|Energy efficiency class||A||
EU guidelines dictate energy labels on electronic products to represent the energy efficiency of the device. This is indicated in levels (A++ to E), with A++ being the most efficient and E the least efficient.
|Average Lifetime (h)||20000|
|Cap / Base||2G7 (4-pins)||
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.
|Number of pins||4||
It’s important that you pick a bulb with the same socket type as your current bulb in order for it to be compatible with your light fixture. A lamp with a 2-pin socket type uses a starter and a conventional ballast. A 4-pin socket type works in combination with an electronic ballast without a starter.
|Colour temperature (Kelvin)||4000K - Cool White||
The colour temperature refers to the colour produced by a light. It's measured in Kelvin (K) and ranges from warm white (1700K - 3000K) to daylight white (6500K). Neutral white (3100K - 5000K) is mainly used for general lighting applications.
|Colour Code||840 - Cool White||
The colour code is a combination of the colour rendering index (CRI) and the colour temperature (K). The first number refers to the CRI (1 = very poor colour rendering, 9 = maximum accuracy). The second and third numbers refer to the colour temperature. For example, a light with a colour code of 830 has very good colour rendering and produces a warm white light.
|Colour Rendering (Ra)||80-89||
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).
|Light Output (Lumen)||400||
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.
A light with a sensor can turn on automatically. Depending on the sensor it has, this can be whenever it detects motion or a lack of light, or both.
|Luminous Efficacy (Lm/W)||57||
The lumen to watt ratio indicates the the efficiency of the bulb in terms of how much light is output per watt of energy consumed. An LED bulb emits more than 100 Lm/W, while an incandescent bulb typically has an efficiency of 10 Lm/W.
|Features||High Lumen Output, Long Lifetime|
