[review] Wurkkos WK20 diving light

[CCed from my Amazon review]

Really nice warm-white diving light!

Admittedly, I don’t dive, and am not likely to do so, but I do like the “waterproofness” of diving lights (like my Ultrafire DV-S9s) to be able to use them in any kind of weather without concern. So when I saw the WK20 listed, and in warm white yet, I had to try one. And then another. Big Smile

When I got it, I was pleasantly surprised. Even the box it came in was quite nice. Inside, the light was packed along with the manual, lanyard, charger, cable, and the included 18650 cell inside the light itself.

First impression was that this was a solid light, built like a tank! Nice heft, perfect semi-gloss black ano, a wonderfully springy magnetic side-switch… it just felt good to hold.

Didn’t even wait to charge the cell, just removed the insulating disc and fired it up. Nice incandescent-like warm-white light! It’s been ages since I’ve seen a light offered with a WW emitter, my last being a Sofirn SP36WW. And speaking of Sofirn, this light could be a clone of the Sofirn SD02 diving light (which I believe is neutral-white and not warm-white). So right there is a great sign that this’ll be a great light.

Externally, again, flawless semi-gloss ano, no chips or dings anywhere. Aside from the tailcap, I couldn’t disassemble the light further, so it might be glued shut to also help keep out water. A bit disappointing, as I like looking at the innards.

The UI is simplicity itself. Click on, click to advance modes, click’n‘hold to turn off. Low-to-high, with memory. 5 modes, very nicely spaced. I thought I was at the brightest at #4 and gave one more click to go back down to low, but it got even brighter! LOL Nice!

The lanyard is a nice thick “rope” type with the little slider thingy attached.

The beam is pretty clean, nice round central hotspot, faint corona, slightly less-warm spill, but not fried-eggy in any way.

I did a quick dunk test for a while in a utility sink, and there was no indication of any water ingress, no condensation afterward, nothing. True, it’s not diving 100’ underwater or anything, but it’s something.

And the warm-white light itself is quite nice. Longer wavelengths (reds, yellows) tend to penetrate fog, mist, haze, etc., much better than shorter wavelengths (blue, violet), so I wondered why diving lights were almost always cool-white, which would just reflect right back in your face unless the water would be crystal clear. At least warm-white would penetrate farther in murky water. So even if I don’t dive, the WK20 would be the perfect light to use in fog, mist, haze, rain, etc., not just because it’s waterproof, but for better “reach” than a cool-white light.

And outside, especially with greenery around, reds and browns just pop under warm-white light, whereas they’d be washed out to faded dark-pink and gray-brown under cool-white light. Quite nice!

Basically, I can’t find anything about the light to even nitpick about. (Okay, maybe the glue, as I want to see the insides, but… Innocent )

Definitely recommended, even if you have no intention to go diving.

Incidentally, once I get pix on Amazon and can link them here, I will.

Just did! “Thumbnail” pix are clickable for bigger images.

Think it is an XPL2. Correct me if I am wrong Lightbringer.

specs say XP-L 3000K. I think it’s cooler than that, more like 3500K. Absolutely love mine! This is one quality offering, tank like in its build! And has one of the greatest feeling switches of any of my 100 + lights. Comes with a good cell and charger …. no brainer!

Hmm, I’ll have to compare for sure once I get home, but just from memory, I think it was an L2.

But yeah to all of the above. Really nicely put together, great switch-feel, nice beam, everything. That’s why I got 2 of ‘em. LOL

I’m interested in the WK20S with an XHP35 HD in it. Twice the output as well. I bet it will be great. For what it is intended for anyway.

I think that’s coming next, no?

My only “fear” is that if the ’35 is a quad G3, then it’d likely have the same hideous urine-yellow corona that most G3s have. I’m hoping not, though. Diffusion film would likely fix that, but at the expense of throw.

But yeah, twice the lemons would definitely be nice!

I see there’s two options on lumens: 1,000 and 2,000. Did you get both?

Ummm, nope? I got the WW 1000lm version.

Think the new one’s 2000lm and NW/CW. Not sure if it’s out yet.

They are showing two purchase options, the 1000lm for $29.95 and 2000lm for $39.95.

Did you communicate directly with the seller dingnuo? The 1000lm version lists 3000k, but when selecting 2000lm there is no temperature listed. Is it 5300k?

I thought it said so… somewhere. Can’t recall where.

Ummm, in all the rush, I don’t think I included a link to the light itself on Amazon:

https://www.amazon.com/Diving-Waterproof-Flashlight-Underwater-Battery/d...

So now ya have it! LOL
