Easy to understand graphic explaining the difference between lux and lumens as well as a conversion calculator.
Here are a few key points explaining why paying attention to lumens is so important when choosing lighting fixtures. 1. Scientific basis for brightness perception Unlike watts, which mainly reflect energy consumption and cannot directly indicate the brightness of a light fixture, lumens are directly ...

total light (measured in lumens) than any smartphone, but the phone packs more light into a smaller space. That’s why using a phone during a movie is so taboo: with at least ten times the candela per square meter than the screen, it’s basically a magnesium flare in a dark theater....
Lumen - Unit of Luminous Flux In a lamp, electrical energy is converted into radiant energy and emitted. Only a portion of that radiation is visible light; the rest is heat (infrared). The total amount of visible light that a lamp emits in all directions is expressed in lumens. Only ...
What they have in common is the extremely high CRI (and CQS, TLCI, TM-30-20). In each product page, you will find photometric reports that show all these readings.Comparison of High CRI LED Strip Lights Below you will see a comparison between the brightnesses (lumens per foot) of each...
Whereas lumens are a measure of the total amount of visible light emitted from a source, lux is a measure of the intensity of light in the usable portion of its beam pattern. This means that two lights with identical lumen ratings can have very different lux measurements, depending on how ...
Theluminous fluxis similar to a quantity of (light) energy, and if you spread it over a larger surface area, the light will become dimmer. For instance, if a luminous flux of 1000lumensis spread across 1 square meter, that’s 1000 LUX. If 1000 lumens is spread across 10 square meters...
When necessary to avoid confusion between these 2 meanings the term 'perceived light' may be used in the first sense' and 'NOTE 2—Light is normally, but not always, perceived as a result of the action of a light stimulus on the visual system.' [This latter note was added even before...
When replacing bulbs, check the lumens to ensure sufficient brightness. 4 Lumen Critical in environments where precise lighting is crucial, like in laboratories. High lux levels are maintained in lab environments for accuracy. 3 Lm A unit of luminous flux equal to the amount of light given out...
