Sofirn SP10B - Impact resistance issues?

Thanks for the heads up. I was debating whether to take this light with me on my upcoming vacation. Now I know I am not going to. :slight_smile:

If I were Sofirn Iā€™d want those drivers sent back to me to figure out whatā€™s going on . Same with the UT01 driver that has so many issues. what do these drivers have in common and is there a overall better design used by someone else ?

Hello!

No news about this issue?
Just pondering about buying 2 SP10B ore not.
I had them in the cart when I found this topic which previously escaped my attention.

Thanks!

i have ordered blue sp10b and hope for the bestā€¦couple of days ago mine sofirn sf10 drop from my lap while standing up from the sofa onto tile floor and nothing happensā€¦flashlight still worksā€¦not a scratchā€¦

but, to be honest, sf10 looks like the sturdiest of ALL sofirn flashlights be it sf or sp seriesā€¦it looks it could survive quite a good beating :slight_smile: sp series looks fragile to me in generalā€¦

Hi korfoto! Welcome to BLF!

Well, about this issue, the only things I can tell you is that my friend managed to get a new flashlight from Sofirn. He sent the damaged light to Sofirn as well!
About me, I bought a new driver for the SP10B host and I bought a ā€œnewā€ SP10A :smiley:

I wanna believe that these were all some ā€œnot so goodā€ examples and that Sofirn managed to / will improve their design :wink:

Thank you!
Long time lurker, first time poster here. :slight_smile:
I reckon that Iā€™ more concerned as I want one of them to be gift for somebody.
How is the ā€œnewā€ SP10A performing? I think you didnā€™t try to drop it as well. :smiley:

Eheh, glad you posted :wink:
Well, the ā€œnewā€ SP10A is still on the way as I ordered it last wednesday :smiley:
The old SP10A, I gave it to my girlfriend but never tried to drop it, so I donā€™t know how tough it would be :laughing:

But the new oneā€¦Iā€™ll try not to drop it :stuck_out_tongue:

The led on my first one came off. Sofirn sent me a new one no questions asked. Didnā€™t want the old one back. Gave me a good opportunity to learn how to reflow an emitter. Now I have 2 . :smiley: They are nice little lights with nice neutral even beam patterns.

Iā€™ve been EDCing mine in my pocket for quite a while already, and no problems so far, thank Bā€™harni (pbuh!).

But you did not drop it, neh? :slight_smile:

Thankfully, no. I try not to.

Frankly, unless I do it up myself, pot the driver, seal everything up tight, I donā€™t count on any claims of drop-resistance, water-tightness, etc. Some bozo at the factory could run short of O-rings and keep assembling lights without them anyway, yā€™know? So even if everyone elseā€™s is perfectly water-tight, you might be one of the lucky 0.1% whose light is missing a critical O-ring. And unless you take it apart first, or give it an unfortunate dunk, youā€™ll never even know.

How did that happen? :open_mouth:

Just happened. One day it stopped working. Unscrewed the head to find the emitter off.

Take more than one lightā€¦. or get a Zebralight and drop it as much as you like

Iā€™m impressed with Sofirnā€™s attention to this thread. :sunglasses:

It sounds like their light has a problem, but they are taking direct action to address it. Hopefully, theyā€™ll figure out what is causing the problem and fix it for future manufacturing runs.

I bought an SP10A and a SP10B. They both arrived today. The SP10A failed with the same symptoms as reported in the OP. The difference is I didnā€™t drop it. I just swapped the AA NiMH for a 14500 and the flashlight flickered and quit. It tried to start a few times but is now inert.
Iā€™m thinking bad switch or flaky driver. This one will be going back to Amazon for replacement.

ahh, you guys are gonna make me regret my decision to order blue sp10b :person_facepalming: i am thinking maybe better choice was to get another sf10, it is cheaper and looks more reliableā€¦

Check to see if the emitter is attached. The head has to be removed because the spacer will hold it in place with reflector in it. Mine flickered before it died. Iā€™m guessing cold solders.

I have a blue and a red SP10B on order, when they arive I will do some throwarounds on the oak floor and see how they fare after that.

I took my chance and I ordered 1 red and 1 blue.
The waiting process begun. :slight_smile:
