By purchasing the Full box quantity, your products will come as packaged by the manufacturer.

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 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.

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).

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. 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).

The colour rendering index (CRI) indicates how accurately colours are represented under a beam of light. The index goes from 1 to 99, with a CRI of 1 being the poorest and a CRI of 99 being the best possible. Be careful not to confuse colour rendering with colour temperature (K).

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.

Lumen (lm) is the term used to describe the total amount of visible light emitted by a light source. The higher the number of lumens, the brighter it is.

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.

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).

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.
