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.

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.

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.

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. 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.

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 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.

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: 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 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.

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.

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).

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.

The shape tells you something about the design of a LED bulb or conventional bulb. This literally describes the design of the light source, for example a pear or candle shape. In some cases, the name of a product also tells you something about its size. A GU10 AR111 LED spotlight, for example, has a diameter of 111 mm.

The exact shape tells you something about the design of an LED bulb or conventional bulb. This is the technical name for the bulb shape, where the letter(s) describe the design of the light source and the number tells you something about the size of the bulb. For example, P45 means a pear shape with a diameter of 45 mm, while G125 is a globe shape with a diameter of 125 mm.
