Lux & lumen bij LED zaklamp en fietsverlichting

Lux & lumens for LED flashlight and bicycle lights

When choosing lighting sources such as flashlights or bicycle lights, understanding the difference between lux and lumens is essential to making the right choice for your needs. Lux and lumens are both units of measure used to measure the brightness of light, but they represent different aspects of light intensity.

Lumen (lm) refers to the total amount of visible light emitted by a light source. In other words, it measures the total amount of light produced by a lamp, regardless of the direction in which the light is emitted. The higher the number of lumens, the brighter the light source will shine.

Lux (lx), on the other hand, measures the intensity of light on a specific surface, expressed in lumens per square meter (lm/m²). It tells us how much light actually falls on a given area. In other words, lux measures the brightness of light as perceived by an observer at a certain distance from the light source.

When selecting LEDs for flashlights or bicycle lights, it is important to consider both the lumens and the lux value. An LED with a high lumen count will generally produce a brighter light, but the lux value will determine how concentrated that light is and how far it can travel. For flashlights aimed at long-distance lighting, such as searchlights, a higher lux value may be important. For bicycle lighting, a wider spread of light can often be more useful, especially for illuminating the road surface.

In short, when choosing lighting sources, it is essential to consider both lumens and lux values ​​to ensure you get the right amount of brightness and coverage for your specific application.
