[review] Wurkkos WK20 diving light [and for the WK20S as well]

Yeah, I heard back that the new version is up for sale, 5300K!

Definitely not Angry Blue™!

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?

Yep

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

Good tint for a dive torch

Anyone have the 2000lm version yet? That in 5300K sounds pretty awesome. :laughing:

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

So now ya have it! :laughing:

:+1:

I feel like I just BINGO’d! Looking today for just such a light… between 3000 and 4000 kelvin, side switch, decent output. Order placed!

Yeh, you’re gonna love it. Nice and solid, seems bulletproof. And that WW light is reeeeeeeeally nice!

I was able to get both for review. Nice lights. I like the WK20 better just because of the tint. I’m going to order a 3000K XHP35-HD ftom arrow.com to put in the WK20S. But if you like the 5300K the WK20s is a good light also. It is sugnificantly brighter in the same size package.

That flashlight looks almost exactly like the Sofirn SD02A (uses XPL-HD 3000K tint)…

Any chance of a runtime test for this one?

Sofirn has an XHP35 version as well, with a different body design that isn’t dive level submersible. LINK. A good bit cheaper at $24.

Btw, it seems interest in that Wurkkos WK20S model caused price to spike from $39.95 to $49.95.

This is an interesting diving light: 10W-XM-L2-Diving-Flashlight. Very prominent carry-handle. It’s XM-L2, putting out 960lm, but has a proprietary battery pack serving 5400mAh with water tight charging port. LED indicator for battery level.

Yeh, I mentioned that up-top. Seems to be all-in-the-family. :laughing:

The Wurkkos arrived in today’s mail. It looks and feels good. The switch action feels really interesting. The beam certainly is more warm, sort of orange-yellow, than my yellowy Eagtac GX25A3 (3700K). But actually not quite as warm as the Adventure Sport Super Bulb XM-L2 S6 dropin in my 4D Maglite, even though the latter is supposed to be 3000K also. I look forward to seeing it at night.

First thing I noticed, though, was that the tailcap ridges aren’t pronounced enough to satisfy me; the light could still roll off a flat surface if bumped. Happily a Streamlight 75701 anti-roll ring fits and is now adorning the business end like a king’s crown.

The Streamlight Siege I’d been waiting for came in the same mail batch today, too. This is shaping up to be a great weekend! :partying_face:

Hey! The 2000lm NW ’20S is on sale for 34bux, and the 1000lm WW ’20 is reduced to 26bux.

I like the brightness of the ’20S, but the WW goodness of the ’20 can’t be beat.

And I added a write-up for the WK20S in the OP as well. See above.

Wanted to get some comparative beamshots (’20/’20S) against some trees but the neighbor’s got his spotlights on all night for the past two weeks, muddying up everything.

I’ve found that my muscle memory expects a light to turn off with a brief click, but since this light only advances the output mode by that means (off is via long press), it’s mildly irritating. Otherwise I like it. It tailstands more steadily than I thought it would just from looking at it.

Considering all the lights I have that need a click, press’n’hold, double-click, half-click, long-click, etc., it’s no big deal for me to adjust. Each one has its own “personality”.

Thank you, Lightbringer! You’re the best scout we have for interesting new lights that otherwise might be off the radar. The Wurkkos WK30 and WK20 are both terrific little lights. The WK20 is notable especially for the 3000K CCT, the nice 1 lumen low-low level, and the magnetic switch (which is much less vulnerable to grit than, for example, the ring on the Sofirn SD05).

I have mixed feelings about the WK20S. For underwater, I like the higher output. But, for out of the water use, it’s unfortunate Wurkkos eliminated the low-low level. And then there is the tint. Back in post #8, Lightbringer, you worried about the potential “urine-yellow corona” of the XP35. Well, that’s what my copy has. Reading the description too quickly, I thought the emitter was an XHP35 HI, but it is actually the XHP35 HD, which is notorius for its tint shift: in my case, a neutral white hot spot, yellow corona, and purplish spill. Is yours better? Diffusion film could probably help, but I don’t want to lose any throw.

I plan to use both the WK20 and WK20S on a freediving trip to Catalina Island in September, and I will report back on how the lights performed underwater, and whether the tint problems of the WK20S were noticeable in actual use.

:blush:

Absolutely. I reviewed one ’20 and bought another ’20 just because of the CT/tint and it being a great little light.

I didn’t even think about the grit factor, though. If I knew how the rings came off the ’20 and ’05, maybe I could figure out a way to prevent ingress (eg, slap on some waterproof grease to “pack” the gap).

Yeah, mine has that, too. A lot of flip-chips have that problem (and some non-flip-chips, too). I imagine that underwater and backscattering, it’d be less of a problem (built-in diffusion film, so to speak). When white-wall hunting, yeah, it’s very noticeable.

It’s funny you mention diffusion film, though. I slapped a sticky piece (“frost”, I think) on the ’05 to get rid of the corona, and it’s an incredible — and I mean incredible — indoor floodlight. I love my Cometa for indoor lighting, like going down the basement and not bothering to flick on the lights, etc., and it’s a wonderfully even blanket of light… within the lit circle. A bit harsh as things come into and go out of view. But the ’20S with its hella bright beam and diffusion film, it’s a similar wall of light, but with much softer edges. Like an area light, hella bright, but not like a stage-light with harsh edges to the beam.

Even the WW ’20 looks incredible with DF on the front glass. Moonlight/Lowest is incredible for close-in viewing like just checking the clock or whatnot.

Kewl, sounds good! I’d think it wouldn’t be a problem, much less so in murkier water (again, acting as its own “diffusion film”), but that’s only a guess. I’m thinking you’ll be impressed, too. :laughing:

Oh, check out Markus’s review of the ’05, too.
