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.

i
The lifespan is an indication of the number of hours a product will last. This refers only to the hours the product is actually on. LED lighting has a significantly longer lifespan than conventional lighting. LED lighting therefore lasts much longer. How long you can actually use a product depends on the extent of its (daily) use. |
Average Lifetime (h) | 50000 |
Technical Information
|
i
 Lighting with a built-in emergency lighting unit (battery) continues to burn for a certain time if the power fails. |
Emergency Lighting | No Emergency Unit |

A fixture with a tiltable design makes it possible to direct the lighting specifically at an object or surface. This can play a particularly important role in shops (putting a new collection in the spotlight) or galleries (accentuating works of art). It can also influence the purchasing behaviour or interpretation of visitors.
|
Tiltable | No |

i
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.
|
Technology | LED Integrated |
|
i
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.
|
Voltage (V) | 220-240 |
|
i
Dimmable bulbs work in combination with a dimmer switch and allow you to determine the desired light output. Dimming also provides energy saving potential because less power is required when the lamp is producing less light.
|
Dimmable | Not Dimmable |

i
 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 Code | 830 Warm White |

Colour temperature (Kelvin) | 3000 Warm White |

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.
|
Colour Rendering (Ra) | 80-89 |
|
i
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:
By choosing your preferred light colour options, you are one step closer to the right light product. |
Light colour options | Single Color |

i
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.
|
Beam Angle (degree) | 90 |
|
i
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.
|
Luminous Efficacy (lm/W) | 100 |
|
i
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.
|
Power factor | >0.90 |
|
i
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.
|
Unified Glare Rating | < 23 - for general areas |
| Optical Cover | Opal | |
| Product Type Category | LED Downlight |
Fixture Information
|
i
 Are you specifically looking for an (LED) fixture that you can install on the ceiling, wall or floor? With this filter, you can easily select your preferred type of mounting. Please note that certain fixtures can be mounted in multiple ways using the installation materials supplied (e.g. a LED bulkhead). Mounting is also possible using individually purchasable fixture accessories, such as a frame or suspension kit for a LED panel. |
Mounting Method | Recessed |

The cut out of a fixture differs from the dimensions and specifically refers to the size of the hole in the ceiling that is required to securely fasten the light source during installation.
|
Cut out (mm) | 280 |

i
 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. |
IP-rating | IP44 |
|
i
 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. |
Impact Protection (IK) | IK03 - 0.35 joule |
| Operating Temperature | -20 to +40 | |
| Housing | Aluminium | |

i
The colour of the fixture can play a major role in the interior design of a room. You can opt for a neutral white design or a darker colour, such as black or silver, to make the light source stand out or even turn it into a decorative feature on its own.

Sensor Information
|
i
Lighting with a sensor only turns on when it receives a specific signal. This reduces energy costs. The (built-in) sensors respond to darkness (twilight switch) and/or movement (motion sensor).

Type of sensor | No Sensor |
