Lighting Testing in the UAE: Why Workplace Lighting Matters for Comfort, Safety and Productivity

Lighting is one of the most important parts of a healthy and effective workplace. It affects how clearly employees can see their work, how comfortable they feel during the day, how easily they can focus, and how safely they can move around the workplace.

In offices, laboratories, clinics, schools, retail spaces, warehouses and industrial facilities, poor lighting can create problems that are not always immediately obvious. Employees may complain of headaches, tired eyes, glare, screen reflections, fatigue or difficulty concentrating, but without proper lighting testing, it can be difficult to prove what is causing the issue.

RMT provides lighting testing in the UAE as part of its environmental testing services. Using light sensors and lux meters, RMT helps companies assess whether lighting levels are suitable for the type of work being carried out, whether employees are exposed to glare or uneven lighting, and whether improvements are needed to support comfort, productivity and compliance.

What poor lighting does to a workplace

Poor lighting can affect both people and performance. It is not simply a matter of whether a room looks bright or dark. A workplace can appear well-lit while still creating glare, screen reflections, shadows, uneven brightness or eye strain.

The UK Health and Safety Executive notes that poor lighting can contribute to issues such as eyestrain, migraines and headaches, and that lighting guidance should consider risk management, good practice and minimum recommended levels.

In a workplace, poor lighting can lead to:

eye strain from reading screens or documents in unsuitable conditions;
headaches caused by glare, flicker, excessive brightness or poor contrast;
reduced concentration because employees need to work harder to see clearly;
fatigue, especially where staff spend long periods at computer workstations;
increased mistakes in tasks requiring detail, inspection or reading;
discomfort from reflections on monitors or direct sunlight;
lower productivity in areas where lighting does not match the work being done;
safety risks in corridors, stairs, workshops, storage rooms or plant areas.

Lighting can also affect how employees feel about the workplace. A space that is too dim may feel uncomfortable, dull or tiring. A space that is too bright may feel harsh and stressful. A space with uneven lighting may cause staff to constantly adjust their posture, screen position or working angle to avoid glare and shadows.

For companies, these issues matter because they can affect productivity, staff satisfaction, health and safety, and the overall quality of the working environment.

Why good lighting is important

Good lighting allows employees to work comfortably and accurately without unnecessary strain. It supports visibility, concentration, safety and wellbeing.

In office environments, good lighting is especially important because many employees work with screens for long periods. The aim is not simply to make the office brighter. The aim is to provide the right level of light at the working plane, avoid glare, reduce screen reflections and create a balanced visual environment.

Good workplace lighting helps companies:

improve employee comfort;
reduce complaints about eye strain, glare and headaches;
support productivity and concentration;
improve accuracy in visual tasks;
reduce health and safety risks;
create a more professional workplace environment;
support ergonomic and occupational health assessments;
show that workplace conditions have been properly reviewed.

ADOSH office ergonomics guidance identifies lighting as an important office-environment factor and gives a recommended office lighting range of 30 to 50 foot-candles, equivalent to approximately 300 to 500 lux.

This is why lighting testing is valuable. It gives companies clear data instead of relying only on employee feedback or visual judgement.

Ideal lighting values for workplaces

For office workstations, RMT uses a target range of 300 to 500 lux at the workstation or working plane. This range is suitable for typical office tasks such as computer work, reading, writing and general administration.

The ADOSH office ergonomics guideline recommends 300 to 500 lux for office environments, which provides a useful benchmark for office lighting assessments in the UAE.

As a practical guide:

General office workstations:
300 to 500 lux

Open-plan office areas:
300 to 500 lux, with attention to glare, reflections and uniformity

Meeting rooms:
typically within the office comfort range, but should be assessed based on how the space is used

Reception areas and lobbies:
often lower than workstation lighting, but still need enough light for safe movement and a professional appearance

Detailed inspection or technical work:
may require higher lighting levels depending on the task

Storage areas, corridors and circulation routes:
may require lower levels than desks, but still need sufficient lighting for safe access and movement

The exact lighting requirement depends on the type of work, the age and needs of the occupants, the level of detail involved, the amount of screen work, and whether the space is used for short-term movement or continuous work.

Lighting testing should also consider more than lux readings. The University of Toronto’s lighting ergonomics guidance highlights the importance of suitable lighting for the task, uniform lighting levels, avoiding excessive contrast, using task lighting where needed, and orienting workstations to reduce solar glare.

This is important because two offices can both measure 400 lux but feel completely different. One may have balanced, comfortable lighting. The other may have glare, reflections, shadows or bright sunlight across workstations.

Why lux levels alone are not enough

Lux readings are important, but they are only part of a proper lighting assessment.

A workplace may meet the target lux range and still have poor lighting conditions if employees are affected by glare, contrast, screen reflections or direct sunlight. Likewise, an office may have some areas within the ideal range and other areas below target due to poor lighting distribution.

A proper lighting assessment should consider:

the measured lux level at the working plane;
whether lighting is evenly distributed;
whether there are dark spots or shadowed areas;
whether employees experience glare;
whether monitors reflect windows or light fittings;
whether direct sunlight affects desks;
whether task lighting is needed;
whether the lighting suits the actual work being performed.

This is why RMT’s lighting testing focuses on both measurement and workplace impact. The goal is to help companies understand whether the lighting is genuinely suitable for the people using the space.

How to improve lighting in different situations

Lighting problems can have different causes. The right solution depends on whether the issue is low light, glare, uneven lighting, excessive brightness, screen reflections or poor workstation layout.

If the workplace is too dark

If lighting readings are below the target range, employees may struggle to read documents, see keyboard details, complete paperwork or work comfortably for long periods.

Common improvements include:

increasing general lighting levels;
replacing failed, weak or ageing lamps;
cleaning light fittings and diffusers;
adding task lighting at specific workstations;
reviewing whether furniture or partitions are blocking light;
upgrading old lighting systems to more suitable LED fittings;
adding lighting in areas where staff carry out detailed tasks.

For offices, areas below 300 lux at the working plane should be reviewed, especially if employees are carrying out regular desk-based work.

If there is glare from windows

Glare from windows is common in UAE offices because of strong sunlight and large glazed façades. Even if the lux level is technically acceptable, direct sunlight can make screens difficult to read and cause discomfort.
