The titanium 2.0 AA version has a regular clicky. I’m actually a big fan of the e-switch. It’s unique and works well for me.
Maratac Cu AAA Rev.2 circa summer 2012. Two perfect modes: dim (~1.5 lum.) and “bright enough” ~70 lumens. Perfect regulation and near-class leading efficiency.
Manufacturers have pushed AAA drivers too hard the past 6 years or so IMO, and efficiency has taken a back seat to peak output.
Good to know, I have a barely used red one with added clicky. Might be worth buying some new 10440s for.
Disappointment there isn’t any lower than 4000k. I will mod my aaa lights with sst20 2700k by myself.
For Aesthetics.
Beam colour and feel in hand. x 200% on most others.
The Astrolux AO1 219B or c.
For ugliness and wierd shape. The Tool AAA.
End switch. Twisty and end cap circuit breaker??.
Nicely Bright.
but a wierd blend of multiple controls…
For Just being my fav Small Copper light,
My O’Light i3T EOS Copper.
Weighty. Great Shape and beautiful blended copper shades.
NOT órrible and shiny bright. Yuk…
With my Jetbeam Jet-1 MK Pro,
Still being the fav of my AA’s.
I really like the Wuben E01. It’s what I always EDC regardless if I have an 18650 light with me. No memory, always starts on low. Only thing I hate about it is 2 quick taps goes to SOS mode so you can’t change modes very quickly. It’s basically a Tool AAA with a different UI. It really needs a dc fix though even with an emitter swap IMHO.
My favorite host is the Cu Tool
My favorite LED during the day is the sw45k on the right
At night my favorite is the 3500k E21a on the left
I spent a lot of time with 219b 4000k, in the middle, but now I dont use it and prefer the other two
Agree with the BLF 348 in 219b. Plus 2 x Singfire.
Same light but Cree led’s. Colder white.
Still nice though.
Hey.
They ALL nice.
Nice :+1: 
1. Lumintop IYP07
2. Manker e02
3. Reylight mini Pineapple Gen.1
So the EDC01 can run longer at higher brightness compared to C01S?
I don’t really have a favourite in the AAA section, but this one is in my watchpocket for weeks now.
And now that I carry it lens up, I never have accidental activations anymore.
very nicely textured photo
thought it was a brass Tool, til I noticed the ring in the head…
curious about the rose colored lens?
thanks for the counter intuitive, no false activation tip
obligatory favorite
It has a 3000k sst-20 with a Lee zircon minus green filter.
Seemingly by my very amateur runtime test. There could have been slight variances in batteries as I don’t have an analyzing charger to find out. I don’t know why it was able to run longer than the tool AAA since they to have the exact same LEGO-able head and same emitter—not sure about the internals though. I would be interested in seeing other runtime graphs.
Strange… It does not look anything close to brass on my computer. Maybe you should calibrate your monitor or remove those sunglasses? 
I don’t know how many people still want C01 with 5mm HCRI led
With a BLFer’s help, I have the resource of another 5mm HCRI led which seems to be great too.
But I don’t know if you want it again.
The 5mm led has two options 3400K and 5800K. The body color of C01 can be Black, Red, Blue, DesertTan, Green, Orange, Bare-Aluminum
Maybe it can be 5000pcs in total. It can be fulfilled if only there are enough interests.
I believe there is still strong interest for both CCT.
it would be helpful to know the R9 and DUV, of the new LEDs compared to the Yuji, which are some of the best in tint and CRI. I also really like the beam they produce
you made a lot of people happy with those, I think you could do it again if the new LED is similar in tint, cri, and beam …
btw, I am a strong proponent of NOT polishing the reflector, I prefer the Original C01 beam that had NO hotspot…
If you are familiar with 47s, only their 1st (and possibly 2nd) generation Preon P1s will accommodate the 10440. Check for voltage range in specs if able. And be mindful of overheating. Use on high briefly. Sorry for my slow response - I’ve been away for awhile.
The C01 is my favorite AAA flashlight. The light is gentle, pretty, and just right for cozy night time activities. Pairing what it does with how long it lasts on an Eneloop makes it the most valuable flashlight in my collection.
I got a few of the original run. When the colored ones came out, I ordered a bunch only to have them lost in the mail. Unfortunately, it was too late by the time I found out. I had missed my opportunity to stock up. 
If the new 3400K version is close to how good the original Yuji version was, I’ll buy a few. Getting them with a green body would be incredible. Green is my favorite body color when I can get it.
