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
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.
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
