PAR stands for "Parabolic Aluminized Reflector," which refers to the shape and design of the light bulb. PAR bulbs are commonly used in stage and architectural lighting due to their focused and directional beam.
The term "PAR can" originates from the combination of "PAR" (Parabolic Aluminized Reflector) and "can," referring to the cylindrical metal housing that holds the PAR bulb. The design of the can allows for easy mounting and positioning, making it a popular choice for stage lighting applications.
As mentioned earlier, "PAR" in PAR can stands for "Parabolic Aluminized Reflector," emphasizing the reflective coating inside the bulb that shapes and directs the light beam.
The main difference lies in the beam angle and light distribution. Fresnel lanterns have a wider beam spread, providing a soft and diffused light, ideal for theater and film lighting. On the other hand, PAR cans have narrower beam angles, producing more focused and intense beams, making them suitable for highlighting specific areas or objects.
PAR bulbs come in various types, identified by their numbers. Common types include PAR16, PAR20, PAR30, and PAR38, where the number indicates the diameter of the bulb in eighths of an inch. Each type has its unique beam angle and application, allowing for versatile lighting solutions.
