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

Rough/sharp edges exist on all my Sofirn lights and I personally find it taints the experience. I know we’re talking budget lights, this is BLF after all, but I’d rather pay a little extra for nice chamfered edges.

Thank you for your feedback, i will test the bug of ui and feedback to the engineer to fix it

Lost the bin lottery I guess

Better slice it :wink:

I think I may just outright replace it. Even the CRI seems a few points less. I think they changed what they feed the dog

I sliced it after all:

Don’t know if (known) bug or error with instruction manual.

In both modes, continuing to hold button from OFF does not do the intended action and instead switches between modes.

Excerpt from manual below.

Stepped mode:
From OFF, hold 1 second to Eco, then keep holding to cycle through stepped modes.

Ramping mode:
From OFF, hold 1 second to Eco, then keep holding will adjust brightness steplessly.

You could try with the front lens off in case an AR coating is affecting it.

It’s a plain lens, no change.

thanks for posting your data captures (I summarized to show change in duv and R9):

still smells like a dogfart

From what I’ve found, the bug is only when the flashlight is in stepped mode. I don’t have this problem when in ramping.

Received the FC11 today. Battery is charging, so I am currently using a Samsung 35E protected button top to test out the light. Liking it a lot so far. The magnetic tail cap is pretty strong…

Here it is stuck to the Real Steel Flying Shark. I even moved the blade around a bit, but the FC11 held on.

So how’s the pwm for this light?

@Swabs:

Nice Firesticks!

(the succulent in your yard.)

Tendou - I don’t notice any PWM. I think the light is really good.

raccoon city - Thank you.

Thank you. I will get one then

This flashlight is pretty amazing for the price. I am very happy with it. But is there any special handling of the battery necessary?

This has been my EDC since I received it. It has a great (for me) UI, and a nice beam. Its easy to carry… it has never accidentally turned on in my pocket. The light is usable… good temp, no tint, high CRI. It has C-C charging that works. Its a really nice flashlight. My only wish is that the side switch was lit when the light is turned off.

Hi everyone! This is my first hi CRI flashlight and I really love it for a beautiful 4000k tint. I’ve got it also to have more sophisticated ui than standard commonly used ‘lo-med-hi’ in many cheap flashlights. I own it for like 4-5 months and have mainly positive emotions from usage.

However I’ve got some bugs that frustrating me a little:

1. Low voltage red light starts blinking at something like 3.9-3.8 Volts. It seems to me that this is clearly more than it should be. This problem occurs with any cell I have, even with standard Wurkkos 3000mAh 18650. This problem was from the very beginning and is not that awful.

2. Turned on flashlight sometimes won’t turn off untill you either change brightness or activate turbo or strobe. Especially if the flashlight was on for a longer than 5~10 minutes. This problem started to bother me about a month or so ago.

3. Memorized brightness level falls to eco after you turn flashlight in eco mode from off (with long press). Like if you turned off on middle level, then long press to eco, then turn off, then turn on again and ‘taa-daa’ you’re in eco again.This problem has appeared quite recently and is really disturbing.

I have to admit that it is a ‘new version’ of the fc-11 model.

If you have any ideas of how to make this bugs gone, it would be really nice!

However I believe that all these problems are refer to my own instance only and hopefully will not occur anymore else.

In any case I’m really thinking to get myself 2700k version though.

Cheers!

Whenever a light starts going mental, check allllll the retaining rings.

If one’s loose, tighten it. If they’re all tight, loosen them, jiggle the board to make sure it seats correctly, then retighten.

You have no idea how many mental lights were fixed by just doing that.

Thanks for the hint! The hack is that this flashlight hasn’t got any retaining rings inside. The driver as well as a bezel seems to be glued.

All I can do is to clean contacts.

The flashlight did not fall or sink, no dust inside, cell wrap isn’t damaged, nothing moves or dangles inside…

Never mind! That’s not that big problems for the 25 bucks light.
