Frequently asked questions

What is the difference between high bay and low bay lights?

High bay lights are designed for tall ceilings, typically above about six metres, while low bay lights suit lower ceilings in workshops, shops and smaller warehouses. High bays often use narrower beams to push light down to the floor, while low bays spread light wider at a lower height. The range here includes LED high bay and low bay lights.

What are the different types of high bay lighting?

High bay lighting comes as round UFO-style LED fittings, linear LED high bays and older metal halide or fluorescent fittings, which LED versions now usually replace. Fittings also differ by beam angle, wattage, colour temperature and ratings, such as IP65 for dusty or damp spaces. The range here includes LED high bays with selectable wattage and colour temperature.

How many high bay lights do I need?

The number of high bay lights you need depends on the floor area, the mounting height, the fitting's light output and the lux level the task needs. A lighting design or lux calculation from the fitting's photometric data gives an exact figure. As a rough guide, fittings are often spaced about one to one and a half times their mounting height apart.

How do you install high bay lights?

High bay lights are usually hung on a hook, chain or bracket fixed to the roof structure, or surface mounted, then wired to the mains by a qualified electrician. Check the structure can take the fitting's weight, use a safe access platform, and connect any dimming or sensor wiring before hanging. The range here includes low bay lights supplied with suspension hooks and chains.

What is a high bay light?

A high bay light is a powerful light fitting made for high ceilings in spaces such as warehouses, factories, gyms and sports halls. It is hung or mounted high up and directs a strong beam down to the floor. Modern high bays use LEDs, which use less energy than older metal halide lamps. The range here includes LED high bays and lens accessories.
