This small but useful and practical companion weighs only 22 grams. It has a built-in Li-Ion battery in its strong aluminum frame, which can be charged via an internal Micro-USB-C port after unscrewing the device. The surface has a special design reflecting Olight's 16 years of existence. Its light is provided by a high-performance LED. This and the TIR optical lens provide soft, diffused light. Its brightness can be easily adjusted in two stages by turning the head of the lamp. The i16 is a perfectly practical and easy-to-carry device with a performance that belies its size, which can be of great help to its owner thanks to its easy charging and usability.
