This thread was my introduction to the flat lights - i may have to try one
At first i thought you guys' were carrying around your Apple TV remote
I've carried a round style flashlight clipped inside my left front pocket for probably 16-17 years now. The flat ones are so much more comfortable.
However, the ones I own, the Olight Arkfeld UV, have the button on the side, which makes it practically impossible to use it in a defensive role. Therefore, I haven't completely retired the round style lights yet.
I'm really digging the Streamlight Wedge XT, but I'm not crazy about it's 2 stage UI. If it could be programed for high only, I'd own one. But high/low or low/high won't work for me. Maybe they'll add that feature in the near future.
