All You Need to Know About the LED Linear High Bay

Hykolity 265W LED Linear High Bay Light Ceiling Lamp

There are few things more essential to a safe workplace than lighting. And when it comes to large indoor spaces, LED high bay lights are the ideal solution. They are one of our higher output fixtures and can illuminate vast vertical and horizontal spaces. We offer linear style high bays in different configurations so here are some quick facts:

  • Available in 2 ft. 110W or 165W, & 4 ft. 223W, 265W, or 325W
  • 14410 - 34450 Lumens
  • 5000K White Color Temperature
  • 120° Beam Angle
  • 120-277V Working Voltage
  • Frosted Diffuser Lens
  • Includes V-brackets & Chains for Pendant Mounting

You might be asking, “These features sound great and all, but what's it going to do for me?” So if you need a deeper look, here are a few benefits that you can take advantage of using the LED linear high bay. Click on a topic below to jump to that section directly.

0-10V Dimming

Our LED linear high bay is compatible with 0-10V dimmers, saving you even more on your electricity bill. When you dim this LED high bay, its wattage lowers along with its light output because it requires less power. However, not every dimmer will work with this luminaire since many have wattage restrictions.

The Lutron Diva DVS-TV, our recommended 0-10V dimmer switch, has a 450W wattage capacity. Wire one 4 ft. high bay to one dimmer so you do not blow out the latter. You can wire two 2 ft. linear high bays since their combined wattages have enough of a buffer from the max load (ie. 2 x 165W = 330W). Read your dimmer switch’s instructions to ensure the wattage capacity.


This high bay's LED driver is externally placed, extending its lifespan to 50000 hours. Many high bay fixtures on the market are one solid body with their drivers built-in. To achieve a longer lifespan, the linear high bay's external LED driver is kept a half inch away from the main body. This allows airflow more room to pass through, providing better heat dissipation to extend the LED high bay’s operating life.

Broadly Applicable

Many industrial and commercial buildings benefit from and require LED high bay lighting. These areas are often vast and have high ceilings which are needed to house inventory or tall equipment. Some common settings include:

  • Warehouses
  • Distribution Centers
  • Manufacturing Facilities
  • Gymnasiums
  • Department Stores
  • Supermarkets

You can equip the LED high bay with two optional modules that will increase its value. Using motion sensors will enable you to stack on energy savings and extend the life of your luminaires by turning them on only when activity is present. When no movement is detected, the LED high bay will stay off until there is motion. this autonomous system is ideal in places where occasional tasks are done like storage rooms.

If you need your high bay fixtures to stay on in case of a blackout or power cutoff, use our emergency drivers. If your luminaires' power is cut off, the emergency LED driver will retain 8W, 12W, or 15W to power your high bays so you can wrap up your work. As a result, it will protect your LED high bay from overdriving, underdriving, overheating, or short-circuiting.

Some building codes may require you to equip your LED high bays with emergency ballasts. The mandate is part of your state’s green initiative for energy efficiency. According to California’s Title 24 code, fixtures must be wired to emergency LED drivers that have a minimum rated life of 30000 hours when operated at or below the specified case temperature. Check with your state’s building codes to find out any ballast requirements.

Adding these accessories will increase your upfront costs in the short term, but you’ll realize long term savings through extended lifespans.

How Many Fixtures Do I Need?

To find out how many fixtures you need to achieve full light coverage, you must first measure your space’s dimensions. Enter these numbers in a light layout visualizer or calculator that you can find online.

As an example, we’ll use the dimensions of a high school basketball court. Indoor basketball courts are wide in space and have high ceilings because of the sports activity that take place, making LED high bays a necessity.

We will determine this baseline with’s Visual Interior Tool using another product with similar specs. With a length of 84 feet, a width of 50 feet, and a 43 ft. high ceiling, we recommend using 6 LED high bays and arranging them in a 3x2 array. This will yield 28-foot candles each.

We suggest hang mounting the linear high bays using the included V-brackets and chains. In our example, we chose 43 feet as the height because that is the tallest height you can set the high bays without leaving unlit zones within an 84x50 space. You can still surface mount them on your ceiling, but you may need to install additional fixtures.

Which LED High Bay Should I Use?

LED high bays can not only appear rectangular but also come in circular forms. UFO-style high bay lights are a great alternative to the linear style because of its striking form and unique features.

Unlike linear high bays, it has sharper beam angles, refinable with polycarbonate lenses, to adequately illuminate a small area. This, along with its circular diode arrangement and lumen range, makes our LED UFO lights ideal for lower placement from the floor. Contrastly, LED linear high bays have a wider diode arrangement to create a wider beam angle. They perform best when ceiling mounted higher, making them an excellent solution for lighting up aisles.

The choice also comes down to your aesthetic taste. Do you want the traditional high bay appearance? Choose the UFO style. If you like the boxy fluorescent lamp look, go for the linear style.

How Does it Compare to Traditional High Bays?

While LED lighting is becoming more and more adopted, many warehouse and industrial settings still use high-pressure sodium (HPS), metal halide (MH), or fluorescent high bay lights. They still have their merits, but across the board LED lighting shines much brighter and more efficiently.

Commercial LED lighting is more energy efficient, has better lighting quality, and requires less maintenance than fluorescent lighting. They efficiently emit energy as light as opposed to heat. They are also unidirectional, meaning they point in one direction so none of its output is wasted. Industrial-grade LED lights are made using up-to-date technology that improves lighting in metrics like color rendering (CRI), color temperature (CCT), and foot candle coverage. Lastly, LEDs are made to last longer which translates to decreased maintenance requirements like replacements and general upkeep.

Like LED linear high bays, fluorescent high bays are similar in shape, affordability, and efficiency. But despite their lower upfront costs and high efficacy, their lifespan decreases with every flip of the switch. The tube light bulbs contain mercury so they require a special disposal process. Additionally, they have higher maintenance costs due to labor and tube light bulb and ballast replacements. Commercial LED fixtures are guaranteed to work for about 50000 hours and do not need additional equipment to function, which drives up costs.
