“Incandescent light and sunlight are two golden standards of lighting.”
The main components of an incandescent lamp are only a tungsten filament and a glass bulb. The filament glows when heated sufficiently by an electric current due to electrical resistance. Like other heating elements or the sun, it radiates a continuous spectrum with the result of excellent colour rendition. The visible light is warm white color (2700K) with high degree of infra-red and very low UV radiation.
