Lumen

Lumen describes the amount of light emitted by a light source. More lumens mean more brightness in the room.

lux

Lux indicates how much light actually reaches a surface. A desk, for example, needs more brightness than a cozy seating area.

Kelvin

Kelvin represents the color temperature of light. Warm light starts at around 2700 K, neutral light is around 4000 K, and very cool light, at 5000 K and above, resembles daylight. The color temperature of light significantly influences the atmosphere in a room.

CRI or Ra

The CRI value indicates how natural colors appear under a light source. A high value ensures that skin tones, fabrics, and materials look realistic and clear.

Beam angle

The beam angle determines whether the light appears focused or spreads widely throughout the room. A narrow beam angle creates accent lighting, while a wide beam angle provides soft, generous illumination.

Half-angle of scattering

The half-angle of dispersion shows how gently the light decreases towards the edges. A large angle ensures even light distribution. A small angle creates focused points of light.

reflection

Light surfaces reflect light and make rooms appear brighter. Dark surfaces absorb light and create a calmer atmosphere. The materials in a room therefore strongly influence the way light is perceived.

Colors in the room

Light colors bring more light back into the room and create an open and bright atmosphere. Dark colors absorb light and create a more atmospheric environment. Therefore, color selection plays an important role in the overall effect of the lighting.
