What does lumen output mean in a flashlight?
Lumen output is a measurement of light intensity, the higher the intensity the brighter the light. When manufacturers rate their flashlights they use a light meter to measure the lumen output an thus giving you an idea of how bright the light will be, when we talk about flashlights their are other factors also to consider one of the most important is the size and design of the reflector matched with a suitable amount of lumens to achieve the results we want for a specific purpose, for example a 200 lumen pocket torch matched with a reflector diameter of 20mm may only throw its beam of light 30-40 meters but will light up the first 20 meter very well where as if you take the same 200 lumens and match it with a 55mm diameter reflector you will be able to have more focus and throw the light 100 meters so balance of lumens and reflector are important.Not everyone has a light meter so to give you an example of lumens in relation to commonly found identifiable flashlights we have compiled so
