Reflector bulbs are a type of light bulb designed to direct light in a specific direction. They have a reflective coating on the inside of the bulb, which helps to focus the light output, making them ideal for use in recessed lighting, track lighting, and outdoor fixtures. These bulbs come in various shapes and sizes, including PAR (Parabolic Aluminized Reflector) and R (Reflector) types. These bulbs are commonly used in both residential and commercial settings due to their efficiency and versatility. Reflector bulbs can be found in different wattages and color temperatures, allowing users to choose the right lighting for their needs. They are available in both incandescent and LED options, with LED reflector bulbs being more energy-efficient and longer-lasting.
