Petzl e+LITE Headlamp Model: E02P4 Purchased October 2017 Used only once in the mountains, and then I haven't had a chance to use it, so I'm putting it up for sale. I will ship it with new batteries that were used for the function check. The original box and instructions are gone. From the website: This is an ultra-lightweight (26g) and ultra-compact emergency headlamp that is convenient to carry. It comes with a protective case, making it suitable for carrying in a backpack pocket or emergency kit. It can be stored for 10 years in a ready-to-use state, making it ideal as a backup headlamp. It has red and white light, with a maximum of 40 lumens of continuous light and a flashing mode. A whistle is attached to the back of the elastic headband for use in emergencies.
