Olight Lumens Explained
Lumens is brightness, not distance
Lumens measures total light output. A 2,000-lumen light is bright, but usually only holds that peak for seconds before stepping down to protect itself from heat. The sustained output matters more day to day than the headline peak.
Throw vs flood
A thrower focuses the beam for distance; a flood spreads it wide for close work. EDC lights like the Arkfeld lean flood; dedicated distance lights lean throw.
Runtime is the trade-off
Higher output drains the battery faster and makes more heat. You will live on the lower modes, so good runtime there matters more than the turbo figure.
What you actually need
Around the house / EDC: 100-500 lumens.
Outdoor / work: 500-1,500 lumens.
Distance / search: 1,500+ with real throw.
