Review: Wuben T102, a large 1x26650 light with USB-C

The Wuben T102 is a 1x26650 light with an XHP70 emitter, large reflector for respectable throw, sensor-based thermal regulation, USB-C charging and a boost driver that could provide stable output as the battery drains. Unfortunately, it doesn't, dropping to half output unless the battery is fresh off the charger.
