I also noticed rough edges on cooling fins and tailcap chamfers on my prototype sample and suggested Sofirn (manufacturer) to improve the manufacturing process. However, it seems there’s little margin left to do some extra post-treatment to those things as FC11’s price needs to be kept very low.

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.

  • there is a bug in ui: if turbo or strobe is accessed directly from off, long press activates last used mode. From that state, flashlight cannot be turned off and mode cannot be changed. Only action is double/tripple click to go back to turbo/strobe and then flashlight can be turned off,
  • there is a PWM detectable by phone camera (similar speed to bistro firmware),
  • high (~1.7A tailcap current) step down is after 5 minutes to 60% of initial high mode, which is almost equal to medium mode,
  • turbo (~3.9A tailcap current) step down is after 1 minute, lasts 30 seconds, so after 1:30 flashlight is on 20% of initial turbo mode, which is almost equal to medium mode,
  • standby: 1.41 mA initially, 0.03 mA (= 43 μA measured on different scale on my DMM) after few seconds,
  • eco: 7.67 mA
  • glass is not AR coated,
  • during charging flashlight can be turned on in low mode,
  • with charging cable connected flashlight can be turned on in low mode even without battery,
  • magnet is strong, flashlight can be attached to round pipe in horizontal position without an issue,
  • magnet in the tail is probably not glued and small rattle can be heard when flashlight is detached from a surface,
  • fins around head are rough,
  • tailcap lanyard hole area is also rough,
  • fc11 and convoy s2+ have the same size.

Overall pretty nice piece of lumens Smile


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

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.

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.

My Future's So Bright...well, my flashlights are anyways.

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

raccoon city – Thank you.

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.
