Number of pins

Explanation

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.

Wattage

Explanation

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).

Colour Code

Explanation

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).

827 Extra Warm White 5
835 Warm White 5

Colour temperature (Kelvin)

Explanation

Light colour is also known as colour temperature and is expressed in Kelvin (K). You can choose from:

Extra warm white (1700K - 2700K). Atmospheric light. For places with a relaxing character.
Warm white (>2800K). Neutral and soft light. For common areas such as halls, corridors, foyers.
Cool white (>3400K). Fresh and natural light. Good for focus/concentration in schools and offices
Daylight white (>5000K). Equals natural daylight. Suitable for situations where a lot of light is needed.

2700K - Extra Warm White 5
3500K - Warm White 5

Cap / Base

Explanation

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.

GR10q (4-pins) 7
GR8 (2-Pins) 5

Dimmable

Explanation

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.

Luminous Flux (Lumen)

Explanation

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.

Energy efficiency class

Explanation

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.
