Sofirn provided me with a sample of this flashlight for review. I was not paid to write this review. I have not held back on any negative opinions of this light.
Sofirn SP31 V3 Written Review/Transcript:
General thoughts after a week of usage/size comparison/practicality/interesting things:
• So many of you would know I’m a regular user of 18650 tactical lights. This form factor is perfect for EDC while remaining powerful enough and providing sustained runtimes. The Sofirn SP31 V3 is the newly released version of the SP31, and it’s earned a place in my top 3 budget tactical flashlights! There are a lot of tactical-style flashlights out there, but they lack that one-step shortcut to turbo and momentary mode, both of which are included in the SP13 V3. One surprising feature is that this light included a regulated buck driver!
• What’s in the box? 18650 battery, lanyard, spare o-rings. My sample version did not come with a manual
• Other comparable flashlights: SC31T, Wurkkos TD02, Wurkkos FC12, Convoy S8
Overall Construction, LED, lens, bezel and reflector
• I think Sofirn is on the way up - I like how they apply feedback from the flashlight community. It’s working as with each iteration, they make small tweaks that add to the overall quality/usability. The machining on the SP31 V3 is excellent, especially for this price point. Some cutouts on the head, and deeper knurling on the battery tube. Sofirn has been using this new matt black anodizing that I like more than its previous glossy finish. It’s grippier and looks more premium. The clip is improved too, with greater rigidity. Tactical switch on the rear with momentary mode and metal side switch (which also has a battery indicator function). One of my annoyances with the SC31T was the rubber side switch. Overall, the SP31 V3 feels very durable, and reminds me of the Wurkkos TD02, except with proper tactical functionality.
• SST40 with recessed TIR lens/Glass lens on the front. The bezel is glued on. No crenulation.
• Takes an 18650 cell. Light can only unscrew from under the head. The tail switch is glued on for some reason. Onboard USB-C charging with a solid rubber port.
UI - modes
• Must activate the tail switch first. Half-press for momentary memory mode, full press for constant on. Press the side switch to cycle LMHT. I set mine to turbo before switching it off for 1-step momentary turbo.
• Moonlight mode - hold the side switch, then press the tail switch.
• When on, press and hold the side switch for the strobe. Single press to go to beacon and SOS. Single hold to go back to LMHT.
Performance - total output, beam profile, longevity, practicality
• Ceiling bounce test, CRI, CCT:
• Surprisingly throwy beam. Need to ramp it up to medium-high for decent spill.
Considerations
• SFT40 would have been better in this light. This seems to be the standard for most 18650 tactical lights, and results in higher candela. The SST40 still performs well in this light though.
• Hope to see Sofirn implement USB-C charging under the bezel for this light - more of a design suggestion.
Verdict
• The SP31 V3 is one of the best value tactical flashlights out there right now. It comes with everything you need straight out of the box, for a great price.
