SEO3 Headlamp



The SEO3 is a great everyday headlamp perfect for outdoor adventures or to keep in your preparedness kit in your car or house. It offers up to 100 lumens of white light, with a beam distance of up to 100 metres. The lens is focusable, thanks to Ledlenser Advanced Focus System, which allows you to transition from a broad flood beam to a sharply focused long-distance beam. The SEO3 takes 3 AAA batteries to power up, and has a transportation lock so you don't accidentally turn it on. It also offers a red light to preserve night vision. View Product Details
