The European Union has drawn up guidelines for energy labels for lighting. The energy efficiency of bulbs and luminaires is expressed in classes (A to G). Energy label A is the most efficient and energy label G the least. The energy label is also stated on the packaging of a product.

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.

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).

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.

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.

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.

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).
