Optimal Workplace Lighting: Your Guide for 2024

Good lighting at the workplace is more than just a bright lamp. Optimal lighting is a combination of bright general lighting, a targeted lamp for your tasks, and as much daylight as possible. The crucial factor is the mix of the right brightness (measured in lux) and the appropriate light color (in Kelvin), tailored to your activity. Only then can concentration and well-being be maintained.

Why the right lighting at the workplace is crucial

Lighting influences your performance more directly than you think. Incorrect or insufficient light is a real burden on body and mind.

If it's too dark or a lamp glares, your eyes have to work extra hard. The result is tired, dry eyes and often headaches that impair your concentration.

The connection between light and performance

Well-planned lighting creates an atmosphere where you can stay focused and work productively. Good light keeps you awake and supports your biorhythm.

The positive effects are clear:

• Increased concentration: Sufficiently bright, glare-free light helps you stay focused.
• Less fatigue: Your eyes are noticeably relieved.
• Lower error rate: Those who clearly see documents and the screen make fewer careless mistakes.
• Better well-being: A pleasant lighting atmosphere improves your mood.

Optimal lighting at the workplace is an ergonomic necessity. It is a direct investment in your health and performance.

The gap between aspiration and reality

Awareness of good light exists. A Forsa survey showed that 94 percent of respondents consider good light important. However, the reality in offices often looks different. More than half of companies offer hardly any individually adjustable lighting solutions. Employees often prefer an illuminance of 800 lux or more, although the standard only requires 500 lux. You can find more about this in the findings on age-appropriate lighting on i-magazin.com.

This guide gives you the knowledge to close this gap. I will show you how to create optimal workplace lighting that meets ergonomic standards and suits you.

Choosing the right light sources for your desk

A single ceiling light alone does not create optimal lighting at the workplace. A well-thought-out lighting concept is necessary. In practice, a mix of three different light sources has proven effective.

The basis is general lighting. It ensures that the entire room is evenly illuminated. This is usually achieved with ceiling lights or indirect light sources.

The three pillars of workplace lighting

A good lighting concept is built on these three elements:

• General lighting (Ambient Lighting): It creates a general brightness and avoids strong contrasts between your bright screen and a dark environment.
• Task lighting: A good desk lamp provides targeted light exactly where you need it for your documents or other activities.
• Accent lighting: This optional lighting specifically highlights shelves or pictures and contributes to the atmosphere.

When choosing a desk lamp, pay attention to practical features such as dimmability and a flexibly adjustable arm. This allows you to adjust brightness and alignment at any time. In our guide, you can find out how to find the right desk lamp.

The right bulb and the appropriate color temperature

LED technology has become established for light sources. LEDs are more energy-efficient, longer-lasting, and provide stable light quality without flickering.

The color temperature, measured in Kelvin (K), determines whether the light appears warm or cool:

Color Temperature	Description	Effect and Application
Below 3,300 K	Warm White	Creates a relaxed atmosphere for creative breaks.
3,300 to 5,300 K	Neutral White	Promotes a factual, concentrated work environment. Ideal for most office activities.
Above 5,300 K	Daylight White	Has a stimulating and activating effect. Ideal for video conferences or detail-oriented work.

Use different color temperatures specifically. Start the day with neutral white light and switch to daylight white light for maximum concentration.

By consciously controlling the light, you support your biorhythm and can steer your productivity.

Positioning your lighting correctly and avoiding glare

A high-quality lamp alone does not create optimal lighting at the workplace. Incorrectly positioned, it can do more harm than good. The biggest problem is glare. It leads to tired eyes and declining concentration.

Direct glare comes from the light source directly into the eye. Indirect glare arises from reflections on smooth surfaces like your monitor. Both types of glare can be avoided with simple adjustments.

The correct position of your desk lamp

The alignment of your desk lamp is crucial to avoid shadows and reflections.

• For right-handers: Position your desk lamp on the left side. This way, your writing hand won't cast a shadow.
• For left-handers: Place the lamp on the right side, so your left hand doesn't cast shadows.

The lamp head should be adjusted so that it does not shine directly at you. Direct it towards your keyboard or the work area in front of you. The light should hit the tabletop below your eye level.

A simple practical test: Sit normally at your workstation. Can you look directly into the light source? Then the lamp is incorrectly adjusted. The lampshade should always completely cover the light source from your sitting position.

Dealing with daylight and indirect glare

Daylight is the best light source, but it can also be a source of glare. The orientation of your desk to the window is therefore crucial.

Place your desk sideways to the window. This way, you use natural light without being blinded or having reflections on the monitor. If you sit directly in front of the window or with your back to it, your eyes will constantly have to adjust to extreme differences in brightness.

Here are a few quick solutions:

• Use blinds or roller shutters: These allow you to control strong sunlight.
• Use a matte desk pad: It absorbs reflections from the table surface.
• Adjust monitor correctly: Tilt or rotate it slightly until no more reflections are visible.

A well-thought-out arrangement of your workstation and light sources costs nothing but has a great impact on your well-being.

Understanding legal requirements and recommended lux values

Optimal lighting at the workplace is also a matter of legal requirements. These rules are based on ergonomic findings and are intended to ensure a safe working environment.

In Germany, the Workplace Ordinance (ArbStättV) and the European standard DIN EN 12464-1 are decisive. They define minimum requirements for brightness, uniformity, and glare-free conditions.

