Our all-in warranty is fully included in the product price and covers both hidden defects and technical defects of the product that occurred before delivery. The warranty period differs per product and ranges from 1 year to a maximum of 7 years.

Lighting with a built-in emergency lighting unit (battery) continues to burn for a certain time if the power fails.

The technology indicates the operating base of a light source. The most well-known and energy-efficient example is LED. Other techniques include Halogen, gas discharge, TL (fluorescent) and the light bulb.

This indicates which wattage of your old/conventional lighting is replaced by this LED product.

The wattage indicates how much energy a light source consumes. With LED lighting, the wattage is considerably lower than with conventional lighting. LED lamps with a higher wattage generally also have a higher light intensity (number of lumens).

Lighting with a voltage of 220-240 Volt can be connected directly to the mains. Lighting with a different mains voltage (12 Volt and 24 Volt) requires an (electronic) transformer.

When you dim lights, the full power does not have to be used. You therefore save extra on energy costs. Dimmable lamps can also be used to create an extra cosy atmosphere. Keep in mind that you need a LED dimmer to dim LED lights.

The colour code is a combination of colour rendering (CRI) and light colour (Kelvin). The first number indicates the colour rendering (1 = very poor colour rendering, 9 = maximum colour fastness). The second and third number contains the light colour. Example: the colour code 830 consists of good colour rendering (8) and warm white light (3000K).

Colour rendering is also known as Colour Rendering Index (CRI) and indicates the extent to which a light source reproduces colours, compared to the actual colours in daylight. Products with a good (80-89 Ra) or excellent (90-99 Ra) colour rendering show minimal deviations in the colour spectrum.

The light color indicates the color of the light emitted: white, colored, or UV. For many products in our assortment, the light is white, available in a range from very warm white to daylight white (expressed in Kelvin). With colored light, you have two options: 1. A single fixed color, such as red or green. 2. RGBW, which means you can adjust the light color at any time: white or colored.

The colour control type tells you in which way you can regulate the colour of the light. You have the following options: 1. Single colour: This light has one fixed light colour. You cannot change it. 2. CCT: You choose from 2 or 3 fixed colours via a switch, such as warm white or cool white. 3. Tunable white: The white light can take any values in the listed Kelvin scale, for instance 2200K up to 6500K. 4. Dim to warm: Dimming makes the light warmer (more yellow). The more you dim, the warmer the colour. 5. RGB: You can set the light to almost any colour. From red to blue, you fill it in completely as you wish. By choosing your preferred light colour options, you are one step closer to the right light product.

A beam angle indicates the angle of the light beam coming from a light source. The smaller the radiation angle in degrees (D), the narrower the beam angle.

The number of lumens (lm) is the light output of a light source. The higher the number of lumens, the more light the light source emits. The wattage and the number of lumens are not connected to each other. An LED lamp with a low wattage can have a higher number of lumens than a conventional lamp with a high wattage.

The Luminous Efficacy (lm/W) indicates how efficiently a light source uses energy. We divide the number of lumens by the wattage. The higher the number, the more efficient a product is in terms of energy consumption. LED lighting has a considerably higher lumen/Watt ratio than conventional lighting.

The power factor indicates how efficiently a luminaire uses electricity. The rule is: the higher the power factor, the more efficient the power consumption. A product with a high power factor (0.85 - 0.95) is also the safest. This is because the amount of unnecessary power consumption (blind current) is very limited.

The Unified Glare Rating (UGR) indicates the extent to which the light of a product is blinding. This value differs per application and must comply with European standards (EN 12464-1). A low UGR value stands for a low glare factor. For offices and schools lighting with a UGR<19 value is mandatory and for public areas UGR<22.

This filter allows you to refine your search by selecting specific types of light sources. Choose from options such as LED bulbs, LED tubes, or LED spots to find the perfect lighting solution for your needs.

The IP value indicates the degree of protection against the ingress of moisture and dust. The 1st digit (0 = not protected until 6 = completely dustproof) indicates the protection against dust. The 2nd digit (0 = not protected until 8 = protected against immersion) indicates the protection against water. Products with an IP44 rating are splashproof and products with an IP65 rating or higher are (completely) dustproof and waterproof.

The impact protection value (IK) stands for impact resistance and protection against vandalism. This is expressed in combination with 2 digits (IK00 - IK10). Products with IK00 are not protected against resistance. Products with IK10 offer resistance to shocks of 20 Joule and are also vandal-proof.
