Understanding CandelaĬandela (cd) is another unit of measurement for light, but it focuses on the intensity of light emitted in a specific direction. Many consumers use the lumens measurement to determine the right lighting equipment for their needs, particularly when selecting Everyday Carry (EDC) items. Keep in mind that lumens should not be confused with watts, which is a unit of power rather than brightness.įor example, imagine a flashlight that emits 1000 lumens this indicates that the flashlight is quite bright and can cover a larger area when compared to a flashlight emitting only 200 lumens. The higher the lumens value, the greater the area that the light illuminates. This helps the users to understand the brightness of a flashlight, bulb, or any other light source. Lumens is a measurement of the total amount of light output emitted by a light source in all directions. Definitions and Basics Understanding Lumens This understanding will help you make informed decisions when selecting EDC flashlights for different applications and situations. When comparing flashlights, it is important to consider not just the total lumens but also the candela value.Ī focused beam with lower lumens can potentially have more candela than a light beam with more lumens but spread wider, making it essential to find the right balance for your everyday carry needs.
Knowing these differences allows you to select a flashlight that provides the appropriate brightness, beam shape, and range for various EDC scenarios or specific tasks at hand. Lumens and candela are both measurements of light, but they serve different purposes and provide valuable information about the performance of a flashlight.Ī lumen, abbreviated as (lm), is a measure of a flashlight’s total energy output or visible light emitted in all directions, while candela, abbreviated as (cd), measures the intensity of light concentrated in one direction.
