What is one characteristic of a reflectorized lamp?

1. It has a rough surface

2. It intensifies the beam of light

3. It uses multiple filaments

4. It has no reflective coating

The correct answer is: It intensifies the beam of light

A reflectorized lamp is specifically designed to enhance the intensity of light emitted from the bulb. This is achieved through its reflective surfaces that redirect and concentrate the light into a more focused beam. The design often features a smooth, polished reflector that aids in amplifying the light output, making it suitable for applications requiring more directional lighting. In contrast, a lamp with a rough surface would scatter light instead of intensifying it, making it less efficient in directing light to a specific area. Multiple filaments are not a defining characteristic of reflectorized lamps; rather, this pertains to some types of incandescent bulbs that generate ambient light. Lastly, a lack of reflective coating would negate the benefits of a reflectorized design, leading to a wider dispersion of light instead of a focused beam.
