Lux Level Guide - What is It, Calculation Method and Application Area Requirements Explained!

Lux Level Guide

Similar to various sectors and segments, the lighting industry has recently undergone rapid technical and non-technical advancements. As a result, we have multiple options nowadays available in different category lightings to choose from.

However, unlike non-technical prospects, there are many technical aspects, such as lumens, CRI (Color Render Index), Multifunction sensor, and Lux Level, which are hard to understand in general terms.

But, as a point of general knowledge, these terms define the quality level and play a vital role in improving specific areas lighting efficiency.

In this blog, out of various technical prospects, we have decided to inform you about the Lux Level of advanced LED lighting - what it means, how to calculate the Lux level and which area gets the most benefit from it?

So, to begin with:

What is Lux Level?  

Lux level, primarily known as DIALux, refers to the standardized unit measuring the intensity level of LED lighting. It is also popularly referred to as "illuminance" or "illumination".

It calculates the lighting intensity level that directly falls or reflects on the surface and walls of the installation area.

With the advancement in the lighting sector, almost all LED lights are equipped with high-intensity Lux Level, offering brighter illuminance for a more extended period than usual.

LUX Level Calculation Procedure! 

The LUX is calculated in the metric SI system. 1 Lux = one lumen/ sq. square meter. It varies from lumens, which calculates the source light brightness. Therefore, 1 LUX = 1 Lumen / m2

A perfectly balanced luminance is essential for visual clarity, eye effectiveness of the ocular functions and contrast sensitivity.

Whenever you plan to install LED lights in your preferred areas, you should aim to buy lighting products that are well balanced from every technical and non-technical angle.

Wrong LED lighting selection might lead you to mishaps and hassle. Access Lighting is terrible for eyesight and leads you to many visual problems.

For example, we need more bright lights while stitching, drafting, reading and writing, whereas walking and eating can be done under standard lighting.

When you go for commercial spaces lighting shopping as per the lux level, you need to consider the varieties of lighting you require from different places of your commercial buildings because a storeroom lighting intensity will significantly differ from the workshop areas.

However, 750 lux level is ideal for any commercial building as it brightens vast areas while ensuring no mishaps and hindrances to products 0r eyesight.

Educational Spaces: 

The perfect lux level of any educational sector ranges between 300-500 lux. According to lighting experts, these lux levels range ideal for studying (reading/writing), providing efficient illuminance and not hurting students' eyesight.

However, in teacher-centric areas, you should consider installing 700 lux level LED lighting to increase students' focus on the blackboard/display so that they can pay close, in-detail attention to tutor and their teaching methods.


You must have noticed the massive hanging lights and some varieties of other lights in supermarkets.

Healthcare Facilities: 

We know how vital the role lighting plays in healthcare facilities. Not just in operation theatre but all over the place as healthcare spaces are crowned 24/7.

Looking at modern-day's healthcare architecture (High buildings, different small, medium and large rooms), we believe that a standard 100 lux level light is enough to brighten the doorways and corridors.

In contrast, nursing stations require 150-300 lux level lights. While the laboratory lighting needs 750-1200 lux level, night luminaires will require 1 lux, and examination lighting can work efficiently on 200 lux level.

Other Spaces: 

Apart from the areas mentioned above, lux levels are essential for outdoor spaces such as streets, parking areas, garages, shipyards and many more hazardous locations.

LED lights contain higher lux levels than indoor lights in these areas for better and safer illumination.

Follow the below table to gather information about different lux level requirements in different spaces:

Spaces Light Level (Foot Candles) Light Lux Level
Classroom (General) 30-50 FC 300-500 Lux
Library (Reading/Writing) 30-50 FC 300-500 Lux
