I think Tool AAA uses a constant current driver? not PWM controlled.
The 2-mode Tool that Selfbuilt tested more than a year ago was current controlled, the newer model 3-mode Tool that I tested half a year ago was PWM controlled, with a fairly low frequency. So Lumintop changed that at some point.
It would be great of course if this copper GB Tool would use current control for the three modes, but I guess that would imply a new driver design by Lumintop.
(btw, if this gb works out with this 0.5%-20%-100% driver (PWM or current controlled), I would be interested in a couple of separate drivers for modding, if that could be arranged :-) )
Thanks for the tips, wasn't aware that there are 2 different ones. Will ask them to use CC instead of PWM.
Might ask them to make some spare drivers too.
good, I hope it works
fwiw, the Copper Tool looks and acts just like a Maratac Rev3, which uses PWM and has a 40-1.5-132 lumen sequence with XP-G2. Even the pocket clip matches.
My bet is all the parts are already made, we wont have a choice of driver, it will be PWM M-L-H… now prove me wrong please! Im impressed that the BLF Tool WILL have a Nichia… I LIKE!
And, IF this copper tool gets a no PWM circuit and Nichia, Im guessing the next Maratac will offer those as well.
so, Kudos! for pushing Lumintop in a no PWM, yes High CRI direction…
Didn’t the CC two mode tool only work with NiMH vs. PWM three mode tool for both Lithium and NiMH?
Two mode was very efficient but not as bright or adaptable at three mode.
I would like ” Two ” of these…
Thanks
Thanks for doing this. 
FWIW, my lumen calculator says that even mode spacing would be:
- 0.5 lm - 20 lm - 100 lm
- - or -
- 0.5 lm - 9 lm - 38 lm - 100 lm
I prefer the 4-mode spacing, but it looks like the 3-mode version is leading the poll right now. In that case, there is perhaps no change needed.
Its very difficult to please everybody, but .5 lumens is a setting that would be too low IMO.
Consider that the .5 lumen setting is not a usable amount of light for 99% of the time (perhaps even greater than that). The light will come on in a mode that is useless for 99% of the time? It just doesn’t make sense.
AAA lights are best with 3 or fewer modes, and I think that the poll proves most people agree with that. Again we all want what we feel is our own vision of the perfect light, but simpler is better IMO.
The original tool had a low of ~1.5lm and a high of ~70lm. If you could get the low to be anywhere above 1lm, the med to be somewhere around 18-25lm, and the high to be the highest lm you can get at least 1hr of regulated output with an Eneloop - That would be perfection.
You have chosen the best emitter, the best clicky AAA body, and what I believe is the best 3 mode circuit in all of AAA lights. I’m sure whatever you decide, the modes will get the same consideration.
You’re right, it’s hard to please everyone. I find 0.5 lm a bit on the bright side. 
But seriously, I’ve been trying to figure out what people can agree on and what they can’t, and I think moon is one of those things people will never agree on.
When you switch one word in a statement, attributed to Abraham Lincoln, you get:
‘You can please all the people some of the time and some of the people all the time, but you cannot please all the people all the time.’
+1. I love the Zebralight & Thrunite moonlight/firefly modes in the middle of the night, and 0.5l seems quite bright. No biggie though, horses for courses.
I like a 1 lumen low like the xeno Es1 has ,it's bright enough to read by and yet when you turn the light on to go to the bathroom at night etc it doesn't hurt your eyes . My definition of a decent low low is one that actually works ..not one that impresses you about how low you "can go" .
i have about 5 lights that have 1 lumen lows and although i've been a fan of the zebralight lows, i think one lumen is a smarter choice than the really low moons .
some moon modes are just too low to serve any purpose unless you're trapped for 100 days in a cave . If thats the case you deserve to die for bringing a AAA light.
a half a lumen is a nice moon mode imo
I agree. And it does not need to come first. The thrunite pattern, starting on .04 lum is silly to put first. It is the least likely brightness needed for most uses. I always have to skip past the thrunite moon first mode.
And the moon is waaay too dim for most uses.
I’ve come to prefer MLH. IMO 20-100-.5 would make most practical edc
I completely agree. 20 100 .5 or 1 please.
Not for me. L-m-h only. Prefer around 1 - 3 lumens if it’s only 3 modes
Im flexible, L-M-H with 1-20-100, or .5-20-100 can work fine. Stoked about the N219, hoping the PWM can be avoided, but even that is not a deal breaker.
A copper Clickie Maratac lego sounds all good to me! Thanks to everyone that got it together… Ill take one and try to stop turbo posting
The 3 modes won, even they are really close. Many people could like it,some might live with it too,while some might give up. Thank you.
Let's go for it and end the endless discussion.
I second the motion.
How about 1-20-100 for 3 mode? Start with 1-3 lumens? Can we all agree to that?
We don't know yet whether .5% gives a low below 1lumens..
Maybe it's 1lumens, maybe more, maybe less.
It should first be checked/reviewed/measured, every new flashlight should be carefully checked before it goes into mass production.
