Sofirn SP10 V3 Review

I’ve got an SP10 V3 from Sofirn for review – here are my thoughts about this light.




Update: Got some codes from Sofirn:

https://sofirnlight.com/
5% OFF
Code: HLA8O6C4

Amazon US:
SP10 V3 Kit: 35% OFF
Code: 20VRI7U9

SP10 V3 alone: 40% OFF
Limited offer, leave your comment down below and Barry from Sofirn will message you the code if one is available.


You’ll get (in the kit version):

  • Flashlight
  • Two-way clip
  • Lanyard with little carabiner
  • 2x replacement o-ring
  • Micro-USB cable
  • Single cell charger (Xtar MC1 style)
  • 14500 Li-Ion battery with 900 mAh

Dimensions:

Length: 88 mm
Diameter: 22 mm
Weight (without battery): 39 g


UI:

  • 1C: on/off
  • 1H from on: change brightness (low → med → high)
  • 1H from off: moon mode
  • 2C: turbo; 1C back to previous level or off
  • 3C: strobe; 1H to change to SOS and beacon
  • 4C: lockout with momentary mode; 4C to exit and return to previous brightness

Power supply:

This is a multi-chemistry flashlight supporting various batteries:

  • 14500 Li-Ion (2.8 – 4.2 V)
  • AA rechargeable and non-rechargeable (0.9 – 1.5 V)
  • AA lithium primary (0.9 – 1.5 V)

The 14500 li-ion results in highest output up to 1000 lm (not measured), but only for a short time and the output is not regulated, i.e. the brightness depends on the battery voltage. Also the quiescent current is relatively high with 143 µA.

Much better with a NiMH rechargeable battery: Only up to 300 lm, but regulated, stable output. Not as hot, but still a stepdown after 90 seconds. Quiescent current only 33 µA!
Alkaline batteries are supported, but might not deliver the same performance and are not good for our environment. Smile

If you don’t use it often, but want it for a backup light in the car with low temperatures: Use AA lithium primary batteries with 1.5 V.

There’s a spring in the tailcap and a brass contact with mechanical reverse voltage protection in the head. Thus only button-top batteries are supported.


Driver:

  • Weird stepdown behavior starting after 90 seconds
  • Levels are regulated with 30 kHz PWM (except moon and turbo)
  • Boost regulator seems to run at about 333 kHz
  • There were some reports of damaged drivers in the first batch, but Sofirn said it was resolved

Beam and usability:

First the usability: The sideswitch is very smooth and flat, thus hard to find by feel, but also less likely to actuate in the pocket. Some grip tape might help.
The tail has two holes for a lanyard. Sadly there are also big cutouts which make tailstand less stable.
The rest is the usual Sofirn style and quality, no complaints.

The beam is very nice. Floody with a touch of spot. Very good for indoor as well as close range outdoor. Samsung LH351D with 5000 K and CRI 90. Slightly green, of course, but acceptable.


Positive:

  • Multi-chemistry, good AA light (still waiting for the Anduril version – that will be awesome!)
  • Not ultra compact, but still small.
  • Good runtime on NiMH LSD (e.g. Eneloop)
  • Good compromise between efficiency and output with the LH351D

Negative:

  • Weird stepdown behavior
  • NiMH has unnecessary stepdown after 90 seconds
  • Tailstand unstable
  • Clip could be stronger

Conclusion:

IMHO this light has its strengths in the AA NiMH support – li-ion just to get the high numbers. Nice beam, good CRI, simple UI. The version with Anduril will be awesome, but this will be a very good alternative for people who prefer a simple UI.

Great review, does look like an interesting light.

900mAh right?

Also you might want to mention the battery draining defect on a batch of these.

Oops, you’re right, thanks! A small but major typo! Facepalm

I had mentioned it in the driver part, but added a link now.

No worries, we have all made transcription typos.

Missed that, but thanks for the link.

Nice review, thanks! I'm not a fan of the changes of the switch and tail but looks more and more like this will be the host of the Pro version frown. Maybe I can move the Pro driver over to the V2 versions I got.

If I look at snow it looks not so “slightly” green. I just is green.
