4 v2.
Hello
I’m still searching for good holster for this FL. Holster for astrolux s41 is too big, also holster for convoy s2+.
Do you know any other holster that will be good fit for this FL.
Thank you
Kind regards

The following holster fits very good with 18650 tube: http://kaidomain.com/p/S008608.Ultrafire-Nylon-Flashlight-Holster-11_5cm-x-2_5cm-Black
