No lockout. That’s about my only real gripe with this light. I have one of the bad ones, purchased in May. Tracy had a replacement sent within a couple of days. I’ve had both apart, and there is no difference in the driver. Same model/ revision number. I think they pulled them from Amazon, when they started having issues. It isn’t an issue that will just appear one day, either. It will show up as soon as the light gets heated up. (Or at least thats what everyone, including myself, experienced) Never did figure out exactly what was causing it.
One thought for Tracy/Sofirn — check your driver circuit for susceptibility to “electronic smog” like a cell phone operating nearby.
I have seen other electronics from China that would turn on or off if a cell phone or walkie-talkie radio operated nearby, for example.
I also noticed I could trigger a neighbor’s car alarm by changing modes on a flashlight as I was walking near it (a few years ago, I no longer have that light— not one of yours)
Thank you very much for you guys kindly feedback of Sofirn light.
SF11 was something wrong in June but we have completely destroyed that products on Amazon and made improvement.
If you met any problem or question, please feel free to contact the sales servers and they will do their best to assist you to solve your problem as soon. We 100% stand with our customers.
Would a new version of the SF11 be coming out soon?
I’m getting to like that form-factor, and it’s just a nice simple but elegant design. Very clean.
Improving on the TK4A would make the SF11(A?) a winner. Keep the same UI as the TK4A, but make doubleclick turbo/100% instead of strobe, so this way you’d have instant access to both its lowest and highest settings.
The reflector of the TK4A seems to have some very fine leftover machining marks, making the beam slightly ringy. Smooth it out, and you’d have a perfect beam!
And it definitely needs 2 screws to hold down the emitter.
Tracy, do you only provide these deals with codes by Amazon? I get get anything shipped to Sweden from Amazon. Can you offer discount codes on AliExpress or similar?
Going to be posting a review tomorrow for the SP10B, and holding a giveaway for 3 lights. 2 to the US (Red and Black), and 1 (choice of color) to anywhere else in the world. I will also post the same coupon codes for Amazon (US, non-affiliate code) all three colors.
Thanks for your interested in Sofirn light.
Maybe you can buy these light on Amazon.UK, right? Which one do you want to purchase? Please pm and we would love to offer a code for you. Thanks
Amazon UK can ship to Sweden, but then it’s much more expensive than ordering directly from AliExpress.
I’m really interested in the new Sofirn C8F Triple XP-L W2. I just sent you a PM.
I think your range of flashlights is too big and the model name/numbers are not memorable. Many models look very similar to one another and every time I browse your Aliexpress page I get confused.
In the ‘product description’ of some flashlights, you show 6-7 pictures of other lights. It is ridiculous! In product description I want to know features/spec of the flashlight I am looking at, not confusing pictures of other lights. Very bad store design.
I ordered Sofirn SF36 Warm White LED and Sofirn SF32A from Amazon but it was not shipped to my zip code (HI, USA)
Can you offer discount codes on Banggood?
