I get so disappointed when Markus doesn’t blow up a light…
That said, proprietary is okay IF you can still use a regular cell. Eg, some lights will only have both poles brought to the front to be able to charge it in situ vs having to remove the cell to charge externally (or do things the old way and have to turn the light on in order to charge it).
And I love the old WK30. I thought it was a “gimmick” light at first, but when I played with it a while, man, it’s a hoot!
Infuriating. I don’t know why Olight thinks that THEY can get away with this. SONY tried it with Betamax and their proprietary memory sticks. Apple tried it with MacOS and had to eventually make iOS actually Linux under the covers. Proprietary replaceable batteries are kind of a death sentence, unless the maker offers them more cheaply and with promised abundance. Olight charges MORE for the same equivalent cell type and mAh than you can get with other 3rd parties. No, batteries are all about standardizing… and if you select an under-spec battery you simply get under-spec performance (e.g. 20A vs. 2A).
Olight makes some great hosts. I like their mostly simplistic, predictable UI’s. You grab an Olight and most of the time the clicks and click+hold commands are homogeneous. In their arrogance, Wurkkos will eat their lunch… or at least the more delectable side dishes not as costly as the entree. 
:partying_face:
I’ll accept a proprietary battery if it’s a built-in one and there IS a path to DIY replacement if so inclined. Olight does make good batteries, but $/mAh ratio is not very good.
I did flamethrower it and I took it for a warm shower. That has to be enough for a start. Within a few weeks it will have hit the ground many times but maybe I will still strap some explosives to it just to make sure
Sooo….it is a gimmick? You said it was a hoot not that it was useful! 
When recharging, the FC12 doesn’t require the tail switch to be clicked on. Does this mean it’s not truly mechanical and does not provide a physical lockout? Not necessarily a major concern for a duty light but something to be aware of.
I’d also rather use non proprietary batteries, but given the flashlight “has” what I want, it is a risk I’m willing to take in that model.
Klarus is doing the same thing regarding their similar model (E1).
From the manufacturer standpoint, they are creating and feeding a niche [good for them…] while for us customers it is another PITA, not having easily available cheap batteries that can be used in that/those flashlight(s). And we know that most manufacturers care about the customers’…money!
I also agree that their non-proprietary batteries are overpriced and we can easily find other substitutes. Only a true fan/fool would buy them. Maybe like Nitecore batteries too.
We can only hope that the market doesn’t become flooded with lights w/ proprietary batteries. But if they have what I need/want, I may risk it…
Sorry Markus for derailing the thread :person_facepalming:
BTW, Markus, can the FC12 be charged with any regilar USB-C cable or only the included one? TraiTrek had some complaints regarding the SC21 only taking the included cable, so I wanted to know, too! Thanks again!
When I screw off the tailcap and create a contact between tube and negative terminal the light comes on as I would expect from a mechanical switch system. It seems to charge no matter what position the mechanical switch is in. I have to check. Interesting.
Not a derailing as it was a big part in my original review. I am feed up with the proprietary battery system but I see the advantage in a professional user context. For emergency prep, survival, general use it is a nightmare though.
I am charging the light right now with a generic USB-C cable and it works fine, did not even unpack the original one yet. I have used a few different cabels on it so far. No problems unless perhaps u use a very fat one
Naw, it’s really handy. Normal creamy-white light, handy-dandy red to not get et by bugs when going outside, UV to make opossums fluoresce red.
It is hard to overstate how awesome the WK30 is: The primary light is creamy neutral white perfect for close-up and midrange. Floody, good color rendition. Perfect to explore stuff and take pics, make a movie. The UV (now 365NM!) and redlight are very powerful and with a good, floody beam each. All of that is powered from a 26650 cell giving long runtimes. All of it in a very compact and super robust package. And there is a red/white strobe for the child in each of us with the UI as perfect as it gets with a single electronic switch.
The WK30 has a slot in my EDC-backpack and it will go with me everywhere there might be something to discover. The best light for the money, more or less a true must-have.
Thanks for your feedback on that
Perhaps the smaller body of the SC21 has less space for different (fatter/larger) cables. My RovyVon A23 doesn’t take all cables as well, and also other lights with micro USB, so I asked for that and it’s good that it can be charged by different ones
Yep. I was able to fully charge a battery in the FC12 with the tail switch in the off position. There’s a PCB visible below the tail spring so clearly not a simple mechanical switch.
Edit: Using an amazon cable, not the included cable. Works fine.
Here is my 3D printed tactical ring for the FC 12:
The ring is designed so you first pull it into the clip and then move it over the battery tube. Screw on the tailcap. If someone would like the stl-file I can share it.
UV makes opossums glow? Very interesting! Is it as creepy-looking as it sounds?
I guess I’ve hesitated to get a UV light because I’m worried I’d somehow inadvertently make my crummy vision even worse. Also, why does this model have no knurling? It looks like a diving light and I’m not a big fan of that look.
Thanks for review. I ordered one. And not be the last.
The white parts of their fur glow pinkish-red, yeh. Got it on video, too.
The WK30? It’s hourglass-shaped, so you ain’t gonna be losing it anytime soon if you grab it around the middle.
I like it. It’s not too “busy”.
You kann still wrap it or ask your grandma to knit something nice for the WK30 :confounded:
UPDATE Here are a few pics showing how my FC12 looks like after many drops to the hard floor and more than a dozen shifts. It has run now for many hours, mostly on medium settings. I also had to use it as searchlight on runaway folks. The range of the light made a difference in the effort. 100% reliable and pleasant to work: It just works, a great tool. BTW: It greatly benefits from the tactical ring at least the way I use it. To my surprise the PLA (+) print does not even break

Yes, many different colors. And it holds up great. I don’t know if it is a PLA+ variation of PLA but it really does well.
