Yep, there it is... looking at mine. I can't believe I missed that! I must have been blinded by the (UV) light!
The inside of the tailcap is also the same exact design as the SP33. Another mm in diameter and they’d probably be interchangeable.
Talked to the Aliexpress seller for the WK30 and asked them about other colors and they said " Yes, Wurkkos are considering now doing a four color mix flashlight, with ,red, green, blue and white".
I was pleasantly surprised by the quality of this light. Once you get the ui down you are good to go. I really like mine.
Me too, it's a solid little light and really well finished. Not sure why, but I find myself playing more with this light than any of my other lights, it's just a fun light. When they make the 4 colored light, I'll order several as Christmas gifts since it takes protected cells.
Good God, even skipping through that in 10-15sec jumps, I had to stop at the 5min mark ’cause I felt myself slipping into a coma. Talk about a cure for insomnia…
“Hmm, here’s an instruction manual… looks like it’s printed on paper… these look like words… hmmm, some look like English, some like other languages…” Blah, blah, blah. Thank you, Captain Obvious. snnxxxxxxx…
Lightbringer!! Honestly, your posts crack me up sometimes. 
LOL!
I have seen this guy’s reviews before, and yeah he’s no Advanced Knife Bro…
But I gotta say, he’s fairly thorough and does include beamshots.
Don’t be an a-hole
I wonder if there's any light in Charles' world that is not amazing, outstanding, wonderful, marvellous or simply just great. If praising everything to heaven in 5min and waving a flashlight from left to right over someone's lawn is the ideal way to get expensive lights for free or even get paid for doing reviews, I'm afraid most of us on BLF seem to do something wrong. :-D
As I’ve said, if you start giving bad reviews you don’t get lights to review. Too many guys do inside beam shots, or none at all. And whoever wants a review doesn’t send trash. I, for one, like the ‘tree of life’ 
lol what? i dont understand a word u sayin lightbringer
I didn’t even get that far. I was dreading the “Well, it seems you push this button and it lights up…” part.
5min? I might be able to sit through that, but this was like 20min worth of nothing.
Seriously, when I heard, “Let’s open the box and see what’s inside…”, I was tempted to quit right there.
You ain't seen nothin' yet! ^:) :D
At least, he's quite consistent with all of his reviews on YT.
All reviews begin with: "Alright, let's see what's inside..."
All reviews end with something like: "This is a terrific flashlight [please fill in any manufacturer] has made. Great quality. I'm really impressed. Check for my discount code below..."
I must confess, I start to like his reviews. If I ever get the feeling, something's missing about the accessories of one of my flashlights, it's quicker to check his review than looking anywhere on BLF. ;-)
Kind of makes you want to mail him a Glitter Bomb with a Flashlight label on it, right?
“Let’s open the box and see what’s inside…”
>FOOM!<
