Review on COSOOS 2 Rechargeable Headlamps: 500 Lumen Bright LED Flashlights for Camping, Running, Hiking & More! by Christian Young

These lights are very good. They offer a good amount of light to illuminate your surroundings. Not as bright as a normal flashlight, but illuminates a large area better. Being rechargeable is good, but one of the flashlights doesn't have a very good battery and dies within a night of use. The other lasted at least 3 nights camping before needing to be recharged. I contacted Revain and they refunded me half the price as it was outside the return window. Not the most human-friendly light. It is very bright to look at, so it is difficult for others to look at you. Perfect for the onset of winter when it's still dark in the morning and you want to get under the cars.
