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

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 value indicates the colour temperature of the light produced, expressed in Kelvin (K). The lower the Kelvin value, the warmer the light feels. In turn, a bulb with a higher Kelvin value gives a colder impression. For example, the warm white glow of an incandescent lamp has a Kelvin value of 2700K.

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 specific type or hue of light emitted by a light source, such as a bulb or LED. Different light colour types can have varying effects on the appearance of objects and people in a given environment. For example, a warmer light colour type may create a cosy and inviting atmosphere, while a cooler light colour type may appear more clinical or energising. When selecting light bulbs or fixtures, be sure to consider the desired mood or ambiance you wish to create, as well as any functional requirements, such as task lighting or colour accuracy.

This indicates whether the light source is included or not. If the lamp(s) are not included, you will find the matching lamp in accessories.

This is the electrical part of the lamp that makes contact with the light source. The type of fitting determines which type of light source you can use. Manufacturers always indicate the maximum power the fitting can handle. It is important that the total consumption of the light source does not exceed the maximum power of the fitting.

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.

This refers to the expected life of the light source and is expressed in total burning hours, sometimes supplemented by "switch cycles". This indicates how many times you can switch the lamp on and off before it needs replacing.

The maximum allowable electrical consumption of the product under normal conditions, expressed in watts (W).

This indicates which electrical connection the product operates on. A lot of lamps can simply be connected to the mains voltage coming from the sockets in your home (230V). But LED lights do not always work on the mains voltage supplied at home. Just think of LED strips that often work on 24Vdc or LEDs that need to be fed with a constant current. It is important to provide the right electrical connection, otherwise your lighting may break down.

This indicates whether the brightness of this product can be adjusted using a dimmer. This does not mean that a dimmer is included.

This is the way the product is installed, on or in a surface. With surface mounting, you install the lighting directly against a surface. Recessed lighting is installed in a surface, so the lighting does not protrude above the installation surface. Sometimes we speak of semi-recessed lights. These lamps are installed in a surface, but part of the fixture protrudes above the installation surface.

Indicates the type of energy source used to operate the lighting, e.g. mains power, battery or solar.

This indicates the type of springs of the lamp. The spring type is determined according to the surface in which recessed lights are installed. Wire springs are used for hollow walls such as suspended plaster ceilings. Blade springs are used for solid walls such as vaulted ceilings. In many cases, blade springs can be used for both solid and hollow walls. Manufacturers often designate wire springs as S1 and use the designation S2 for blade springs.

This tells you whether the manufacturer allows the product to be installed outdoors. Lighting for outdoor use has better resistance to elements such as rain, heat, UV or even corrosion. These fixtures always have a higher IP rating to prevent water damage.
