A PAR lamp is an example of which type of lamp?

1. Rough service lamp

2. Capsule lamp

3. Double-ended linear lamp

4. Reflectorized lamp

The correct answer is: Reflectorized lamp

A PAR lamp, which stands for Parabolic Aluminized Reflector lamp, is categorized as a reflectorized lamp. These lamps utilize a parabolic reflector to direct the light produced by the bulb, allowing for more efficient lighting by concentrating the light in a specific direction. This feature makes them ideal for applications where focused lighting is required, such as stage lighting, architectural applications, and outdoor lighting. The design of a PAR lamp includes a bulb that is optimized for reflecting light forward, which is a key characteristic of reflectorized lamps. This allows for controlled beam angles and enhanced illumination patterns, which are essential in many lighting scenarios. In contrast, rough service lamps are designed with thicker glass and are more resilient to vibrations, capsule lamps are typically smaller, often used in compact spaces and exhibit a different construction style, and double-ended linear lamps involve a completely different design intended for even and widespread light distribution. Thus, recognizing the unique reflective properties of PAR lamps highlights their classification as reflectorized lamps.
