Conversion of lighting units

Lighting Units Conversion and the Importance of Lumens to Lux

Lighting is ubiquitous and plays a critical role in everything from our health and well-being to the efficiency and aesthetics of our homes and workspaces. But do you know how lighting is measured, and what these measurements mean?

What is Lighting and How Is It Measured?

Lighting, or photometric quantity, is a measure of the intensity of light perceived by the human eye. The most common units used are lux (lx), which expresses the intensity of illumination, or lumen (lm), which expresses the amount of luminous flux.

The Importance of Lighting Unit Conversion

Different situations and applications require different levels of lighting. For example, office workspaces need a different type of lighting than a home environment or an art gallery. Proper lighting unit conversion will help you achieve the optimal level of light for your specific needs.

Practical Applications in Everyday Life

What is the ideal number of lux for reading? What is the difference between lighting for a work surface and a relaxation area in the living room? Let’s take a look at some practical examples of lighting for different environments.

Tip: Try smart light bulbs from the BrainMarket.cz e-shop. Automatic light bulb dimming scenarios using the Tuya smart app (both Android and iOS).

Bedroom:

• Ambient lighting: 100-300 lux. Use dimmable ceiling fixtures to create a relaxing atmosphere.
• Reading lights: 400-500 lux. Wall sconces or table lamps with adjustable heads are ideal for reading or other activities requiring more light.

Living room:

• Ambient lighting: 150-300 lux. Ceiling fixtures or pendant lights provide basic lighting for general activities.
• Task lighting: 400-600 lux. Use focused lights or floor lamps for activities such as reading or crafts.
• Accent lighting: 200-300 lux. Accent lights can highlight paintings, shelves, or architectural features.

Office:

• Ambient lighting: 300-500 lux. A quality ceiling light that provides adequate lighting for general orientation in the room.
• Task lighting: 700-800 lux. A desk lamp with an adjustable neck to focus light directly on the work surface for activities requiring concentration, such as writing or drawing.

Kitchen:

• Ambient lighting: 300-400 lux. Ceiling or pendant lights evenly distributed throughout the room.
• Task lighting: 700-800 lux. Under-cabinet lighting or pendant lights over a kitchen island for food preparation and cooking.

Bathroom:

• Ambient lighting: 100-200 lux. Ceiling lights for general lighting.
• Task lighting at the mirror: 500-600 lux. Lights placed on either side of the mirror or above it to illuminate the face without shadows, ideal for shaving or makeup.

Keep in mind that these values are approximate and the optimal level of lighting may vary depending on the specific needs of the users and the characteristics of the room, such as the color of the walls, furniture, and natural light.
