This is the Lumintop "Duke" flashlight. It's brand new, with the body still in its vacuum-sealed packaging and the outer box unopened. 【Shipping to Hokkaido and Okinawa is not possible.】 Key features of this light: * Operates on a 14500 lithium-ion rechargeable battery or one AA battery (batteries not included) * Body made of a combination of stainless steel, brass, copper, and carbon fiber * LED is Osram (P9, same as Tool AA 3.0?) * Maximum output of 800 lumens * Output has 3 modes + strobe * Includes a USB-to-USB-C cable, spare O-rings, and a lanyard The size is as shown in photo 5, only slightly larger than the company's Tool AA 3.0. As shown in photo 6, there's an indicator on the top of the switch that lights up when the light is off, and you can configure this indicator to be on or off. Unlike the Tool AA, you can't loosen the head slightly to turn off the indicator. The feel is smooth, and the design is elegant, so it seems like it would be suitable to carry in a suit pocket. It uses copper and brass, but I'm not sure yet if it will change color due to oxidation. The copper model of the Tool AA oxidizes, so I think this one will probably do the same.
