Thanks for sharing.
I usually prefer using rechargeable batteries rather than built in recharging, so that if needed I can swap the battery and still use the light rather than wait for it to recharge, especially now with such small portable rechargers.
I did have to look a couple of them up. The Fenix PD36R and Jetbeam KO-02 look most interesting to me.
While in the Navy, I carried and used a Fenix light for several years. It took a lot of abuse and never let me down, so I trust them. I also like that the 21700 battery is a standard battery that could be replaced or also charged outside the light.
The Jetbeam light not only uses a standard 21700 battery, but is also compatible with other standard batteries like 18650 of which I have several.
The Skillhunt light sounds good with the capability to accept AA as well, but I am skeptical with its claim of 750 lumen.
