Every bulb or fixture has an energy efficiency class A to G. Energy label A is the most efficient and G the least. LED lighting is the most sustainable lighting technique. Even if a LED bulb is rated E or lower, they still save 70% of energy compared to conventional lighting with the same energy label. Why is it the same label then? To motivate LED brands to get even more durable. |

Technical Information
|
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.

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).
|
Wattage | 28 |
|
i
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 cap/base of a bulb is the part that connects it to the socket in the fixture. In the UK, B22 (Bayonet) caps/bases are still the most popular, although E27 (Edison screw) caps/bases are becoming increasingly popular. GU10 is the most common cap/base for spotlights. Check which cap/base you need carefully as many other types are also available.
|
Cap / Base | GR10q (4-pins) |
|
i
With (LED) energy-saving light bulbs there are fittings/lamp bases with 2 pins or 4 pins. Always choose a energy-saving bulb with the same cap/base, otherwise it will not fit in the fixture and will not work. Energy-saving bulbs with a 2-pin base work with a conventional ballast (EM) incl. starter. Energy-saving bulbs with a 4-pin socket work with an electronic ballast (HF) without a starter. |
Number of pins | 4 |

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 | 835 Warm White |

Colour temperature (Kelvin) | 3500 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.
|
Colour of Light | White |

i
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.

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.
|
Luminous Flux (Lumen) | 2050 |
|
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.
|
Lumen per watt | 73.2 |

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.