What do lux values mean in practice?

The lux value (lx) describes how much light falls on a surface, for example, on your desk. The higher the value, the brighter the area.

For general office activities, regulations prescribe a minimum illuminance of 500 lux on the work surface. For finer tasks such as technical drawing, the recommended value increases to 750 to 1,000 lux.

These figures are based on studies. Appropriate lighting improves visual performance, reduces fatigue, and lowers the error rate.

Recommended illuminance (lux) for various activities

This table shows the minimum values recommended according to DIN EN 12464-1.

Activity Area	Task	Recommended Illuminance (Lux)
General Office Areas	Writing, Reading, Data Processing	500 lx
Technical Offices	Technical Drawing, CAD Work	750 lx
Precision Mechanics & Electronics	Assembly of Fine Components, Inspection Work	1,000 lx
Graphic Design	Color Matching, Checking Print Templates	1,500 lx

It is worthwhile to consider your own activity and adapt the lighting accordingly.

More than just brightness: The color rendering index

The quality of light is also crucial. The color rendering index (CRI or Ra) indicates how faithfully colors appear under an artificial light source compared to sunlight (CRI of 100).

• For office workplaces, a CRI value of over 80 is required.
• This ensures that colors do not appear distorted.
• Lamps with a CRI of over 90 offer excellent color rendering.

When selecting your lamps, pay attention to lux, color temperature, and the CRI value. Learn more about the legal regulations for workplace lighting and how to implement them.

How light demonstrably influences your productivity

Optimal lighting at the workplace is a scientifically proven investment in your concentration and performance. The connection between light quality, productivity, and error rate has been clearly demonstrated.

Well-planned light improves visual ergonomics, which means your eyes tire less quickly. This alone ensures a longer concentration span.

The direct influence of brightness on performance

Numerous studies show: The higher the illuminance, the better the work performance. If the brightness is above the minimum value of 500 lux, people can complete tasks faster and more precisely. The error rate decreases because details are clearer to see.

This is particularly relevant for anyone who works a lot with numbers, texts, or graphics. Bright and uniform illumination increases your work quality.

Targeted improvement of lighting conditions is an effective method to increase productivity in the short term.

Human Centric Lighting as the next step

An advanced approach is Human Centric Lighting (HCL). This concept adapts to the natural course of the day and supports the biorhythm.

Here's how an HCL system works:

• In the morning: The light has a high blue component and high intensity. This has an activating effect and helps you start the day awake.
• In the afternoon: The light color becomes warmer and the intensity decreases. This signals to the body the approaching end of the day.
• In the evening: Warm white, dimmed light promotes recovery and prepares for sleep.

This dynamic adjustment stabilizes our internal clock. This improves concentration during the day and increases overall well-being.

Measurable success through better light

Scientific studies show that lighting concepts like HCL can increase productivity by up to 4.5 percent. At the same time, errors can be reduced by 1 to 2 percent. As the Federal Institute for Occupational Safety and Health confirms, employee satisfaction also increases.

These findings are just as valuable in the home office as they are for large offices. In our article, learn how to use the right light at the workplace to combat fatigue.

Practical checklist for your workplace lighting

With this checklist, you can analyze your current lighting situation and make targeted improvements.

The basics: What stands out immediately

• Check illuminance: Download a light meter app and hold your smartphone on the work surface. The value should be at least 500 lux.
• Identify glare sources: Sit at your workstation. Is a lamp or window reflected in the monitor? Eliminate all direct and indirect glare.
• Check for shadows: As a right-hander, the desk lamp should come from the left; as a left-hander, from the right. This prevents annoying shadows.
• Optimize daylight: Your desk should be positioned sideways to the window. This way, you use natural light without glare.

Fine-tuning for more productivity

Once the basics are right, it's time for the details.

Good lighting is dynamic. Adjust it to your needs throughout the day.

• Adjust color temperature: For concentrated work, neutral to daylight white light is ideal (4,000 to 6,500 Kelvin). Warmer light is suitable for creative breaks.
• Balance contrasts: Always turn on general room lighting as well to avoid harsh light-dark contrasts. This relieves your eyes.

Frequently asked questions about workplace lighting

Here you will find quick answers to typical questions about workplace lighting.

What is the difference between lux and lumen?

Lumen is the total amount of light emitted by a lamp. Lux measures how much of that light actually falls on a surface like your desk.

For the workplace, the lux value is crucial because it describes the brightness at your workstation.

Which lamp is suitable for a two-monitor setup?

For a two-monitor setup, wide, elongated lamps such as monitor lights or screen bars are the best choice. They illuminate the work surface evenly without shining on the screens or causing reflections.

A high positioning of the lamp prevents the monitors from casting shadows.

How do I recognize disturbing light flickering?

Flickering is often not visible to the naked eye but can lead to headaches.

• The smartphone camera test: Open your phone's camera app.
• Look at the screen: Point the camera at the light source. If you see dark streaks moving across the image, the lamp is flickering.

This is often due to fluctuations in the power supply of inexpensive LED luminaires. High-quality LEDs with stable drivers minimize this effect.

How do I avoid reflective glare on my glossy desk?

High-gloss tabletops can reflect strongly. The simplest solution is a matte desk pad. It absorbs light instead of reflecting it.

Alternatively, you can position your desk lamp so that the light hits the surface from a different angle.
