Whether you're renovating your space or simply want to improve its lighting, this guide will provide you with the information you need to effectively light your kitchen and optimize brightness.
Understanding Lighting Units of Measurement
Lumens and their role
Lumens (lm) are the unit of measurement that quantifies the luminous flux of a lighting source. They indicate the amount of visible light emitted by a bulb or a luminaire. It is essential to differentiate lumens from watts, because the latter do not measure brightness, but energy consumption.
For example, a 10-watt LED bulb can produce about 800 lumens, while a 60-watt incandescent bulb emits the same amount of light. To properly light your kitchen, it is crucial to know the number of lumens required for each area.
Lux and their relevance
Lux is a unit of illuminance that measures the amount of light received by a surface. For a kitchen, it is generally recommended to have an illuminance level of 300 lux for general lighting , while work areas, such as the countertop and the central island, require around 450 lux.
These levels ensure optimal visual comfort, making kitchen activities easier. Good lighting can also reduce eye fatigue, especially during long meal preparation sessions. By integrating these concepts, you will be able to better assess the power required for suitable lighting.
What lighting power for each area of the kitchen?
General lighting
General lighting, or main lighting, is essential to ensure uniform visibility throughout the kitchen. For a medium-sized kitchen, it is recommended to have total lighting of around 3000 to 5000 lumens, distributed over several light points, such as ceiling lights orLED pendants .
This type of lighting helps to create a pleasant atmosphere and to illuminate the entire room efficiently. It is wise to choose neutral white bulbs to maximize the reflection of light on light surfaces.
Work lighting
Task lighting is essential in areas where specific tasks are performed, such as the worktop and cooking area. For these areas, a lighting power of at least 450 lux is recommended.
It is often advisable to install light fixtures under wall units to direct light directly onto the countertop, reducing shadows. LED spotlights , which provide intense light and low energy consumption, are ideal for this purpose.
Decorative lighting
Decorative lighting aims to create a warm atmosphere in your kitchen. It can be light strips, spotlights or hanging lamps that highlight architectural or decorative elements.
For this type of lighting, it is advisable to use soft light bulbs, which add a touch of elegance and conviviality . By integrating this lighting, you can highlight details such as cabinet fronts or works of art hanging on the wall.
How do I calculate the lighting power needed for my kitchen?
Factors to consider
To calculate the lighting power needed for your kitchen, several factors must be taken into account. The size of the kitchen, expressed in square meters, is decisive in this calculation. The larger your kitchen, the more lumens you will need to ensure adequate lighting.
Ceiling height is also crucial, as a room with high ceilings requires more powerful lighting . In addition, the color of the walls and furniture influences the reflection of light. In general, light colors reflect light better, while dark colors can distort it.
Calculation formulas
To determine the number of lumens needed, a simple formula can be used: multiply the kitchen area in m² by the recommended lux level.
For example, for a 15 m² kitchen with an illumination level of 300 lux, you will need approximately 4500 lumens. By including concrete examples of calculations for different kitchen sizes, you can help readers better visualize their needs.
