[Review] Wurkkos WK30 - White/UV/Red 26650 Flashlight

Disclaimer: I was kindly offered the Wurkkos WK30 flashlight for review. Amazon link (non-aff)


General Info:
The Wurkkos WK30 is a new White / Red / UV flashlight, powered by a 26650 (or 18650 or 21700) battery. It is micro-USB rechargeable and comes with a 5000mAh Wurkkos-branded 26650 battery, among other things. The Sofirn 4000mAh 21700 that I tried did fit, but was definitely snug length-wise. The white LED is a Samsung LH351D 90-CRI 5000K, one of my current favorite LEDs: good lumen output, no obvious tint-shift, my fav CCT, etc. The red LED is a Cree XP-E2 (the product info says XP-E, but it looks like an XP-E2 to me). The UV LED is said to be made by LG, but no model numbers or specs are given for it.


Fit & Finish:
The quality of the WK30 is great. The anodizing is has a nice, satin feel to it. It has a good solid heft to it. The threads are relatively square and smooth, if slightly thin. The bezel appears to be glued on, at least I was having difficulty removing it by hand. The switch retaining ring is a nice blue color which adds a small pop of color. The USB cover seems thick and well secured.


Runtime:
A nice, flat regulated runtime. The light ran at 12 lumens for a long time before eventually shutting off with a measured battery voltage at 2.75V. Between the mass of the light and the timed stepdown, the light doesn’t really get too hot; it seemed to max out around 50°C. There’s also “Advanced Temperature Regulation” at 50°C in addition to the 3 minute timed stepdown. I really wish they wouldn’t do this. If you have ATR, you really don’t need a timed stepdown.



Operation:
The flashlight is operated entirely from a single side-mounted e-switch that has battery indicating LEDs under the switch cover. I could write out a UI description in my own words, but I’d really just be interpreting the already-clear instructions that Wurkkos provides, so I’ll just paste those here. What I will say is that I normally don’t like long-press for off. But in the WK30, it’s a pretty short “long press” and really not annoying. Much better than some other lights (looking at you, Wuben E05). Also, I was concerned that the UI would be overly complex or confusing by having 3 different colors at multiple levels each. While the UI is different than other lights, it’s actually pretty easy to use. So here it is:

In the state of power off…

  • Single Click: enter white light memory level, click to cycle through Eco-Low-Med-High lighting modes, press about 1-2seconds to turn off.
  • Double click: turning into red light mode, click to cycle Low-Med-High lighting modes, press about 1-2 seconds to turn off.
  • Triple click: turning into UV light mode, click to cycle Low-Med modes, long press to turn off; double click to enter white light memory mode.
  • Quadra click: lock out all function, click four times able release lock mode.
  • Long press:enter white light Eco mode, click to cycle Eco-Low-Med-High lighting modes.
  • Notice: Double click continuously to enter strobe modes, single click to cycle strobe-SOS-beacon, then double click back to normal modes when on strobe mode.(Only on White/Red memory level)




Misc Info:
This came packaged in a relatively nice cardboard box, and contained everything you’d need to run it: the flashlight, a Wurkkos-branded 5000mAh 26650 battery, a USB cable, spare o-rings, lanyard, battery spacer, and instructions. Overall, a nice kit for the asking price ($37 or so as of the time of this writing).


Here’s the WK30 with a few other well-known lights. Left to right: Convoy S2+, Wurkkos WK30, Sofirn SD05, and Emisar D1S

Coupon time! Wurkkos has kindly offered a 20% off code for my fellow BLF-ers: ILD2EECH.

Note, the code is supposed to take effect at 1pm on Sept 4th (not sure what time zone). I’m guessing it’s for Amazon US.

Hi gchart, thanks for the nice review.  Thumbs Up

I fully share your positive impressions. Smile

 

Some comments:

There's a new updated manual I have made for Wurkkos that you can easily download from ► here ◄.

The updated manual also includes the correct product/bin codes about the XP-E2 red (630nm), LH351D 5.000K 90CRI and LG LEUVA33U70UL00 (395nm).

On TLF someone tested to max out the WK30's thermal dissipation by restarting it once every 3 minutes. It seems there was no ATR in place in that sample. After 30 minutes is was heated up to 80°C.

Source: https://www.taschenlampen-forum.de/threads/wurkkos-wk30-lampe-mit-3-unterschiedlichen-leds.70998/page-3#post-1011570

I will ask Wurkkos if they did implement a thermal regulation in all WK30 lights or if there's just the 3min timer.

Great, thanks for the updated manual and the ATR link (and translation/summary)!

Just wanted to share with you some experience with my WK30.

I called this one “WK30: My Way”. It’s supposed to serve me in autumn and spring, when in the evening walks I need to use some light. It’s not that bright as winter ones, and not as light as summer ones.
I’ve swapped emitters, each has a role now Party
- XP-L HI V4 3C (from Hank’s Intl-Outdoor) – is supposed to throw farthest this host is capable of (White Flat was not possible due to 3535 footprint)
- Nichia 219B sw35 R9080 (thanks again Azhu) – is supposed to give most pleasant light
- XP-E2 620nm red – is supposed to preserve night vision and keep me away from buzzing insects

Playing with this flashlight consolidated my feeling: I do like multi-colors flashlight, especially modable.

My mod was limited to emitter swap although this wasn’t easiest mod I’ve done. The bezel is glued (with blue grade glue) so it took me a few minutes more. [edit: first I heated up the bezel to around 70 Celsius, then I used 2 strap wrenches to open it. Very slowly but finally the threads got loose.] The rest is easy if you clean up the threads well.

Original setup:

Awesome mod! Did you use strap wrenches to break the glue? Just get it hot and twist hard with your hands?

Thank you. Right, I should have mentioned it, did ‘edit’ in post.
Yes, heating up and two strap wrenches did the job.
