[review] Wurkkos WK30 white/red/UV light

Thanks for the readings - very useful.

OK, now I’m shopping for changes. Bought XP-G2 and Seoul Viosys UV 365nm Z5.
My plan is to:

- switch white to LH351D 4000K (yet from L4P) <— meant for close range

- switch red to XP-G2 de-domed / sliced <— meant for long range

  • switch UV 390 to Seoul Viosys <— meant for… ummm… nothing?

I wish all the modes had more amperage, but that seems way beyond my capability. Anyway, would you advice any changes? Is Seol UV good choice? Considering rather low power: is there any commonly available LED that could throw further with this Amps?

FYI

Please find updated manuals in English and German language here:

Could not resist. Swapped leds: White to 219C 5700K, Red to SST-20 2700K.

Measured (lumens):
219C (5700K) - 5, 120, 402, 901
SST-20 (2700K) - 1, 115, 326

White LED lost some output but I need the high CRI 5700K for work more than the stock 5000K LH351D although those are actually nice for general usage. The tint of the 219C 5700K (from jaxman) is quite nice and even a little bit rosier than the 5000+6500K e21A mix that I have. Will replace UV with 365nm but I only have Nichias at the moment and those, I realized, use different pads.

:laughing:

And I’m going crazy just trying to find a decent (molle) holster for it.

Got some Jetbeam holsters that fit tubelights perfectly, but it’s quite snug trying to stuff a ’30 into it.

Ordered some Convoy C8 holsters, just got ’em, perfect width but the flap is looooooooooooong. Yeah, scratch that, they’re going to hold actual C8s instead.

Saw some “universal”(?) holsters at FT which are adjustable out the wazoo that are a good 2’ wide, so those might work.

Any suggestions, let’s hear ’em. :slight_smile:

I got a Convoy holster that fits it perfect. Hhhmmm, not the biggest Convoy holster - not sure of size though.

Just measured mine - it's 45 mm across, from edge to edge, maybe 50 mm including the 18650 holder. Open up, its about 22.7 cm long. Closed it's about 130 mm with the Velcro aligned. With the WK30 in it, you only get about 1/3 down the Velcro, so the light is a little too long but still fastens well. Width wise it's good.

So I guess it's not perfect - I'm guessing it's the S2+/S3 holster but the spec'd dims look weird. Dunno why it's so hard to get simple well defined specs on these things...

Mmm, I may have to try a coupla those universal holsters…

“NaitHawk”? Who named it that? Tommy Wiseau?

Thanks for the recommendation Lightbringer! I just ordered mine for $29.99 with that coupon code! It’ll be here on Thursday and I’ll test it out on my Tarantula.

Kewl, enjoy!

WK30

Good ease for many.
Do you send all pieces directly from China?

I like this light so much that I’m considering purchase of another one. It’s like having 3 flashlights in one.

If you ever want to make my dream come true, please release BLF version with each of 3 leds powered at least 3A.

This would be nice. Maybe an LT1 style driver with tint mixing for the 2 leds and a separate channel for the UV.

This is exactly what I was thinking when I was reading the specs. :+1:

I would appreciate an advanced WK30S with following features:

✔ Cree XP-E2 deep red (660nm) instead of XP-E2 red (630nm) to better maintain nightvision capability

✔ LG LEUVA33W70RL00 365nm UV LED instead of LG LEUVA33U70UL00 395nm for more output and more effective UV spectrum (maybe incl. ZWB2 filter)

✔ USB port moved into the thread section between head and battery tube for better ingress protection and less wear & tear with rubber boot and microUSB port

✔ USB-C port with QC 2.0 (18W) charging circuit

✔ knurling on tailcap (and battery tube) for better tactile handling

I think this may increase costs by less than $ 10.

I agree with all the above - great updates. I would like to see some improvements in the UI as well:

  • I'd like to see white and red treated equally - last used of white or red is the default for 1 click ON. You can debate about UV, maybe it should also be capable of defaulting.
  • of course I'd like to see smooth ramping, but if not, then do course mode level ramping, like in Anduril, press&hold to ramp, 1 click for OFF
  • 1 click to last used level, press&hold to lowest, maybe keep dbl click and triple click for navigating to the next LED outputs
  • the timing of the current dbl and triple click is a bit rough. I often find I'm not quick enough - I think the tolerances are too tight.

You lose dbl click to max, but max could still be the last used level. Also this keeps it all pretty simple, hopefully easy to understand by most.

Of course for the driver, a triple channel driver like what TA has designed could work, but wire each channel's output separately - the FET for the white, a large 7135 bank for the red, and a small 7135 bank for the UV - it's about a perfect match up. If you have room for a 22 mm driver, which it should, then it should be do-able. This would be a great foundation for BLF modding - add more 7135's for more power, better firmware options, spring bypasses, etc.

I've made cuts and jumpers for converting triple channel BLF drivers to multiple LED outputs (2), and modified NarsilM to work with them - worked out well for my Lumintop EDC Mini II with the side flood LED.

This flashlight is so awesome!! It’s so much fun. I wish I would have bought it when I first saw it, but I thought it was a gimmick flashlight. But it’s not.

Yep, Glad I got in on one. I’m waiting on the upgrade…I hope:exclamation: to get a 2nd.

Nice, thanks a lot for posting this important detail!

Hahaha.. the red light bring your house more interesting

I like all the Version 2 ideas above and would like to add a very strong magnetic tailcap.

Thank you for the suggestions we will consider it seriously ,yes it will cost more if upgrade, so what is the range if for a budget light?
