[Info-Thread] Wurkkos FC11 - 18650 EDC, LH351D 5000K 90CRI, USB-C, magnetic tail

Hello everyone,

Wurkkos is about to release another interesting EDC flashlight. It's called "FC11" and has some nice unique selling propositions that I would like to bring closer to you. For instance, it comes with a USB-C port for convenient and flexible recharging. Moreover, it uses the popular and powerful Samsung LH351D LED in neutralwhite tint (5.000K CCT) and 90CRI for high color rendition. For more versatility Wurkkos also implemented a magnetic tailcap as well as two mode groups (stepped modes and ramping).

Production is ongoing now and sales are expected to start by 11/11 sales with multiple options, i.e. purchasing with or w/o battery from AliExpress and Amazon.

Prices are not committed yet but it is expected to be below $ 30.00 with battery included.

User Interface

Group 1: Stepped modes (default)

  • Fast click to turn on; press and hold for 0.5 second to turn off
  • Fast click the side switch to cycle through modes:
    Eco → Low → Mid → High → Eco → Low → etc.
  • Doubleclick to activate turbo mode, one click to return to the previous brightness setting.
  • Tripleclick to activate strobe mode, one click to return to stepped mode and previous brightness setting.

Toggle between Group 1 and Group 2

  • press & hold the switch for 3 seconds from OFF. Two blinks will confirm the mode group change.

Group 2: Ramping

  • Fast click to turn on or turn off
  • Ramping: Press and hold side switch to ramp up or down. Ramping changes direction by pressing the button again within 1.5 seconds; same direction when ramping again after 1.5 seconds.
  • The light flashes one time when it reaches floor or ceiling (both ends of the ramping range).
  • Doubleclick to activate ceiling level ("turbo"), one click leads back to the last brightness setting.
  • Tripleclick activates the strobe mode, one click leads back to ramping mode and last brightness setting.

Electronic Lockout (to avoid accidental activation e.g. in one's pocket or backpack)

  • 4 fast clicks to lock the flashlight, the light flashes twice for confirmation.
  • 4 fast clicks to unlock the flashlight. The FC11 will turn on in the previously used mode.

Indeed, it looks promising. Any pricing info?

This should be promising. It’s a great LED choice for sure.

Looks good, quite like the blue ring. Good emitter option, will be curious if the UI ticks the boxes.

OP updated ;-) I have no detailed prices yet but I will inform about it a.s.a.p..

I will supplement information on the UI later on.

I love my WK30 so I might have to pick one of these up. That emitter is amazing!

I would love to see Wurkos come out with a small (as small as possible) 18350 light with the LH351D emitter and smooth ramping. I’d be happy with a TIR optic to keep the size down but a reflector version would be cool too.

Looks like it might share some Sofirn genes. Specifically the SC31B.

It certainly shares one thing. The mediocre clip that is on hundreds of other lights :slight_smile:

In for one!

It looks like SC31B head with ED01/Worm ribbed body.

I hope they tweaked the UI to have faster ramping and a lower low. I never use it on the SP32 because Anduril/Narsil does it better.

Looks good. Waiting for more UI info

UI and ANSI specs supplemented.

Why designers choose “hold for off, click to cycle modes” instead of the reverse is… puzzling.

It’s like people without legs designed a bicycle for people without hands.

Technically it works, but it’s awkward and non-intuitive.

I think it might be to prevent returns from users used to lights having a single mode - not that it justifies it, just my theory.

I prefer clicking to change modes, unless in ramping mode - then I control how fast the modes change and always stop on the desired mode.

With hold to change modes, as on my Rofis R1 and R2, I sometimes have to go through the cycle a couple times to stop on the correct mode.

I do like click for off, but you can’t have click for off and click to change modes in the same single switch light.

Oh boy. I’m excited about this light.

Please tell me this is roughly the same reflector as the WK30.

I call that the “Acme Clip” :smiley:

I haven’t used any Rofis lights but no light with hold-for-cycle I’ve used has been anywhere close to fast enough to overshoot what I want. I do like how fast you can cycle them with rapid taps on tail-switch lights and the dual-switch TO50R I have though.

My thoughts…

The Good:

  • Great LED choice :+1:
  • USB-C charging? Awesome
  • Shortcut to turbo (will this work from Off?)
  • Ramping option with single click on/off
  • Below $30 including a battery :money_mouth_face:

The Bad:

  • No mention of Eco/moonlight shortcut (hold from Off would be good)
  • Hold-for-off in the stepped mode
  • Timed stepdown instead of temperature regulation: given the price point, I can forgive this. But it does make me a bit sad
