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

3 main types of white light:
Warm white (2700 - 3000 K)
Neutral white / daylight (4000 - 4500 K)
Cool white (5000 - 6500 K)
How to choose the right light color temperature:2700 - 3000K creates a cozy atmosphere in a room. Used in spas, hotel entrances, living rooms, and bedrooms.
4000 - 4500K is used in commercial, retail, office spaces, garages, medical buildings, as well as bathrooms, kitchens, and workrooms.
5000 - 6500K is suitable for lighting workshops, operating rooms, or other areas where attention to detail is important. Also suitable for outdoor lighting, modern interiors, and their accents.
