Lighting is a vital determinant of a room’s ambience and overall mood. Yet it is an interior design element often overlooked or not valued enough. Well-placed lighting adds another dimension to a space, bringing a room to life or enhancing its functionality.
LIGHT TEMPERATURE
So what is warm and cool light or colour temperature? According to Simon Davey, Dyson’s design engineer, colour temperature measures different types of visible light. Measured in units of Kelvin, visible light is just a particular type of electromagnetic radiation, with different colours corresponding to different wavelength ranges.
Cool light has a higher proportion of shorter wavelengths and is measured at around 6,500 Kelvin. Longer wavelengths produce more orange or red light, referred to as ‘warm’ light, approximately 2,700-1,800 Kelvin.
As for its different effects, Joseph Ho, co-founder
