PAR lamps have the characteristics of general service lamps. They offer a warm light effect with excellent colour rendition, switch on without time delay and can be dimmed easily. The parabolic reflector of the PAR lamp ensures defined light beam angles. Directional luminaires have a glare-free Darklight reflector and, like the downlights of the same design, are recess-mounted in ceilings. Directed perpendicularly, they produce light to rival that of conventional downlights. The ability of the lamp and reflector to be tilted through up to 15° from the vertical and be rotated through 360° horizontally is characteristic for directional luminaires.

This allows the beam to be aimed at almost any area of the room, to provide the intended lighting accentuation. Furthermore, when fitted with a sculpture lens, a directional luminaire can produce an even vertical illuminance. High protection mode directional luminaires are suitable especially for the transitional areas between indoors and outdoors. In indoor areas where protection against moisture or dust is required, they ensure high-quality lighting even in these harsh environmental conditions.
