on the A6 driver, when turbo steps down to high, a short tap will push it back up to turbo. is this UI the same way?
This isn’t the same driver as the A6, this one uses the ATTiny25 which allows for thermal regulation, so the light doesn’t step down like the A6 but instead it ramps down with 64 levels of stops.
Enter the config mode, at the 7th blink break connection during the stutter… it’ll come on in about a med mode, turn it off… this disables it. If you want to set it, wait a couple of seconds after the med mode and it will shift to Turbo where you can run it til the heat is as much or as little as you dare, turn it off at that point and this will be memorized.
I got my ss/cu with box set today. I am beyond happy! Wife thinks I’m insane because I called her into the room for the unboxing. She just shakes her head and searches for the number to a cheap psychiatrist.
My lights were perfect no issues whatsoever. The box had one little ding on one corner that I never would have seen if not for reading about that issue here. For me, no issue at all. Completely satisfied. Ecstatic.
I would like to express my thanks to all involved with this venture. I can never you repay for all your work and efforts. THANK YOU!! I look forward to being able to participate in more of these customs lights.
Cant wait to show these off!

ok thanks. i thought i noticed small step downs but couldnt prove that it was stepping down. but the 64 step downs make sense.
> Southland … clip … pliers … hammer
Sorry, I can’t figure out whether you’re joking, or describing what you actually did in a way I don’t understand.
Sounds like sticking the pliers inside the bend and hammering on the outside, which would not open up the bend, it’d make it narrower.
Would you add a picture of how you fixed your clip, if you actually did what you’re describing there?
The problem is the old familiar one, the 180 bend is so tight that folded cloth won’t fit into it.

Thanks Dale. I think I disabled it as it now seems to be running steadily in modes 3 and 4. Looks like something weird going on in there.
I'm guessing the same process (break at 7th stutter, then off at Medium) would toggle the thermal protection back ON again? I tried this but it seemed to make no difference. I can't push the light hard enough to heat up properly on the 3.2V LiFePo4 so I can't memorise a setting ATM.
Sorry to be a pain but do you have a link to the firmware instructions for this light. The diagram in the first post is helpful but lacks detail. I know it's probably buried somewhere among the nearly 5000 posts in this thread.
Cheers
It’s also in the first post, just look at the 1/22 date
Thanks myhken. Ok, so that is the same link I posted in #4983 which means I am looking at the correct instructions. (I mistook Dale's comment about it not being the same as the A6 to mean I was looking at the wrong file.)
This doesn't mention toggling thermal regulation on and off, only turning off or seting manually. If that's the case I guess I'll need to wait until I get some IMR cells to be able to turn it back on when the light gets hot?
The X5 is eating up battery power. Just played a little with it yesterday, set the thermal settings and today, I tested the thermal setting, and noticed that the lights was less brighter then yesterday from the start. Pulled the battery, and it was down to 3.3V
And that’s a protected Keeppower 840mAh. So it’s not using the full power of the light.
So not much runtime with the X5.
Not tested the X6 yet, but there I have 30Q, HG2, MJ1, GA batteries I can use.
My Keepowers are protected 800mAh - maybe 3 years old but with little use. I can't run turbo without tripping the protection. Yours must have a better circuit. Even so, you wouldn't expect "full power" on a protected cell. With such little capacity in a 14500 and this awesome driver, eating batteries will be inevitable in the higher modes.
It's a little gem of a light!
It can be that it run on full turbo, have to wait to get some IMR cells on their way before I know for sure.
Yep, the full sized FET driver on a small 700mAh cell gobbles it right up. (non protected high discharge cells in the 14500 class are ~650mAh)
When you are able to pull 5000mA (5 Amps), a 650mAh cell is being slammed! 
But it sure is nice to have big flashlight output in a palm sized little beastie that fits in a pocket easily.
So, now imagine going up to 11.5A on that little cell with a Quad. :bigsmile: I stepped outside night before last to go to the shop for a quick mod (put a tail clicky in a SupFire M6 for lockout) and was wearing my Nitecore HC50 Headlamp. The dog was acting like there was something he wanted to go after and the headlamp wasn’t showing me the far end of the yard (200’ deep) So I pulled out my little Cu X5 Quad and BAM! lit up the whole backyard ( I wear the Quad X5 in a horizontal open top Kydex holster on my belt, have had it with me ever since it came).
Bunny rabbit, stupid Yellow Lab was all excited about a lil ol bunny rabbit! As you might can imagine, that little Efest Purple 14500 isn’t going to do 3000 lumens for long, but it sure is nice to have it if/when you need it! And of course, this is what 7 levels is all about, battery level control.
My lights come in today so I’m leaving work early to meet them at the door!!
That is what I call dedication!
My wife would call it something different 
Andy? Do not look into the light! I know you will, but don’t say you weren’t warned…
Got my Al set today and they look pretty nice. I’ll have to get some better cells to push these lights to their max potential. The only issue I have is with a cracked lens on my X5. It’s only towards the edge, but I wonder if it will become a bigger issue, especially if it’s ever dropped. You can see the cracks extending past the edge of the reflector or O-ring, not sure which it is, as I don’t want to open it up and risk the cracks getting worse.

gadabout,
One of my Al X5 was doing the same or similar to yours. It corrected itself after doing a tear down, clean and lube job. Not sure of the cause, but happy it worked. There was some shavings around threads and loose around the internal components, but that is an observation, not a causal factor.
true flashaholic!
Thanks TK. Did a tear down, clean and lube. Everything tightened up nicely. Tailcaps switched and no change. I will contemplate getting a solder iron to investigate/troubleshoot more. Your suggestions are greatly appreciated.
