The LED PAR, which is a headlight with an aluminium case, is right for everyone in need of headlights which are sturdy and run on little energy. PAR headlights have some kind of history. The first headlights of that type (PAR is the abbreviation for parabolic aluminium reflector) were sold in the 1950’s. Nowadays, they are offered with light-emitting diodes (LEDs). You can adjust the intensity and colour of light with a digital multiplex (DMX), which is a common digital control program. The DMX is used in lighting to control dimmers, moving heads and many more.
