What is the difference between lux and lumens?
Lux and lumens are both units used to describe light, but they measure different aspects of illumination.
Lumens (lm) measure the total amount of light emitted by a source, such as a bulb or fixture. It indicates
the overall brightness produced by the lighting device, regardless of where the light falls.
Lux (lx) measures how much of that light actually falls on a surface. It is calculated as lumens per square meter and represents the level of illumination experienced in a specific area.
In simple terms, lumens describe the output of the light source, while lux describes the light available on a working surface.
In the Indian industrial context, lux is more important for workplace safety and productivity because it directly reflects lighting conditions in areas such as factories, warehouses, construction sites, offices, and inspection zones.
At Uniquo, we focus on lux testing through illumination surveys to ensure that workplaces across India have adequate and uniform lighting as per safety and operational requirements.
