Mine came today, what a fantastic light! One question: there are three flashes when ramping up/down. The second two appear to correspond to the max of the two regulated channels. The first one happens right after moonlight—what does it signify?
According to the literature, that first flash is a “subtle blink to provide a timing hint if you want to stay” at moonlight.
Strange. A quarter turn of the head, turns mine off completely. So it’s not supposed to do that?
Hhmm, I think the 1/4 turn is just disconnecting the switch, which may result in turning the light OFF. The batt- power is still going to the driver via the un-anodized threads, and the batt+ power is still there as long as the batt makes contact to the driver spring.
I think this is what TK is describing.
I just turned the light ON, and unthreaded the head and it took a few full turns, but way before the light went out, the switch stopped working, so mine works differently from yours.
Hmmm breaking contact with the springs…what battery are you running…
Anyone interested in a diffuser or two?
Printing some for a few people, thought I’d see if maybe anyone else wants some and doesn’t have a printer around.
Price is $1.50 each, plus whatever shipping costs to mail a 4x4x2 box from 54140 to your zip code.
I have these colors available,
plus a clear-ish that I have to properly dry before printing again:
I’ll take a clear & orange please. I’ll send you a PM. 
I’ll take a Clear, Orange and Blue please…. the FW4A has a bit more Candle/Lightning volume than the triple, so your diffusers will come in handy, me thinks…thank you!
Just a standard LG HG2 flat top. This is what my battery tube looks like.
Hm. Thanks for the investigations, y’all.
I like to use a paint-stick marker to put dots on my lights to make it easy to see when the parts have been turned in “on” and “lockout” positions.
So figuring it out for sure is helpful.
Weird, both mine need the head almost off before they cut off. The tail cap shuts off at a slight turn which would be normal. Is your driver spring off center or maybe the first coil cantered where simply turning it runs the spring to the shoulder of the battery, breaking contact…
Edit: My tail cap spring is soldered on, off centered and the whole spring/coil leans to one side, thats why I wondered about your driver spring?
I don’t know what normal is supposed to look like. Everything looks centered to me. I’m certainly not complaining, and use the 4 click lockout myself. Love the momentary moonlight in lockout.
With a 30Q BT it takes just over 3 full turns to disconnect the battery on mine. FT IS 1/4 turn less.
The head is about to fall off, it has less than 3/4 turn before comes off the tube.
Tailcap of mine takes about 1/4 turn to lock out.
On this light:
- Head is not a viable option for mechanical lockout
- Tailcap will work but is not a good option at all imo
Solution:
- Use Electronic lockout
The end… :+1:
Makes me wonder if the driver is losing contact now… I would think the light should stay on as long as contact between the springs is made and the bare non anodized threads…the tube is just a signal sender… me thinks… as long as the battery is in contact with the springs the MCU should be powered, just not receiving the signal, with the loss of contact from the tube, like in my case?
Hey guys. Just got my lights. Sweet little package! Is this battery cool to use?
Efest imr 18650 3500 mAh 20A 3.7V
Thanks!
Yes, it will work well.
However, it is a 3500mAh 10A cell, not 20A.
RobertB is definitely somehow cutting power to the driver (you can tell by the blip it does when getting connected to the battery again).
On another note, frankly I’m too tired right now to look through the code, but is the fancy lock-out moon mode implemented in this version of Anduril? As in, doing a “tap-hold” while in lockout?
I turned that on for my customized version of Anduril for my D4 and while true moon mode really only is useful to me when it’s otherwise pitch black, the second level is really useful when quickly wanting to look into a bag for example
I checked the retaining ring and it’s tight. The light works perfect. I guess I got a special mode… lol
Yes, it’s very handy
Mmm K… Now I want one!
