A par cans lighting, short for Parabolic Aluminized Reflector Lighting, is a type of lighting fixture commonly used in the entertainment and stage lighting industry. It features a sealed beam lamp, which produces a powerful and focused beam of light with a defined beam angle. PAR cans lighting come in various sizes and are known for their versatility and ability to create vibrant, colorful lighting effects.
The terms "PAR" and "PAR can" are often used interchangeably to refer to the same type of lighting fixture. These two terms mean the same thing, and both describe the kind of light that the light fixture produces. Now, our shells were made of aluminum, but now our mainstream is to use cast aluminum, sheet metal, or plastic.
While PAR and Fresnel are commonly used in stage lighting, they differ significantly in design and light distribution. PAR lights produce a more focused, intense beam, ideal for spot or accent lighting. On the other hand, Fresnel lights have adjustable lenses that allow for a broader, softer shaft, making them suitable for flood and general lighting. Although PAR lamps can now be adjusted in focus, Fresnel lamps are better for adjusting the angle.
