I’ve got both a 219c and 6500k on order, I’m going to compare them to my E14 II which I believe has similar turn on power. It’s recording nearly twice as much lumens as my DQG Tiny 3th!
Excellent!!! :partying_face:
I tried to EDC the D4 in my pocket (with keys) for a few days, and am afraid it is not going to stay there. Without lock-out it fires in the pocket about twice a day (some were to moon, some a lot higher), with lockout (manual or via UI) it takes fiddling before I can use it. I use my light multiple times a day so it is sort of important to me to switch it on in a second.
So for EDC I’m back to my E2L shorty, which was tough competition for the D4 anyway 
(219BV1SW40R9080,BLFA6driver,slowdiscotail) which works great, it is a bit smaller, and a tail clicky is not just switching on by accident.
The D4 is going camping with me next week, for that it is a great allround light
But perhaps for a future firmware of the D4 a thought or two can be dedicated to how to implement a quicker lockout sequence.
I have the E14 with 219C (stock version) and it’s nowhere near as bright as the D4 (with 219C).
I experienced “hot pants” even with my short S2+Triple EDCs several times. Afterwards I changed my driver firmwares to only cycle through safe modes (in terms of heat) - unless the user double-clicks the switch. The D4 needs something like this.
And it also needs a lanyard hole and space for protected batteries.
Hi. I just ordered a couple of the D4’s. Received one of them already but it’s so small that I’m afraid that it’ll fall out of my pocket. Where can I buy pocket clips for them?
About that… and all other UI suggestions… I have a large part of the code foundation written and working already. I doubt it’ll be long before I have a “RampingIOS v3” firmware available which 1) implements all the changes which I think sound good, and 2) is dramatically easier to modify. It’s a complete from-scratch rewrite totally unlike anything else in the repository.
Just received my second D4, a green in xp-g2 3d. I really like this tint. It’s ever so slightly warmer than the nichia - a nice pale white, still very neutral though.
My only complaint is that the groove for the pocket clip came with a big scratch and the lens had lots of dust underneath. It feels like this was used, maybe a returned unit, or poor qc. Beside the cosmetics the light functions fine. I can disassemble the head and clean the lens and the groove would’ve been scratched eventually, so I’m probably not going to bother with a refund or anything.
The Convoy deep carry clips work, but beware that it might scratch the anodizing, at least it did on mine.
Any other clip that has a 3mm(max) tall collar with a 18-20mm diameter should work.
Thanks. I don’t want to scratch it so soon lol. Did you measure the dimensions with a caliper? I have one at work but I’ll have to wait until Monday.
I’d love a clip or two too, but I haven’t been very happy with any that I found yet. I may see about ordering some of those “205” style clips though, which seemed reasonably decent aside from not being deep enough.
I haven’t found anything at all which would work on the 18350 tubes, which is unfortunate since that’s the size I would most want to clip to things.
Until I can find a clip, I’m just using a zip tie and a wrist strap lol.
excellent idea with the zip tie!
I couldn’t get this one to work:
Sig P225? A-Zoom?
It’s been in my backpack for several days. Got scratches in 3 places and a tiny dent in the tail cap. Maybe it’s just me, but I don’t think it will stay in a perfect condition for long in any pocket. And so I wouldn’t bother much about scratching it with a tail clip.
OTOH DQG Tiny 4th came with a clip and I scratched the light while removing it before the 1st use. That wasn’t nice. Especially that it’s still the only damage.
djozz, twist-lockout works well for me. Though the delay until it stops blinking is sometimes annoying.
TK, you’re great.
I think this deserves repeating
Man some shoebox tests show my FET driven E2L with triple XP-G2s isn’t quite as bright as I hoped, and that as the battery drains my quad 219Cs in the D4 rapidly become twice as bright.
I carried the D4 around tonight and this thing EATS batteries. Going near turbo is just silly, but I LOVE it. I was showing some friends how it works and they started joking, “and press the button this many times for the bat signal” to which I responded by showing them the bat check logo on the UI graphic. “So what do you have to do for it to play music to you?” Told them I hadn’t figured it out that far, but it might be possible.
Lastly, I just use the physical lockout for now. It’s fairly easy, but I did find myself fiddling a bit to twist the end cap on with one hand. I don’t like pocket clips at all so that’s moot for me, however, I will try that zip tie 
will this driver alone be available ??
I believe there is mention of this a few pages back, MTN will have them available?
They joke, but … it has been done:
I see that 5 clicks hasn’t been assigned to a mode yet, this should be it.
