LED PAR lights combine light-emitting diodes (LEDs) with a parabolic reflector design. LEDs emit light when powered by an electric current. The parabolic reflector focuses and directs this light into a controlled beam. LED PAR lights can have RGB or RGBW LEDs for color mixing. They’re controlled through systems like DMX, allowing for precise color, intensity, and effect adjustments. LED technology’s energy efficiency and directional control make these lights popular for spotlighting and various lighting effects in stages, events, and more.
