In order to ensure that the light reaches the ground evenly and reduces the waste of light, the led high bay fixtures are equipped with reflector or a lens. With lens angles of 90° or narrower 60°, this design makes bay lighting spread more efficient.
LED low bay beam angle is 120°, which is because they require fewer lumens to reduce less light. Low ceiling lighting no need to worry about the waste of light like led lowbay lighting.
