The 1000 lumen Handheld Flashlight is a very reliable, inexpensive, and multifunction flashlight. With many flashlights running on expensive lithium batteries, this light runs on 3 AAA or a rechargeable 18650 battery making it affordable to own over years of ownership. It features 100%, 50%, 10%, SOS, and strobe function by toggling the power switch. It also can be focused from a flood light to an extremely bright spot light. It is backed by Osprey’s industry leading no-nonsense lifetime warranty.
