A High Bay Fixture fitting, depending on the light source, can take on many forms and shapes. If you consider a Metal Halide or High Pressure Sodium fixture, they typically consist of a large heat sink block at the top of the fixture that typically houses the fixtures ballast.
Below is an aluminum or acrylic dome and at the top of the dome is the HID bulb. These bulbs typically come in two wattage’s, 400 and 1000. 400 Watt Fixtures tend to be installed in ceiling heights no higher than 30 feet, 1000 watt fixtures are typically 40 feet or higher.
When the same conventional LED high bay light uses a different beam angle reflector. The efficiency is totally different. So please don’t use the small angle reflector to change the beam angle of LED. Unless you don’t care the lumen output.
What are high bay lights ?
As their name implies, high-bay lights are used to illuminate spaces with high ceilings. That usually means ceilings ranging from 20 feet to approximately 45 feet. Low-bay lights, on the other hand, are used for ceilings 20 feet and under. Because a high-ceiling location has more space to fill, a high-bay by definition is a powerful light source that can brighten up a large area.
Given their placement, high-bay lights are natural fits for commercial and industrial uses. They have multiple applications across a range of industries, including workshops, factories and assembly lines. You will also see high-bay lights in large recreational facilities and gyms. These lights are excellent for illuminating storage facilities and warehouses as well. They can be used for large conference halls, event centers, or indeed for any place that needs lighting from an elevation of more than 20 feet. They are even used in hangars and other large, cavernous buildings.
High- and low-bay lighting – typically used for general lighting for industrial buildings and often big-box stores.
