Changes compared to the previous version of RampingIOS V3:
Added a moon timing hint. When doing a hold from off, this blinks when passing the threshold between “click” and “hold”, to indicate when to let go for moon.
Better timing consistency on hold-from-off. (before, the stepped ramp took an extra 0.4s to start ramping up)
Fixed a bug where changing ramp style could go to the wrong brightness level. (go to a med mode, turn off, hold for moon, click 3X to change ramp styles, and it’d go to the med mode instead of staying at moon)
Added a D4-219C build target. (FET ramp power reduced to 80%)

Wasnt able to reset password. New problem. The light had problem with switching off after got warm, and had been turning on often, but last time it just couldnt turn off so i had to twist head off. I contacted hank but he only said to take bezel off and look there for some screws, but i dont even know what bits to buy, are they philips or waht. This being asked, hank evaporated disappear. Very pity that i actually sent him the whole amount too fast.
Said:
Looks like there is short somewhere, would you please unscrew the bezel, take
the optic out, then try to take those two screws out, and see if it will work fine again.
But when the screws are not there, please use the low mode only, not the turbo mode.
If the light is stuck at a bright mode and won’t turn off, it generally indicates one of two problems:
There is an unintended connection somewhere, allowing power to bypass the driver entirely. If this is true, then the light should act like a 1-mode twisty — tightening the tailcap would turn the light on at a very high level, without even pressing the button.
A button wire is broken or shorted or disconnected. If tightening the tailcap causes the light to blink then turn off, but it doesn’t respond to button presses, this is probably the issue.
There was a week long holiday in China. Everyone is just getting back to work.
Most flashlights are easy to take apart. I’m sure someone here can walk you through opening up a D4 if you ask. It is probably somewhere in this thread..
Yeah, not sure who that is, but it seems the account was created just to complain about the guy who runs Emisar.
What Hank said was probably correct, and is likely a useful answer. Sounds like something broke, and it’s one of two types of electrical shorts. It should be relatively easy to fix.
To add to the list of possible reasons a light would fail to respond to clicks and exit turbo mode, my friends D4 did the same thing after I accidentally popped off the R5 and R4 resistors while disassembling for an Anduril flash. We managed to get R5 back on, and we thought we got R4 back on as well, but it only looked like a good connection, actually it was open circuit.
With R4 essentially unpopulated, the light seemed to run fine, except it would not enter any strobe modes, and once you entered turbo, the only way to exit was to disconnect power. Very strange. According to zeroflow, “R4: MOSFET current-limit”. So this would seem to make sense?
Who knows. I fixed the connection properly and it’s back to normal now. Just thought I’d chime in with my experience.

Seems to me it was ToyKeeper that started the tint mixing thing with her Terminator.
I also did it years ago with a ridiculous Quad XHP-50 set up in a Lucky Sun D80. Very neat look, had to keep it reduced using 2 18350’s as with 2 18650’s it’d make the light too hot to hold in mere seconds.
This was one mighty fine little light. Got mine today and I’ve played some with it. Only problem I see is that it ramps very quickly down from high levels since it get hot.
I also read a thread on laser forum where a guy got a 1watt laser into his eye and got permanent damage. This sounds really scary and I got to think of dangers with powerful flashlights like this and kids. Is it safe to let my kiddo use this? She’s 4 and really liked this little light, told here to not touch the button on it and use it at the level I set for now and I’m watching all the time. Am I paranoid?

No you shouldn’t give this light to kids. My daughter is 7 and is not allowed to play with my D4 and other hot rods.

My nephew is 4 and is not allowed to touch my D4. His father does not let him touch his D4 either. He has his own little AA LED light that he uses and feels like it’s the same as ours.
Too much potential damage to skin, eyes, furniture, etc, in my humble opinion.
Ooh nice! I’ve been thinking of doing this, but with 3 4000k nichias, and one 3000k Nichia, just to bring it down a little. Thoughts?
I would do 2+2, I doubt that you would see a difference with only one 3000K in the herd.

I love it, SST20 have a small die so you gain some throw compared with 219C or worse, LH351D.
I’ve tested both, and the SST20 are my favorites, because of the gain in throw.
The tint mix is really nice, but I already like both tints so it’s not really a surprise

Hmm, maybe not. I think I’m gonna try it though, mostly because I only have four Nichias to my name, 3 4000ks and a 3000k. There’s a fourth 4000k in my buddies H03 that I’m gonna swap for a LH351D next time I see him, but that won’t be for several weeks. I really want a nichia D4, the D4 was my first light that I got before I knew what tint I wanted, so it’s a 6500k xpl-hi, no gracias lol.
Would a convoy s2 be weak enough? It needs to use rechargeable batteries and I have lots of 18650 around.
Is there more info about eye damage from powerful flashlights around here?
Some degree of trust is required, of course. People can’t even go outside without being exposed to something dangerous. I mean, some kids stare at the sun just because they can. So this is really something you have to determine on your own, based on how trustworthy your child is.
Almost any LED can cause eye damage if it’s running at more than a few milliamps. Staring at a modern LED is a lot like staring at the sun. And almost any battery can start a fire if the user shorts it to itself or something. So I can’t really say any flashlight is 100% safe.
A S2+ with a 3×7135 driver (or, even better, 1×7135 driver) is a lot harder to cause damage with. However, I’d suggest going even smaller if possible. Maybe something with a single AA or AAA Eneloop battery at first.
OTOH, a parent’s job isn’t to protect their child from the world, but rather, to help their child explore the world. If they make a mistake and start a fire or hurt themselves or something, it’s not necessarily a bad thing, as long as the damage isn’t permanent. It may help them learn caution. Making mistakes is one of the fastest ways to learn, as long as the mistakes aren’t too big to recover from.
TL;DR: It really depends on what kind of person your child is.
I notice that the Ti version is out of stock on Hank’s store, so maybe it is nearing the time for a new model/revision?
I would very much like another D4 but not until it gets the newer RampingOS V3
I think black (alu) body with the copper head would look amazing and hopefully not as expensive as the Ti model.
I don’t know if that will happen, but I sent Hank updated firmware today.

“just an office worker”, we all started somewhere, the first step is to realize you aren’t “just” anything… your potential is unlimited.
Its good but no time

No you shouldn’t give this light to kids. My daughter is 7 and is not allowed to play with my D4 and other hot rods.
I wouldn’t leave this light with my coworkers. There worse than kids.
Its the right size for a kid but has grandpa power. Must be respected.

Probably not. If she is an exceptionally cautious child, then maybe… but that would be pretty rare. Many adults can’t even use a D4 safely.
Start with something safer, and let her work her way up to more powerful items as she demonstrates she is responsible enough to use them.
Hmm, maybe not. I think I’m gonna try it though, mostly because I only have four Nichias to my name, 3 4000ks and a 3000k.
