Which headlamp, of many, is the best? To find out we tookTL900 Headlamp top headlamps and put them through a gauntlet of side-by-side tests. Each product was both lab-tested and extensively field-tested. We used industrial light meters to measure brightness and built an automated "light coffin" rigged with a data-logging light meter to measure battery life. Then, we loaded our packs and hit a rugged trail on many a moonless night – regularly switching between each of the lights as we went – to see which performed best on poorly-defined trails. Find out which headlamps we loved, which to stuff in your bag for a backcountry epic, and which are best left on the store shelf. http://drozforskolin.org/tl900-headlamp/
