What are LED colour temperatures?
The colour temperature for lighting is based on a scale running from Warm White at the red end of the spectrum, through to White at the blue end with Natural White in between.
It is measured in degrees Kelvin or (K), ranging from 2000K-3000K (Warm White), 3100K-4500K (Natural White) to 4600K-6500K (White)
What is the brightest type of light in the LED colour temperature range?
LED lights in the White range of 4600K – 6500K are the brightest LED lights. Natural Light, (3100K- 4500K), is the LED colour temperature closest to natural daylight. Warm White is the softest light at 2000K – 3000K.
How to choose the perfect LED colour temperature
The lower the K number, the warmer the colour. Warm Whites range from a rosy glow through to a golden hue with White at the other end of the spectrum emitting light which is tinged with blue.
The ideal choice of colour temperature involves considering both the interior design aspects of the setting and the way the space is intended to be used. The right choice of colour temperature can enhance the existing colour scheme or used to correct deficiencies, for example introducing Natural White light to a room with inedequate natural daylight.
A lighting colour temperature of 5500K is the best for your eyes in daylight hours, turning down to 3000K at night. For kitchens a mix of lighting works best, with brighter light used for food preparation areas and warmer light for dining.
2000K – 3000K
