Your recommended lux level will appear here once you choose the type of space.

Enter the room size to estimate the total lumen output typically required.

Required lumens are estimated by multiplying the target lux level by the room area. This gives a simple starting point before detailed lighting design.

From Lux Levels to Real-World Specification

Meeting recommended lux levels is only part of the equation. The quality of light distribution, glare control, and long-term performance all play a critical role in whether a scheme actually performs as intended.

That’s why specifiers typically work with luminaires that offer:

  • Verified photometric data
  • Low glare performance (UGR-compliant options)
  • Consistent output over time (L90/B10 standards)
  • Reliable drivers and optical components

 

The products below reflect those principles — designed for projects where lighting needs to perform properly, not just meet minimum values on paper.

Recommended Lux Levels for Office Spaces

Achieving the correct lux level in an office isn’t just about hitting a target number — it’s about how that light is delivered across the space.

Two offices can both measure 500 lux, yet feel completely different depending on glare control, distribution, and the type of luminaires used. That’s why lux should always be considered alongside lighting strategy — not in isolation.

In most modern workplaces, this means combining well-distributed ambient lighting with task-specific illumination using high-performance architectural LED luminaires designed for commercial environments.

Understanding Lux in Real-World Office Design

Lux measures the amount of light reaching a surface — typically the working plane (desk height).

Standards such as EN 12464-1 recommend 300–500 lux for general office work, but this is only part of the picture. What matters more is:

  • Uniformity of light across the workspace
  • Control of glare (UGR ratings)
  • Positioning of luminaires relative to tasks

This is why simply increasing brightness rarely improves a space — it often makes it worse.

Ambient, Task and Accent Lighting (What Actually Delivers Lux)

To achieve consistent and comfortable lux levels, office lighting should be layered into three key types:

Ambient Lighting

This forms the base level of illumination across the entire space. In offices, this is typically delivered using linear LED lighting systems or suspended office luminaires to provide even distribution and minimise shadowing.

Well-designed ambient lighting ensures the overall space meets the required lux level without relying on excessive brightness from individual fittings.

Task Lighting

Task lighting focuses light exactly where it’s needed — usually on desks or workstations.

In commercial settings, this often isn’t a desk lamp. Instead, it’s achieved through carefully positioned suspended linear luminaires above desks or high-performance LED downlights that provide controlled, direct illumination without glare.

This is critical for screen-based work, where poor lighting angles can create reflections and visual discomfort.

Accent Lighting

While less critical for compliance, accent lighting improves visual hierarchy and comfort within the space.

This may include wall-mounted lighting to reduce contrast between surfaces, or feature lighting in breakout areas to create a more balanced environment.

Without this layer, even correctly lit offices can feel flat and fatiguing.

Recommended Lux Levels by Office Area

  • General office areas: 300–500 lux
  • Workstations: 300–500 lux (with strict glare control)
  • Design / technical work: 500–750 lux
  • Meeting rooms: 300–500 lux with flexibility

However, these values only work when paired with the right lighting layout and product specification.

From Lux Calculation to Product Selection

Once you’ve identified the required lux level, the next step is ensuring your lighting scheme can actually achieve it in practice.

This is where specification matters.

For example, open-plan offices aiming for uniform 400–500 lux will typically rely on suspended linear lighting systems to distribute light evenly across desks.

More compact layouts may use a combination of commercial LED downlights and wall-mounted luminaires to fill gaps and maintain consistency.

In all cases, the goal is the same — achieving the required lux level without hotspots, shadows, or glare.

Integrating Emergency Lighting Requirements

Office lighting design doesn’t stop at normal operation. Emergency lighting must also be considered alongside lux levels.

Escape routes, open areas, and high-risk zones all have minimum illumination requirements, which are typically delivered using dedicated LED emergency lighting systems.

These should be integrated into the overall layout rather than treated as an afterthought.

Common Mistakes That Undermine Lux Levels

  • Over-lighting instead of improving distribution
  • Ignoring glare (UGR) in screen-heavy environments
  • Poor luminaire positioning relative to desks
  • Inconsistent fittings across the same workspace

Most lighting issues come from layout and specification — not insufficient lumen output.

Why This Matters for Workplace Performance

Lighting directly affects how people feel and perform.

Well-designed lighting reduces fatigue, improves focus, and creates a more comfortable working environment.

Poor lighting — even when technically “bright enough” — leads to eye strain, headaches, and reduced productivity over time.

Many organisations are now also prioritising sustainable, recyclable luminaires to reduce lifecycle impact while maintaining high performance.

Lux Level FAQ

Typical office lighting levels are based on BS EN 12464-1, which recommends around 300–500 lux for general office work.

Tasks requiring greater visual focus, such as detailed drawing or technical work, may require higher levels.

The exact requirement depends on the layout, task type and visual comfort targets such as glare control (UGR).

Warehouse lighting requirements vary depending on the activity within the space.

General storage areas typically require around 100–200 lux, while picking, packing or inspection zones may require 300 lux or more. Higher lux levels may also be needed in areas where accuracy and safety are critical.

Lumens measure the total amount of light emitted by a light source, while lux measures how much of that light reaches a surface.

In simple terms, lumens describe output, whereas lux describes illumination at a specific point. This is why lux is used when planning lighting levels within a space.

EN 12464-1 provides guidance on lighting levels for indoor workplaces, with recommended lux levels depending on the task and environment. For example, offices typically require 300–500 lux, while circulation areas may require lower levels. The standard also considers factors such as glare, uniformity and visual comfort.
