What does the "R" in the designation 65BR30 indicate about the lamp?

The designation "65BR30" refers to a specific type of lamp, and the "R" in this designation indicates that it is a reflector type lamp. Reflector lamps have a built-in reflective surface that helps focus and direct the light from the bulb, allowing for more efficient lighting and improved distribution of light in a specific area. The "BR" stands for "bulged reflector," which characterizes the shape and functionality of the lamp.

Understanding the designation of lamp types is crucial for lighting technicians, as it helps them choose the appropriate lamp for a specific application, ensuring optimal light output and efficiency. The other aspects indicated in the designation, such as the size and wattage, complement the reflector type but do not define its primary characteristic, which is its ability to direct light effectively.
