    SEO 3 Battery Operated Headlamp


    A shining example. Both in terms of battery life and price.
    An ideal entry-level model, the Ledlenser SEO3 comes in green and orange and has an ideal price-performance ratio. The SEO3 runs on regular AAA batteries and on the lowest setting the light can last up to 40 hours1. You focus it with a rotary switch and it is overall very easy to use. It also sits lightly and comfortably on your head. What's more, the headband can be removed and washed.
