Lumens (Lm) are the unit of measurement for light flux, indicating the intensity and brightness of light emitted by a lamp or light fixture. Based on their quantity, you can choose a light fixture that will properly illuminate the entire room.

How to choose the right number of lumens in a light fixture?

450-800 Lm are used for decorative lighting, table lamps, bedside lamps. Light fixtures with up to 800 Lm brightness are suitable for creating a cozy environment.
800-1100 Lm are used for small rooms (bedrooms, hallways).
1100-1600 Lm are used for medium-sized spaces such as dining rooms, kitchens, bathrooms, and children's rooms.
1600-3000 Lm are used for large rooms (shopping malls, entire 11-18 square meter rooms).
Light fixtures with more than 3000 Lm emit very bright and intense light. They are used in workshops, garages, and industrial spaces.
To accurately calculate the required number of lumens for a room, use the formula:

Lm = 150 lx * 4π * (distance in meters to the surface)²
