Task lighting is a type of focused illumination designed to provide bright and targeted light for specific activities. It is often used in situations where good visibility is crucial for performing a task efficiently and comfortably. Task lighting is distinct from general lighting, which aims to illuminate an entire room with a more ambient and even glow.
Key Characteristics:
- Focused Illumination: Task lighting concentrates light on a specific area or workspace, minimizing shadows and ensuring good visibility for detailed tasks.
- Increased Visibility: By providing targeted light, task lighting reduces eye strain and improves visual clarity, allowing users to perform tasks more effectively and with less fatigue.
- Adjustable: Many task lights are adjustable in terms of direction, intensity, and sometimes even color temperature, allowing users to customize the lighting to their specific needs and preferences.
- Variety of Applications: Task lighting is used in various settings, including homes, offices, workshops, and studios.
Common Applications:
- Home: Task lighting is often used in kitchens for food preparation, above desks for reading and writing, near bathroom mirrors for grooming, and in task areas for hobbies like sewing or crafting.
- Office: Task lighting can illuminate individual workstations, desks, and conference tables, supporting computer work, reading documents, and presentations.
- Workspaces: Task lighting is essential in workshops, studios, and garages, providing focused light for detailed work on projects like repairs, painting, or crafting.
- Commercial Settings: Task lighting can be used in retail stores to highlight specific products or in restaurants to create a more intimate atmosphere at tables.
Benefits of Task Lighting:
- Improved Visual Acuity: Provides adequate lighting for detailed tasks, reducing eye strain and improving accuracy.
- Enhanced Comfort: Reduces fatigue by minimizing eye strain and creating a more comfortable work environment.
- Increased Productivity: Better visibility can lead to improved efficiency and focus when performing tasks.
- Flexibility and Customization: Adjustable task lights allow users to tailor the lighting to their specific needs.
- Energy Efficiency: Focused lighting can be more energy-efficient compared to illuminating an entire room with general lighting.
Choosing Task Lighting:
- Consider the task: The type of task will dictate the required light intensity and color temperature.
- Placement: Position the light to illuminate the work area effectively without creating glare.
- Adjustability: Choose a light that can be adjusted in terms of direction and intensity for optimal customization.
- Style and Aesthetics: Select a task light that complements the overall design and style of the space.

Often task lighting refers to increasing illuminance to better accomplish a specific activity. However, the illuminance level is not the only factor governing visibility. Contrast is also important, and a poorly positioned light source may cause contrast reduction, resulting in loss of visibility. The most important purpose of task lighting in the office is not increasing illuminance, but improving contrast. General lighting can be reduced because task lighting provides focused light where needed.
Different strategies for task lighting exist. The three main approaches are:
- Localized average lighting, where a lamp supplies both ambient light and task light
- Freely adjustable task light such as a gooseneck, balanced-arm lamp, or swing-arm light.
- Asymmetric task light, where the lamp is placed at the side of the work area
There are also other approaches to task lighting, for example under-shelf luminaires.
Other instances of task lighting are in machinery, where a specific work area needs illumination, and in workshops, where a task light may illuminate the actual working area. Special instances of task lighting are examination and operation lights for medicine and surgery, as well as the dentist's lamp. Task lamps are also used for many home tasks such as sewing, reading, small repairs, model construction, crafts, writing, and many other activities. The actual task may range from very small up to about as far as you may reach with your hands or available tools. Lighting of larger areas is beyond the scope of task lighting.
