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.
