Flashlight Lumen What Is It and How Much Do You Need

Flashlight Lumen What Is It and How Much Do You Need

When night falls, visibility decreases and we need light to see clearly. An Olight flashlight can meet this demand for light.

But for different application scenarios, how many lumens can meet the requirements?

In fact, there are many factors that affect the choice of flashlight. For example, how large an area can be illuminated, the running time of the flashlight, certain special features or price. In this article, we give examples of how many lumens a flashlight should have in different application scenarios.

What are lumens?

Lumen (Latin for light, lamp) is a unit of luminous flux. Therefore, this value represents how much light (technical term: how much light) the light emits in total per unit of time.

The light output of a flashlight is measured in lumens, the more lumens, the higher the light output. Therefore, this important information can be seen directly on the product packaging or prominently displayed on our website.

Depending on the field of application, different powers are required. For example, finding people in a dark forest requires a much higher lumen output than lighting a small room or tent.

▪️ ≤ 150 lumens: night light, tent light, reading light, backlight

▪️ 150-500 Lumens: Simple everyday tasks indoors and outdoors

▪️ 500-1300 Lumens: Walking and night jogging, camping, maintenance, fishing

▪️ 1300-3000 lumens: outdoor sports, hunting, exploration, caving, tactical tasks

▪️ 3000 Lumens: Hunting, Law Enforcement, Military, People Search
