High bay lighting is designed for ceilings that are 20 feet or higher, typically found in industrial and commercial settings like warehouses, factories, and gymnasiums. These lights provide a broad, powerful illumination to cover large areas and are often equipped with reflectors or lenses to direct light downward, minimizing shadows and ensuring even distribution. High bay lights are usually more powerful, with higher lumen output to effectively illuminate the space from a greater height. Low bay lighting, on the other hand, is intended for ceilings that are 20 feet or lower, commonly used in retail stores, workshops, and garages. These lights are designed to provide adequate illumination for smaller spaces with lower ceilings. Low bay lights typically have a lower lumen output compared to high bay lights, as the light does not need to travel as far to reach the ground. They often use diffusers to spread light evenly and reduce glare. In summary, the primary differences between high bay and low bay lighting are the ceiling height they are designed for, the lumen output, and the light distribution method. High bay lights are suitable for higher ceilings and larger spaces, while low bay lights are ideal for lower ceilings and smaller areas.
