A low bay light is typically used with ceiling heights 20' or less. High bay lights are typically used when ceiling heights are 20-45' high. Most notably, a low bay light usually features some type of diffuser on the bottom of the light to spread the light in a manner reflective of the lower ceiling height.
LED high bay lights are specifically designed for taller ceilings and larger areas. They focus light more directly to create powerful illumination at a long range. This makes them perfect for commercial and industrial applications such as warehouses and retail stores.
Used to light areas with lower ceilings, low bay lighting options have diffusers at the bottom of the fixtures. These diffuse the light, cutting down on the harsh reflections that lower ceilings can cause. The result is a more natural, pleasing light in rooms with low ceilings, whether at work, at home or play
