Thread: C2 Centurion

  1. #1

    Default C2 Centurion

    Greetings,

    Found a C2 Centurion in one of my old duffel bags. After a few searches Ive found my way here. I've already surmised that pretty much everything made for the C2 was discontinued years ago. Is this thing worth keeping, and if so, what tail caps/ bulbs can I use in it? Definitely not opposed to going LED.

    Cheers

    Congrats on the C2! One of my all time favorites. Google search "Surefire 6P upgrades", "P60 dropins", "Z41 McClicky kit" in the CPF search bar, above and right side below the header. You can spend $20 on up ton many hundreds of dollars making the C2 into pretty much anything you want. We're here to help! Enjoy the ride...

    Lumensfsctory still makes compatible bulbs if you want to stay incandescent, by the way.

    One of my greatest flashaholic regrets in life is selling my Centurion. Lots of cool ways to upgrade it. If it were mine, I'd get the 219b version of the Malkoff M61, still available from illumination supply. If high CRI is not your thing, then I'd go straight to Malkoff Devices and get the flavor of M61 you like most. These drop ins are essentially indestructible and will make the most of your flashlight.

    I literally just scored one on eBay for cheap. Very cheap. And in pretty good shape. Never had one before. Not even sure what I’m going to do with it but for the price it was a no brainer. Looks like a great light.

    Although I know that some here prefer the Z's, for my money, the C-series SureFires are best-of-the-best P60 hosts.

    +1 on the illumn.com special edition P60 drop-ins - the Malkoff 219b V3s. Unfortunately there’s only like 3 left, so if you want one, action it fast. I have two: a LL and a LLL. For a single mode light, the lower lumens is more all-around useful (for me).

    Judging by all the congrats I got on the find, I'm gonna assume it's very much worth keeping.

    Im gonna try to find a click on tail cap to replace the momentary/twist on it came with, and probably a nice LED and reflector with great throw.

    Looks like a lot of folks also have the body bored out to fit an 18650. Not sure I like that idea as it doesn't look like there would be much of a wall left.

    A 16650 rechargable cell will fit perfectly in a stock C2 without bore work and run all but the most high powered drop in modules. Runtime depends on power demands, but spare cells are easy to carry.

    Haha!! Sorry, kinda misquoted you there, but posts like this make me laugh. You got a gem there. I wish I could look into old dufflebags and find random classic Surefire lights.

    They look good quality. Seems they only offer cool white though. I see 5K listed as both "cool" and "neutral" on the same page of their site.

    I consider 4K to be where cool tint starts. Though most will refer to 4K as neutral.

    Someone say c2, lot of love here. One of my all time fav's for sure.


    Cryos bezels , OR triad tails,in no order many engine(and bulb) options....... sportac/malkoff/EDC+/Oveready/p60vn's/lumensfactory/tana off top of my head.
    McClicky tail cap is another option for the back end. Can run sanyo/keeppower 16650 fuel, so 2500mah and good for around 5a ish for easy guilt free lumens.

    Well, I ordered a Malkoff M61N drop in. Going to be ordering an M41 McClicky Med press tail cap next week. Any recommendations on 16650's? This will be my first jump into Lithium Ion rechargeables.

    Well, I only have one (XHP35) but that´s definitly warmer than my Oveready V5 4500k XP-L dropin.

    If you prefer a clicky, then you'll find multiple options. However, many people, including me, think that the momentary/twist tail cap from Surefire is the finest mechanical flashlight switch ever built. They last forever, whereas clicky things wear out and are more prone to failure. Just something to consider.

    +1 on the 16650. No need to have the battery tube bored out.

    Any reputable seller with Sanyo based 16650 cells are good to go. Anything from ebay or with "fire" in the name may be more trouble than they're worth. The cost difference is neglegible, may as well run quality batteries.

    Battery Junction is way more reliable than eBay or Amazon who often times do not know a supplier sells fakes.

    The thing I learned at vaper sites was to watch out for "re-wraps" which are not necessarily bad batteries but mostly indicate over inflated numbers.

    It's very difficult to start this crazy hobby with a better platform than a SureFire C2 - a very fine light in its own right, and the upgrade options are nearly endless.

    You have also made an exceedingly fine purchase with that Malkoff M61N.
    A single 16650 LiIon will run that module very well (i.e. not getting the light bored for an 18650, for the time being).

    If you ever do go into the very high-output dropins (e.g 1000+ lumen triples), that would be a good point to consider getting the body 18mm bored.

    Until then, enjoy your light - a SF C2 with a Malkoff "N" is one of the very finest illumination tools ever assembled.

    How close of attention do those of you who run 18650's and the like, to the battery voltage for recharging? Started doing research on Li-ion cells and I'm not sure I want to go down that rabbit hole if I need to monitor voltages that much/often. Can I get away with a quality charger from Nitecore and just recharge when the light dies? I see many newer lights have built in charge indicators but the old C2 doesnt.

    For the M61N you have on order, a protected 16650 puts out plenty of amperage to run the module. The protection circuit won't let the battery over discharge, and any decent charger won't over charge your cell. I'd charge my 16650, turn on a light and a stopwatch at the same time, and run it until it shuts down so you have a good idea of total runtime you can expect on a charged cell.

    16650 ordered, along with a Nitecore F2 charger.

    What mods have you all done to the C2?

    I hesitate to recommend mods without seeing a pic of your light first. If it's an old "crosshairs" logo, anything quasi-permanent may lower value. A McClicky tailcap kit for the original tailcap or a replacement with a clicky already in place, another common mod is a new bezel ring to protect your stock head. You'd most likely need a bezel wrench to remove the old one.

    +1 on pics needed first; my particular thing are the oldest "3-flats" C's - so few of them around compared to the revised "4-flats" models.
