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. |
Energy efficiency class | E |

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.

This indicates which wattage of your old/conventional lighting is replaced by this LED product.
|
Replaces (Watt) | 42 |
|
i
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 | 20 |
|
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.
|
Dimmable | Not Dimmable |

i
The cap/base of a bulb is the part that connects it to the socket in the fixture. E27 (Edison screw) and E24 (small Edison screw) caps/bases are among the most popular, although this depends on your location. GU10 is generally the most common cap/base for spotlights. Check which cap/base you need carefully as many other types are also available.

Cap / Base | GX24q-4 (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. |

Colour temperature (Kelvin) | 4000K - Cool White |
|
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 | 840 Cool White |
|
i
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 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) | 2250 |
|
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) | 112 |

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.

A ballast can be seen as an energy regulator that switches on the lighting. Is there a starter in the fixture? Then this is a conventional ballast (EM). Fixtures with an electronic ballast (HF) don't have a starter. A LED driver can be compared to an electronic ballast and only works with LED lighting.
|
Ballast | Electronic (HF); Mains (AC) |

Because you can set the direction of the light yourself, a rotatable LED tube is extra efficient with energy. Moreover, the light does not shine around 360 degrees unnecessarily, as is the case with conventional fluorescent tubes.
|
Rotatable | No |

It may happen that the length of this product differs from your old lighting fixture. As a result, the product does not fit in your current fixture or in the relevant place.
