Lux Levels Chart

Our lux levels chart details the light levels required for lighting the average space, depending on their use. This will help you choose the perfect indoor lighting and lamps for your home or business.

It is important that you get the right lighting levels in a room, as it can cause a number of detrimental effects on a person’s mental and physical health. Side effects can include eye strain, headaches, tiredness and fatigue, neck, back and shoulder strain and even depression.

What is Lux?

Lux is a measurement of light intensity, commonly referred to as 'illumination'. It measures the amount of light present ion on a particular surface as measured human eye. In essence, this is light intensity within a specific area. The purpose of lux is to provide the number of lumens needed to sufficiently light a given space. For example, a sufficiently lit office requires around 500 lux.

What is a Lumen?

This is a common way to identify the strength of LED bulbs, so it's important you understand what it means. A typical LED bulb will have the lumen level indicated on the packaging.

The official measure of illuminance is in Lumen. Lumen is another way to measure the output of light i.e. the brightness. It measures the emitted light per second from a source but doesn’t consider the light’s direction. Put simply, the higher the lumen, the higher the brightness/output of the light.

One Lumen per square metre equals one lux, so it is easy to convert the two. Unlike Lux, Lumen doesn’t consider the direction of the light or the space the lighting is filling. Therefore, it shouldn’t be considered in isolation. Both Lux and Lumen should be considered when selecting lighting.

Watts v Lumen & Lux

Watts measures a light source’s power output rather than the level of brightness. New, energy-efficient technology now means that using watts isn’t an accurate indication of a bulb’s power. As technology continues to improve, more lumen will require fewer watts, improving energy efficiency. Do not use watts as an indication of a bulb’s brightness, as it simply doesn’t give an accurate representation. 

The importance of good lighting cannot be overestimated. It is important you understand what the numbers on the packaging mean, plus which lighting level is suitable for the intended room. A larger number doesn't necessarily mean better, especially when considering watts.
