Lux Light Level Testing for Offices & Commercial Spaces

Regular lux light level testing is now recognised as best practice for offices, schools and commercial environments. This process measures illumination levels (lux) to assess how much light people experience in spaces where they work, relax, or shop.

Why Lux Light Level Testing Matters
Health and safety regulations require lighting to be appropriate for the tasks being undertaken, ensuring environments remain safe and compliant. However, effective lighting goes beyond compliance alone. Poorly designed lighting can negatively impact health and wellbeing, leading to eye strain, headaches, fatigue, reduced concentration, and an increased risk of accidents.

 

Recommended Lux Levels for Offices and Commercial Spaces

Industry guidelines recommend target lux levels for different environments, but these figures should be treated as benchmarks rather than fixed rules. People perceive light differently, and what feels comfortable for one person may be unsuitable for another. This is particularly relevant for individuals with reduced or partial sight, who often require higher illumination levels to work safely and comfortably.
When determining appropriate lighting levels, it is important to consider how the space supports productivity, visual comfort, and overall wellbeing.

 

Limitations of Software-Based Lighting Calculations

In the M&E and lighting design sectors, computer-based lighting calculations are often used to predict lux levels for specified fittings. While useful at the design stage, our experience shows that these simulations can only provide approximate results and may not accurately reflect real-world performance once installed.
Factors such as surface finishes, room geometry, glare, and installation conditions can all influence the actual delivered light levels.
