I like my pocket lights as small as I can get them. Have a quark mini mkiii on a p7 clip. Expensive for what it is, but got it on black Friday. Not many small twisty lights left, and this is the only one I found that came on high
Ive got two from 2003, never tried the led models. I love these lights, they feel great in the hand and the switch feels so much better then on my 6Ps. They also have the adjustable beam. They even look better aesthetically IMO. I dont know why they weren't as popular as the 6Ps.The M6 may be much easier to find and also cheaper, but the M1 is much more rare and difficult to source, hence the price hike. And if you're dying for the very original 3310 then well, good luck with that...
But even the M6 (2320 incan) has had different batches and if you've got a pre-2005 one, great -- the HAII black finishing holds a bit better than subsequent ones (2006 or later). My very first M6 (2320 NOS) is one such example.
That said, the M6 (2320) is gradually running out and the only other variant you can find easily is the 2330 LED model. Not sure if the build quality is as good as the incan original though, but it was released at the same time as the M1 (2310 LED) back in 2006 I believe.
It might be because a primary 3 volt is only pulling 2.2-2.4 volts under load. Thinking the keeppower might be and actually 3 volts. Just a guessWe talked about the Keeppower 3V rcr123a here before. I tried to pair a lumens fractory HO-E1A with one yesterday evening. It blew the bulb immediately. So much for it being a "direct replacement for cr123s". I did not expect that, especially since I had no problems with them in my 6Ps or peli M6. Just a warning to anyone who might want to try that.
You might be interested in trying the Tactician head on a Malkoff MDC body using rechargeables… it is an awesome setup. The Maxvision beam is, from my perspective, superb and with Efest flattop 16430’s, IIRC, I get >300 lumens for 45 minutes. Low works great also when needed.I have used/carried all the below CR123A lights as EDC. Listed in order of purchase as I only started using CR123A lights since 2015.
Streamlight Protac 1L (180 lumens). 2015.
Stopped using as developed terrible flicker after a about 18 months, that I couldn't resolve (tried everything including other switches), so issue seems to be in the head, but never dropped.
Elzetta Alpha. 2016.
Stopped using as high only, so of limited use. Plan to sell.
Streamlight Protac 1L-1AA. 2016
Now my backup light, carried on my EDC pack. I don't really trust the Streamlight Protac series as they are cheap Chinese made lights and I have had bad flicker issues with 3 other models, but so far this one has held up good.
HDS EDC Executive 250. 2018.
Most most used/carried. Best EDC light ever IMO, I highly recommended it. Long runtimes, perfect balance of beam, and good throw on the XP-G2. I've never felt I needed more than it's 250 lumens.
Malkoff MDC SHO. 2018.
Recently sold as I just wasn't using it any more, due to high only.
HDS EDC LE 250. 2019.
Second most used/carried. Awesome runtime on high, but hard to beat the general utility of the Executive model.
Surefire Backup E1B-MV. 2019.
Nice light, but stopped carrying as it has a terrible 27 min runtime on a primary CR123. Nice low for indoors, but of limited use walking outside in the urban areas. Still deciding to sell or not.
Surefire Vampire V1. 2020.
Nice throw, but of limited applications after I carried it for a while. Also plan to sell.
Although there are so many CR123 lights on the market, many have side power buttons (Olight etc), I avoid all these types, so only ever considered the above for EDC pocket carry.
Overall I've been fairly disappointed with most of my CR123 lights, apart from my HDS ones. If HDS Systems didn't exist I'd probably go back to AA lights and carry a Fenix E12 V2.0.
