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 |

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) | 30000 |
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.

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 | 18.5W |

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.

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 | 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. |
Number of pins | 4 |

 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 |

Colour temperature (Kelvin) | 4000 Cool 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 |

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 |

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. |

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) | 2250lm |
|
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 | 121 |
| Product Type Category | PL-T / Dulux-T T-E LED | |

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 |

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) without starter |

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 |
