Got my grey Nightwatch NA40SE (3000k, 95cri) today: (the blueish tone is the effect of the CW Ledlenser K3 that I use to provide spot-lighting)
Spring-less tailcap, but a protrusion the size of 3mm (h) X 11mm dia. (not the same design in Tom E’s non-SE version.) Below is the previous tail-cap of the non-SE version (photo courtesy of Tom E): !
! The front of the tube has to be unscrewed to expose the type-C charging port: ——————————————————-Double O-rings at the back Nightwatch NA40SE beside the Nightwatch NS22 Seeker: Control shot —- NS22 (3000k, 95cri) —- NA40SE (3000k, 95cri)
