The beam angle determines how wide or narrow a lamp scatters light on a surface, and is expressed in degrees (°).

This indicates which type of light source in terms of shape and size is compatible with this fixture. For example, the A series indicates a classic light source shape, the T series indicates tubular lamps and the G series indicates spherical lamps. Read more...

CRI stands for Colour Rendering Index. It is a measure of how vividly colours are rendered in a room. A higher CRI value gives a more accurate rendering. Read more.

This is the highest possible amount of visible light the lamp produces (in non-dimmed mode). Using this value, you can determine the amount of light and the number of lamps in a project or installation.

The appliance class indicates the extent to which the appliance protects against electric shock. The degree of insulation is shown according to ascending protection values "I", "II" and "III". The higher the device class, the higher the degree of protection.

The IP rating is a standardised rating system that indicates the degree of protection the device provides against the ingress of solid objects (such as dust) and liquids (such as water). For example, an IP65-rated device has good protection against solids (IP6X) and is resistant to spray water (IPX5). The higher the IP rating, the better protected the device is. "Read more.
