BR Lamps vs PAR Lamps: A Detailed Comparison
August 30, 2023 by Chaim Gluck
Lighting plays a crucial role in our daily lives, influencing our mood, productivity, and even our well-being. With the advancement in technology, there are various types of light bulbs available in the market, each designed for a specific purpose. Two common types of reflector lamps that are often compared are BR (Bulged Reflector) lamps and PAR (Parabolic Aluminized Reflector) lamps. Although they may seem similar at first glance, there are several key differences between the two. This blog post aims to provide a detailed and thorough comparison between BR lamps and PAR lamps, discussing their design, applications, and advantages.
Design
BR Lamps:
BR lamps, or Bulged Reflector lamps, have a bulged shape that widens in the middle and narrows at the neck and base. This design helps in spreading the light more evenly across a wider area. The interior of the lamp is coated with a reflective material that directs the light forward. BR lamps are available in different sizes, usually indicated by a number that represents the diameter of the lamp in eighths of an inch. For example, a BR30 lamp has a diameter of 30/8 inches.
PAR Lamps:
PAR lamps, or Parabolic Aluminized Reflector lamps, have a parabolic shape that focuses the light into a tighter beam. The interior of the lamp is coated with an aluminized reflector that directs the light forward in a more concentrated beam. PAR lamps are also available in different sizes, with the number indicating the diameter of the lamp in eighths of an inch. For example, a PAR38 lamp has a diameter of 38/8 inches.
Applications
BR Lamps:
BR lamps are ideal for general lighting purposes where a softer and more diffused light is required. They are commonly used in residential settings, such as living rooms, bedrooms, and dining areas. BR lamps are also suitable for commercial spaces like offices, restaurants, and retail stores where a comfortable and inviting atmosphere is desired.
PAR Lamps:
PAR lamps are designed for applications that require a more focused and intense light. They are commonly used for accent lighting, spotlighting, and task lighting. PAR lamps are ideal for highlighting artwork, architectural features, or specific areas in a room. They are also used in outdoor settings for landscape lighting, security lighting, and stage lighting.
Advantages
BR Lamps:
Wide Beam Angle: BR lamps have a wider beam angle, which means they can illuminate a larger area with a softer and more even light.
Energy-Efficient: Most BR lamps available in the market are LED, which makes them energy-efficient and cost-effective in the long run.
Versatile: BR lamps are versatile and can be used in various settings, both residential and commercial.
PAR Lamps:
Focused Beam: PAR lamps produce a more focused and intense beam of light, making them suitable for accent and task lighting.
Durable: PAR lamps are designed to be durable and are often used in outdoor settings where they are exposed to the elements.
Variety of Beam Angles: PAR lamps are available in a variety of beam angles, from narrow spot to wide flood, providing flexibility in lighting design.
