I received my T27 yesterday and after a quick charge, took it out for a late night test.
I love the tightly focused lonnnng beam, the small form (for a long thrower) and the two-switch UI. The quick access to turbo via the tail switch is exactly right. The comprehensive UI from the side switch is straightforward.
I have several single cell throwers that are rated 700 meters. The T27 is a solid step up in range and brightness. Spill is just right. If you are a night bird/game watcher like I am, this is an excellent torch.
My T27 is fitted with the XHP35 HI 5000K emitter; the tint seems perfect to my eyes: bright white but not cold.
Good ergonomics/nice balance for using either switch.
Good heat management.
The box comes with everything: Hi-capacity/high drain 21700 battery, fast-charging USB-C cord, holster, clip, lanyard, O-rings, spare button.
A thumbs up discovery: The head, wide as it necessarily is, fits nicely in an automobile cup holder.
Tolle Taschenlampe! 5
Super Reichweite und Battery Laufzeit ist ebenfalls gut!
