CCT (correlated colour temperature)

Choosing a colour temperature:

LEDs make it possible to have a choice of white colours or ‘tones’. This allows easy customisation of an area to bring out the best in the materials and design of a room. With standard white LED lighting, these tones range from warm yellow to cool-blue white light, with several options in between. The graphic below is a reference that starts at a warm yellow colour on the left and fades into a cool blue colour on the right. Collingwood Lighting uses the industry standard Correlated Colour Temperature (CCT) rating to describe the tones of white light available.

The standard unit of CCT is the kelvin (K), so CCT is described as a ‘temperature’. CCT options range from 6500K cool white, 4000K natural white, 3000K warm white, 2700K warmer white and 2200K ember. You will find colour consistency across our entire range of products ensuring seamless installations. It can be tricky to decide what is best for your installation, but our skilled technical sales and lighting design teams are on hand to guide you through choosing the perfect white tone for your room.

Beam angles

25°

A narrow beam angle ideal for illuminating specific areas of interest with pin points of light. The most commonly used beam angle since the introduction of the halogen lamp in the ‘70s. Ideal for illuminating large areas and space between fittings is normally 1m-1.2m to create an even spread of light at floor level. Commonly used throughout residential and commercial environments. Can be used instead of a 38° beam angle when the ceiling is higher than standard or when looking to achieve a greater spread of light at floor and wall level. Commonly used in the hospitality market.

60°

This wider beam angle allows for greater spacing between fittings, up to 1.8m apart, or greater illumination at 1.2m spacings, meaning fewer luminaires are required. Also produces a more even spread of light at floor and wall level. Commonly used throughout residential and commercial environments. Ideal for high ceilings and illuminating large areas of space and is more commonly used in the commercial sector.
