The tungsten halogen lamp emits a whiter light than conventional incandescent lamps. Its light colour is in the range of warm white. Due to the continuous spectrum, the colour rendition is excellent. Its compact form makes the tungsten halogen lamp an ideal point light source. The particularly good directability of the light produces brilliance. The luminous efficacy and life of tungsten halogen lamps is above that of ordinary incandescent lamps. Tungsten halogen lamps can be dimmed and do not require any additional control gear; low-voltage halogen lamps, however, must be powered via transformers.
