High Bays- as the name suggests- are lighting fixtures used to illuminate spaces with ceilings more than 25 ft in height i.e. warehouses, garages, manufacturing units, and gymnasiums etc. Uniquely-shaped, disc-like High Bay lights are known as UFO High Bays.
This fixture can be installed easily and is highly preferred in industrial lighting because it helps distribute light over a large area. If you are looking to replace T5 or T8 fixtures there, the ideal choice is an LED Linear High Bay.
