Let’s dive into the basics and uncover how these unassuming lights can transform any performance space into something spectacular.

What Are PAR Lights?

PAR lights, short for Parabolic Aluminized Reflector, are a type of stage lighting fixture known for their versatility and relatively even light distribution. They're characterized by their parabolic reflector, which is a bowl-shaped mirror designed to focus and direct the light emitted from a lamp (typically a tungsten-halogen or LED lamp) placed at its focal point. This design contributes to several key features:

1. Even Light Distribution (relatively)

While not as tightly focused as beam lights, PAR lights produce a relatively even, soft-edged beam of light, making them suitable for wash lighting (covering a large area with even illumination) and backlighting. The exact spread of the light depends on the lens used; different lenses create different beam angles.

2. Color Mixing Capabilities

PAR lights are often used with gels (colored filters) placed in front of the lamp to create a wide range of colors. This makes them ideal for creating moods, highlighting specific areas, or matching the overall color scheme of a production. Modern LED PARs often have built-in color mixing capabilities, eliminating the need for gels.

3. Variety of Beam Angles

PAR cans are available with a wide range of lenses, resulting in different beam angles. Narrow beam angles create more focused pools of light, while wider angles create a broader wash. This versatility allows them to be used for a variety of applications.

4. Durability and Reliability (Traditionally)

Traditional tungsten-halogen PAR lights are known for their ruggedness and reliability, though they generate significant heat and consume considerable power.

5. Energy Efficiency (LED versions)

The advent of LED PAR lights has significantly improved energy efficiency and reduced heat output, making them a more sustainable and cost-effective option. LED PARs also offer longer lifespans compared to their tungsten-halogen counterparts.

6. Dimmability

Both tungsten-halogen and LED PAR lights are dimmable, allowing for precise control over light intensity.
