In the simplest terms, a light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is produced when the particles that carry the current (known as electrons and holes) combine together within the semiconductor material.

Since light is generated within the solid semiconductor material, LEDs are described as solid-state devices. The term solid-state lighting, which also encompasses organic LEDs (OLEDs), distinguishes this lighting technology from other sources that use heated filaments (incandescent and tungsten halogen lamps) or gas discharge (fluorescent lamps).

Colour temperature

Perhaps the two most important factors when choosing an LED light source are colour temperature and colour rendering. We’ve touched on colour temperature in previous blogs, but feel It’s such an important subject it’s worth giving this more attention. You can read our separate blog dedicated to colour rendering here.

When we talk about colour temperature we are referring to the warmth or coolness of light. Warmer light being more yellow, cooler being more blue. There is no ‘standard’ ‘White’ LED. You need to make a choice when you purchase your fittings, do you require a warm or cool light.

Candles are very warm of course, basically yellow/orange, whereas daylight at noon is very cool. The colour or warmth of white light is ranked on a scale, The Kelvin scale, the warmer the colour the lower the colour temperature. Candles being around 2000 degrees Kelvin (k) while daylight typically 5500 – 6500k.
