This is a used item, but I've replaced the batteries with new ones and tested the light! No problems. I think it's a good product with little signs of use. It's an older model, but it's packed with features like a whistle, red light, and flashing mode. Comes with a wide-angle lens. ＜Product Details＞ Manufacturer Part Number: E99PN Weight: 88g (including batteries) Luminous Flux: 80 lumens Beam Pattern: Spot, Wide Maximum Burn Time: 80 hours Economy Burn Time: 190 hours Maximum Beam Distance: 68m Economy Beam Distance: 21m High-output white LED Red LED: Not too bright, suitable for use inside tents or mountain huts High Functionality: White light / 2 levels of illumination (maximum, economy) and flashing mode, Red light / 2 modes (continuous, flashing) Switchable spot beam and wide beam (opening wide-angle lens)
