Mine just showed up yesterday. Will be doing a review soon. Initial impressions are great. Sure, I’d love if it ran Anduril, NarsilM, or RampingIOS… but short of that, it’s been good so far. Bright, compact, USB-C charging, ramping option with single click on/off, etc.
… and after my review is done, I’ll crack this thing open and see what chip it’s running and if I can give it a brain transplant
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,
Thanks a lot for posting your observations, g_damian. I will let Wurkkos know about this UI issue, so they become aware of it. Hopefully, this will be rectified in revison 3.0 of FC11 (with type C-C cable support). 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. The same will probably apply to the missing anti-reflection coating on the glass lens.
I want to add that the UI is changed now. There is hold from off for moonlight, and no more long press to turn off. The bug g_damian mentioned exists but seems like it doesn’t effect normal use too much.
I swapped a 3500k LH351D into mine, I’d suggest those who like warmer LEDs try it. The stock 5000k LH351D had enough green tint to bother me, I have some of the “dogfart” LH351Ds that seem less green.
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.
