Sofirn SP10B - Impact resistance issues?

Eep! I think switches may be the weak link in any light, ’cause of my recent experiences with a TK4A. Slap-therapy helped it, though, and it’s working fine now.

Other possibilities might be loosening the driver and breaking the connection to ground. Jiggling it, reseating it, tightening any retaining ring(s), etc., might fix it.

I had driver issues look like a switch problem, switch issues look like a driver problem, etc. Once I was kinda panicked that my trusty SF31W might be going mental, but it was just a loose retaining ring that was holding in the driver. (No ground, no light.) Snugging it up carefully fixed it and it hasn’t misbehaved since. Whew! :smiley: :beer:

The tough part about side-clickies is that you can’t just take the switch out of the equation by jumpering it with a key or screwdriver. If it doesn’t light up, it just doesn’t light up.

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 I’d want those drivers sent back to me to figure out what’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 best…couple of days ago mine sofirn sf10 drop from my lap while standing up from the sofa onto tile floor and nothing happens…flashlight still works…not a scratch…

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

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 “new” SP10A :smiley:

I wanna believe that these were all some “not so good” 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 I’ more concerned as I want one of them to be gift for somebody.
How is the “new” SP10A performing? I think you didn’t try to drop it as well. :smiley:

Eheh, glad you posted :wink:
Well, the “new” 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 don’t know how tough it would be :laughing:

But the new one…I’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. Didn’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.

I’ve been EDCing mine in my pocket for quite a while already, and no problems so far, thank B’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 don’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, y’know? So even if everyone else’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, you’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 light…. or get a Zebralight and drop it as much as you like

I’m impressed with Sofirn’s attention to this thread. :sunglasses:

It sounds like their light has a problem, but they are taking direct action to address it. Hopefully, they’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 didn’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.
I’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 reliable…

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. I’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.
