In today’s workplace, lighting is far more than a convenience. It plays a major role in productivity, comfort and overall wellbeing.

If an office is too dim, staff may experience fatigue and poor concentration. If it is too bright or badly controlled, glare and discomfort can quickly become a problem.

Getting the balance right helps create a healthier, more efficient place to work.

Recommended Office Lighting Levels

Lighting is often measured in lux, which is the amount of light falling onto a surface. For many office environments, a range of 300 to 500 lux is commonly recommended.

This range supports visibility, comfort and day-to-day working tasks without excessive brightness.

300 Lux: Suitable for General Areas

At the lower end of the range, 300 lux can work well in circulation spaces and general-use areas where detailed tasks are not the main focus.

• Corridors
• Breakout zones
• Reception waiting areas
• Storage rooms

It provides clear visibility while avoiding unnecessary energy use.

500 Lux: Better for Focused Work

For tasks requiring concentration and visual accuracy, brighter lighting closer to 500 lux is often the better choice.

Why Proper Lighting Matters

• Improves concentration
• Reduces visual fatigue
• Supports mood and wellbeing
• Creates a more professional environment
• Improves task accuracy
• Can lower energy costs with efficient systems

Modern LED systems, dimming controls and daylight-responsive lighting can help offices maintain comfort while reducing waste.
