If your main goal is to buy a lighting fixture that emits high levels of brightness, you should look at the number of lumens. Watts measures energy use and not lighting output. This means that 2 bulbs that have the same amount of watts can have a different amount of lumens (brightness). Watts are a unit of power that measures electricity, whereas lumens measure brightness. This measure is the international standard for lighting output measurement and it is part of the SI system. LED lights are often labelled with their light output in lumens and, in many countries, this specification is required by law. The higher the amount of lumens, the brighter the light is.
To put it simply, lumens measure the brightness of a lighting source. They measure the total quantity of visible light emitted by a lighting source per unit of time. Lumens are the international scientific unit for luminous flux. We will also give examples of the minimum amount of lumens required for different light types. This quick guide will explain how this metric works and why it is crucial. In simple terms, the higher the amount of lumens, the brighter the lighting source is. Lumens (lm) are a measure of the total amount of visible light to the human eye from a lighting source. One of the most common specifications you will find when browsing for garden lights is the number of lumens.
