What is a high bay light?
A high bay light is a powerful lighting fixture designed for spaces with high ceilings - typically 6 metres (20 feet) or more. They’re commonly used in warehouses, factories, gyms, large retail stores, and industrial facilities. Modern LED high bay lights offer excellent brightness, energy efficiency, and a long lifespan, making them a cost-effective replacement for older metal halide or fluorescent fixtures.
How many high bay lights do I need?
The number of high bay lights you need depends on the size of the area, ceiling height, light output (lumens), and required brightness level (lux). To calculate high bay lighting, measure the total area, determine your target lux level, and divide by the fixture’s lumen output to estimate how many units are needed. For example, warehouses may require 150–300 lux, while sports facilities might need 300–500 lux. Using a professional lighting plan ensures optimal coverage and avoids dark spots.
How high do LED high bay lights need to be?
LED high bay lights are typically installed at heights from 6m (20ft) to over 12m (40ft). The exact mounting height depends on the beam angle - narrow beams (60°) work best for higher ceilings, while wider beams (90°–120°) suit lower high-bay applications. Proper mounting height ensures uniform light distribution and reduces glare.
How to hang high bay lights?
High bay lights can be mounted using chains, hooks, or pendant mounts, depending on the fixture design and ceiling structure. Steps include:
- Turn off mains power.
- Secure mounting hardware to the ceiling or supporting structure.
- Hang the light fixture using the chosen mounting method.
- Connect the wiring according to the manufacturer’s instructions.
Always ensure fixtures are securely mounted and compliant with local electrical regulations - professional installation is recommended.
What is the difference between low bay and high bay LED lights?
The main difference is mounting height. Low bay lights are designed for ceilings under 6m (20ft), while high bay lights are built for taller spaces, with optics that focus light downward over a greater distance. High bay fixtures usually have higher lumen output and narrower beam angles to ensure bright, even illumination in large areas.
