Lumen (lm) is a unit of measurement used to evaluate the amount of light emitted by a light source. In other words, it measures the total luminance produced by the lamp, which is the amount of light that the human eye can perceive.

1. Lumen vs Watt: What's the Difference?

While watt (W) measures the energy consumption of a light source, lumen (lm) measures the actual brightness perceived by the human eye.
The more lumens a lamp emits, the brighter it appears, regardless of its power consumption in watts.

2. How to Choose the Right Brightness?

When choosing a light fixture, it’s important to consider the number of lumens based on the room's usage:

• For living rooms and bedrooms: A lighting level of 100 to 300 lumens/m² is often sufficient to create a soft and pleasant atmosphere.
• For kitchens and offices: It is recommended to choose fixtures that provide 300 to 500 lumens/m² to ensure good visibility.
• For technical areas and workshops: The required lighting can reach up to 500 to 700 lumens/m² to ensure optimal lighting.

3. Lumen and Color Temperature: How to Combine Them Correctly?

Lumen determines the brightness of the light, but it does not define the color of that light. The color is measured in Kelvin (K) and ranges from cool light (bluish-white) to warm light (yellowish-white).

• Warm light (2700K-3000K): Ideal for living rooms and bedrooms, creating a cozy and relaxing atmosphere.
• Neutral light (4000K-4500K): Perfect for kitchens and offices, promoting concentration.
• Cool light (6000K-6500K): Often used in work environments such as workshops and garages.

4. Why Choose LED Lamps?

LED lamps are extremely efficient because they offer high brightness with low energy consumption. They also have a long lifespan and produce less heat, making them ideal for long-term use.

Conclusion

Lumen (lm) is a key factor in choosing the lighting that best suits your needs. Depending on the required brightness for each room in your home, you can optimize your comfort and create the perfect atmosphere for each space.
