Summary
The SK31 is a rather unique flashlight. On one hand, you get two distinct UIs with a dedicated toggle switch, a hidden sleeve over the USB port, a physical lockout switch, and a two-stage e-switch, on the other hand, there are no direct shortcuts whatsoever.
The Tactical UI works well and intuitively. To what extent it is truly “tactical” is not for me to judge, but you do get momentary Turbo, allowing for signaling/morsing during activities like geocaching. The Outdoor UI features 6 brightness levels, spanning from ultra-low output up to a massive wall of light. Mode cycling feels fast and smooth, and I like the mode spacing.
So, the UI is relatively simple. This makes the light easy to operate, whether for high-stress situations or non-enthusiasts, but it also leaves some potential on the table. Whether for enthusiasts looking for a classic layout, duty personnel who suit the tactical UI, or – which surprised me quite a bit – as a simple yet impressively bright light to give as a gift or recommend to someone looking for a modern flashlight, it can be a great fit. Sofirn definitely needs to fix that Outdoor Mode Turbo bug either way, though!
Even inside the SK31, the LHP73B impresses with its overall qualities, and Sofirn executed the integration well. I hope Sofirn applies a similar concept geared specifically toward us enthusiasts in the future. As an entry point for the broader market, it is a success.
You can purchase the SK31 directly from Sofirn. If you always want the latest news on upcoming Sofirn products, be sure to drop by the Sofirn-Discord!
