【ツ】Wurkkos WK01/WK02 Sales Thread (US/DE codes available again)

yeah simliar like SF02 and update with Constant current circuit and the touch feeling of the tail cap as well as a bit more output :crown:

Not a real issue at all but just a minor, cosmetical imperfection: The CNC machining or post processing of the head units might deserve a closer look as I found some small nicks on my two samples, see pictures below. Again, nothing serious at all as this can also be found on Sofirn’s C01(S/R) lights, too. Moreover, the clip is slightly warped to one side, not being exactly in parallel to the tube - again, just a cosmetical imperfection for those being too nitpicking as me. After all, it will have no impact on the functionality of these nice lights. :slight_smile: Apart from this, both lights are well designed and assembled.

Thank you Lux-Perpetua sharing so many nice photos and details.

we found this minor cosmetical imperfection too , and talked to the factory they said it is difficult to avoid, maybe many people will have such complaints, I am thinking about how to help avoid this problem in the next batch,

The groupbuy is now active for European customers who want to order from Amazon DE, see updated OP.

The stock in Amazon's warehouses in Japan and the United States is yet to be released. I will update new codes as soon as stock becomes available.

Can the pill be taken out for en emitter swap?

The groupbuy is now active for AliExpress and Amazon JP, too.

According to Wurkkos the head is not glued, so it should be possible to dismantle the light.

WK01 looks nice

Absolutely. The new brown color looks very appealing. WK01 is a great alternative or addition to Sofirn's C01S. Using a constant current circuit was a very wise decision, too. Definitely a keeper, IMHO! :-)

Thanks! Looking forward to WK01 4000K in brown. :slight_smile:

WK01 is now available on Amazon.com, see OP.

WK02 is now also available on Amazon.com, see OP.

Ordered WK02, hope the switch is better than the a02.

Update:

New codes for WK01 / WK02 on Amazon US and Amazon DE.

Wurkkos WK01 SST20 4000K AAA forward clicky with Low, Medium and High modes.

WK01 SST20 4000K arrived today! I ordered it from the Sofirn Official store on AE.

I like the WK01 more than my i3T because of the 4000K tint and smaller size.

Are the drivers for WK01 and WK02 different?

Gonna say yes drivers are different,
Got the WK01 and tried to put the head on a Sofirn PF04, Thorfire PF04 and will not work, head is shorter, threads different depth.
I know people will say “just make a contact ring” but that would not be a good idea as I did put a LifePo 10440 in the WK01 and the modes just do not change and it really did not get much brighter so higher voltage is probably going to kill the driver with no gain, no upside.

Flashlight really works well at the recommended voltage though and the tint is awesome!
Could probably get away with primary lithium AAA which is usually around 1.75-1.80 volts and may see some increase in output.

Do wish it had mode memory, always starts on moon. Sometimes I need it to start on high like in daylight use under car hood etc.

Thanks! This gave me the courage to try an INR10440 at 4.2V in the WK01.

I found it difficult to get it to switch mode from Low to Medium and High while using a 10440. It looked like it was stuck on Medium.

I had to rapidly momentarily press the button forward to change from Low to Medium and High and then click it in. If I tried to slowly click between modes it remained in Low.

The beam looks nice on high with a 10440. It seems slightly brighter than an i3T on High with a 10440.

10440 Low is like AAA Medium
10440 Medium looks 30% brighter than AAA High
10440 High is looks 30% brighter than 10440 Medium

Wurkkos WK01 SST20 4000K vs Olight i3T

If you run it on High with a regular AAA for a minute, that’s about how hot it gets when running it on High with a 10440 after a few seconds. I wouldn’t recommend using a 10440. Something might burn out…


Would the 3V2 indicate that it supports 3.2V and that the WK01 and WK02 may be using the same driver? :sunglasses:

@Wurkkos: Thanks for not using red loctite! It’s much easier to play around with the flashlight.

Interested

Update:

New promo codes for Amazon US, see updated OP.

Just in case, should you have problems with the codes:

Sometimes it needs some hours before the actual promotion becomes active. So, please try again a bit later if it's not working already. ;-)
