What is light intensity and how does it affect lighting in the home
Shari
When we talk about home lighting, many of us first think about the design of the lighting fixtures or the type of bulbs used. However, an essential aspect that makes the difference between a welcoming space and a boring one is the intensity of the light. In short, light intensity is the "strength" or amount of light emitted by a source and has a direct impact on how we perceive a space and how we feel in it.
Consider a dimly lit room: it can look dreary and unfriendly, even if it's beautifully decorated. Conversely, too bright light can create the feeling of discomfort or lack of privacy. Therefore, the light intensity must be adapted to each room and activity: a warm and moderate light in the living room for relaxation, a higher intensity in the kitchen for good visibility or a balanced lighting in the office to stimulate concentration.
Understanding the intensity of light and how you can control it gives you the freedom to transform your home into a harmonious and functional space. The right choice is not only a matter of aesthetics, but also of comfort, efficiency and well-being.
What does light intensity mean?
Light intensity shows how much light reaches a certain area, measured in lux (lx). The light source, such as a light bulb or a ceiling light, emits a luminous flux expressed in lumens (lm). The higher the luminous flux, the more efficiently the source can cover a space.
There are several types of bulbs: an 800 lumen bulb will light differently in a table lamp than a spot mounted in the ceiling and aimed at the desk. In addition, the way you perceive light also depends on the color temperature measured in Kelvin (K) – warm light (below 3300 K) gives an intimate, relaxing effect, and cool light (above 5000 K) helps concentration.
The difference between luminous flux, luxury and intensity
When deciding how to light a room, you quickly notice that these three notions influence the final result, refined over years of evolution of lighting fixtures.
| Term | Definition |
|---|---|
| Luminous flux (lumens) | The total light emitted by the source. |
| Luxury | How much light reaches the surface you are actually using. |
| Light intensity | It explains how concentrated or spread the light is in a certain area. |

What influences the intensity of light at home
Several factors contribute to how you perceive light in a room:
- Source type: LEDs save energy and last longer, filament bulbs generate warm light but consume more current.
- Positioning: A desk lamp makes the difference between a dimly lit area and one suitable for reading or working.
- number lighting fixtures: If you use several low power lights you can place them in key points to avoid dark areas.
- Body design: A Brigitte remote control LED chandelier with 6 circles, dimmable easily adjusts the light between warm, cool and neutral, suitable for relaxing evenings or activities that involve mindfulness.
It is recommended to choose a source with intensity control if you want to adapt the atmosphere quickly according to the activity.
How to choose the right level of light for each room
Each room requires a different intensity of light. For good results, aim for the following light values for each space (values are lumens per square meter):
- Kitchen: 75–100 lm/sq – ceiling or spotlights provide a clear light for cooking.
- Office: 500–1000 lm/sq – Adjustable lamp or spot for excellent vision.
- Living room: 200–400 lm/m2 – Combine ceiling lights with lamps and Wall for a pleasant light.
- Bathroom: 250–400 lm/sq – Use cool light around the mirror for details.
- Bedroom: 100–300 lm/m2 – Choose sources with warm light for comfort at the end of the day.
In open spaces ("open space"), combine general and spot lighting - such as commercials or LED strips. In the case of accent walls, a strategically placed light fixture brings out the texture or color.
How light affects mood and productivity
The right lighting supports the desired atmosphere. A diffused, warm light relaxes the senses after a busy day. A cool, focused light maintains focus during working hours. You can add discreet projectors to hallways or stairwells for increased safety – explore the collection of outdoor projectors as an example.
In the evening, dim the lights in the bedroom - thus supporting the body's sleep rhythm (circadian rhythm). For example, an adjustable lamp provides a gentle transition to the hours of rest.
Tips for installing and maintaining lighting fixtures
Modern solutions come with clear instructions, but you can apply these basic recommendations for lasting results:
- Read the specs for luminous flux (lumens), not just wattage (watts).
- Check the socket type for compatibility (E27, GU10, etc.).
- Mount the fixtures according to the manufacturer's recommendations.
- Periodically clean the light fixtures with a dry cloth to maintain efficiency and avoid dust build-up.
- Replaces classic light bulbs with LEDs for low cost and extended life.
- tested LED spotlights if you want economy and easy long-term maintenance.
By carefully selecting sources, you can also reduce the risk of overheating or accidents.
Ideas for lighting adapted to your taste
Create an environment that represents you by adapting the sources to the style and needs of your home. If you have a modern style, the light accents integrated in the furniture or the use of a smart system can make your space more efficient. In classic settings, chandeliers or lamps with lampshades complete the visual warming. In minimalist settings, discrete spotlights provide the necessary light without visually cluttering the room.
It emphasizes personalization and adapting lighting to daily activities. Use dimmable sources, combine direct and ambient light, and clean fixtures regularly to keep them efficient.

Frequently Asked Questions
What is light intensity and why is it important?
Light intensity refers to the "strength" or amount of light in a space and is essential to creating a pleasant and functional atmosphere. An inappropriate intensity can make a room seem sad and unwelcoming, or, on the contrary, create visual discomfort and a feeling of fatigue.
What is the difference between luminous flux, lux and luminous intensity?
The luminous flux, expressed in lumens, represents the total light emitted by the source. Lux measures how much light actually reaches the illuminated surface, and luminous intensity shows how concentrated or spread the light is in a certain area.
What light intensity should I choose for each room?
The ideal intensity varies according to the activity carried out in each space. For the kitchen, 75–100 lm/m2 is recommended, while for the office, the values are much higher, 500–1000 lm/m2. In the living room, you can choose a value between 200–400 lm/m2, while in the bathroom and bedroom, the values can be adapted, reaching 250–400 lm/m2 and 100–300 lm/m2, respectively, to ensure optimal comfort.
