Which type of lamp has a soft glass enclosure?

The correct answer is the type of lamp that is characterized by a soft glass enclosure, which is typically found in BR lamps (Bulged Reflector lamps). BR lamps have a larger bulb diameter and a bulged shape that allows for broader light distribution and a softer beam spread, making them ideal for ambient lighting in residential and commercial applications. The soft glass helps to diffuse the light, reducing glare while providing a warm and inviting illumination.

In contrast, other lamp types like PAR (Parabolic Aluminized Reflector) lamps usually have a hard glass structure designed for more focused light output, while MR (Multifaceted Reflector) lamps are typically made with hard glass as well and intended for directional lighting. AR (Aluminum Reflector) lamps also do not feature the soft glass design. Understanding these distinctions is essential for making informed decisions about lighting solutions based on the intended lighting effect and application.
