Breaking Down the PAR38 Nomenclature

The PAR38 designation is an acronym that stands for “Parabolic Aluminized Reflector, 38 eighths of an inch in diameter.” Let’s break down each part of this nomenclature:

• Parabolic: PAR bulbs feature a parabolic-shaped reflector that concentrates light in a specific direction, enhancing beam control and intensity.

• Aluminized: The reflector is coated with a thin layer of aluminum to improve reflectivity and maximize light output.

• 38 eighths of an inch: This refers to the bulb’s diameter, which measures approximately 4.75 inches (12.1 centimeters).

Types of PAR38 Light Bulbs

PAR38 light bulbs come in various types to cater to different lighting needs:

• Halogen PAR38: These bulbs produce a warm, incandescent-like light and are commonly used in outdoor lighting and accent lighting.

• LED PAR38: LED PAR38 bulbs are energy-efficient and long-lasting, offering excellent color rendering and brightness. They are ideal for both indoor and outdoor applications.

• CFL PAR38: CFL PAR38 bulbs provide energy savings compared to halogen bulbs while maintaining a warm light output. They are suitable for general lighting purposes.

Applications of PAR38 Light Bulbs

PAR38 light bulbs find applications in a wide range of settings, including:

• Outdoor lighting: PAR38 bulbs are commonly used in floodlights, spotlights, and landscape lighting due to their ability to project light over long distances.
