LED high bays are powerful overhead luminaires designed to illuminate spaces with tall ceilings, typically anywhere from 15 to 40 feet high. They deliver bright, uniform light over large floor areas while consuming far less energy than legacy metal halide or HID fixtures. From warehouses to gymnasiums, high bays are the workhorse of industrial and commercial lighting.
Types and options
The UFO high bay is a round, compact fixture that installs quickly and resists dust and moisture, making it ideal for open production floors. The linear high bay features a wider light spread that suits aisles and shelving. We also offer black-finish high bays for a cleaner architectural look. Many models are multi-wattage (for example 90W/120W/150W or 240W/270W/300W) and selectable CCT, letting you set both output and color temperature on a single fixture.
Where to use them
High bays are at home in warehouses, manufacturing plants, distribution centers, gymnasiums and arenas, big-box retail, hangars and workshops. Smaller UFO models with an E26 base can even retrofit residential garages and barns where standard sockets are already in place.
How to choose
Start with your ceiling height and the foot-candles your task requires; higher ceilings need higher lumen output and wattage. Confirm the voltage matches your panel — many of our high bays accept a wide 120-347V range, ideal for Canadian commercial circuits. Pick a color temperature: 4000K (40K) for a neutral look or 5000K (50K) for a crisp daylight effect; selectable CCT models keep your options open. Consider the IP rating for dusty or damp environments, and choose dimmable versions if you plan to use occupancy or daylight controls.
FAQ
What wattage do I need for my ceiling? As a rough guide, taller ceilings (over 25 ft) usually call for 200W and up, while 90W-150W suits ceilings in the 15-20 ft range. Lumen output matters more than wattage alone.
Can I install high bays on a 347V circuit? Yes — many models support 120-347V input, so they connect directly to common Canadian three-phase voltages without a separate driver.
Are these fixtures dimmable? Several models are 0-10V dimmable, which lets you pair them with sensors and daylight harvesting to cut energy use further.
