I find it peculiar that there's so many arguments to the R1, but most in this thread revolve around:
Charge port design...No one as taken into account weather resistance, or simplicity. A converted computer spec cord is not needed for simple charging.
Is it a true "duty" light? However that may be defined; under my definitions (tac light vs. duty light), it's more of a hybrid.
Discharging after charge: Never experienced that, and mine is a very early model. Maybe an issue later on in production?
Output...There is no need for these lumen monster lights in day to day "duty" usage. I'd rather have less output, longer runtime, and a light that won't become too hot to the touch. 300-500 Lu is ideal, 750 is pushing the limits of usage. 1000 is too much.
Proprietary battery...This is a BIG negative. I haven't taken one apart, but it does not seem as easy to modify as a Streamlight Strion proprietary cell (at least that style is also used by Nite Eyeze in the T4). Sure, the R1 comes with a CR123 cradle, but that defeats the purpose.
Multiple modes...ugh...single output, only. I've experimented and used strobes on duty, but there are very few lights that have a Hi-Strobe option. Most have a hi-strobe-lo option, which is useless.
