PAR (Parabolic Aluminized Reflector) light bulbs are designed to provide directional lighting, which means they are ideal for task lighting, accent lighting, and outdoor lighting applications. They are often used in recessed lighting fixtures, track lighting systems, and outdoor floodlights.

As you mentioned, PAR bulbs have a shorter body than BR (Bulged Reflector) bulbs and a bowl-shaped reflector that directs light in a specific direction. The pressed lens inside the lamp helps to create a more defined edge to the light, which can be beneficial for highlighting specific objects or areas.

PAR bulbs come in different sizes and wattages, and they are available in both halogen and LED options. Halogen PAR bulbs are known for their high-quality color rendering and can provide a warm, inviting glow. LED PAR bulbs are energy-efficient and have a longer lifespan than halogen bulbs.

Overall, PAR bulbs are a versatile lighting option that can be used in a variety of settings to provide directional lighting with a more defined edge.
