Summary

Great hardware, poor software – that’s the Sofirn SK31 in a nutshell. The combination of a powerful LMP LHP73B with a well-regulated driver, a two-stage tail switch, a separate switch for the lockout and a screwed cover for the USB-C charging port provide the perfect hardware foundation for a great flashlight.

The operation is all the more disappointing. The two-stage switch leaves much of its potential unused. For example, there is no direct access to the lowest or highest brightness level and in Tactical Mode, the switch must be held halfway down for a full five seconds to keep the flashlight on. Minor firmware bugs make the overall experience even less enjoyable.
