As we all know,thanks to LED light low electricity usage, fast start times and high quality which help consumers save a lot of money on energy expenses and get better light in their homes, business and outdoor areas. However, Facing with a variety of high bay light, most of people are not sure which one is suitable to buy. Here LONGSUN  LIGHTING will discuss and show you some guide for your high bay applications.


1.Shape of High Bay Light

A high bay lighting can be round in shape, now commonly called UFO high bay lights or rectangle in shape, commonly known as linear high bay lights. Modern LED technology allows a lot of light in a small fixture, so its less about the light and which one is easier to install or you prefer the look of.


  • Round High Bay Light

Round high bay lights are also known as UFO high bay lights because of their saucer shape. They are the easiest high bay light to install because they only need to be hung at one point. Round high bay lights can be great for a place with higher ceilings. The light from UFO high bay lights averages 120 degrees which is ideal above 13ft high.


The illumination from round lights can be perfect for lighting tables in a restaurant setting. For this 13ft restaurant, you'd likely use LED high bay lights 100 watts and 3000K for a warmer light. Round UFO lights can still be used for large, open commercial space as well. For the 25ft open space LED high bay lights 240 watts and 5000K will light a building beautifully. Like our UFO high bay light as below:

  • Linear High Bay Light

Linear high bay lights may be more familiar to you. They're the lights you see in pretty much every grocery store and warehouse you visit. They are designed to look like the T8 bulbs, but they have nothing in common

Linear lights are great for really large buildings because they illuminate more space at one time. Linear lights can be long and wide or long and skinny. If your space has a lot of aisles or shelving, long linear lights are the best option. You can install the lights over each aisle so all your product is illuminated. Please check our SKY II series linear high bay light.


2.Wattage and lumens - How to choose the correct amount

High Bay LED lights are available in different watts, but its the lumens you need to keep an eye on. As LEDs get more efficient they will use less and less watts. You can easily choose one depending on the height where the high bay lights are installed. There are different watts for different levels of height:


• 10-15 feet – This height is ideal for lights with 10,000 to 15,000 lumens.

• 15-20 feet – This height is ideal for lights with 16,000 to 20,000 lumens.

• 25-35 feet – For this height, lights with 33,000 lumens are ideal.



The spacing between lights is also an important factor in choosing high bay LED High Bay lights. There are three most common cases that you can consider to find the best light for your space. These are listed below:


• At 15 feet height, about 12 feet spacing is essential for a bright light. However, if you need normal light, a space of 15 feet should be present.

• At 20 feet high you can go to 15 feet spacing for generating bright light and if you need normal light, a spacing of 18 feet should be used.

• At 30 feet height, you can go for 20 feet spacing between the lights in order to get a brighter light. However, for normal light, you can go for 25 feet spacing.


4.Number of Lights

After you have determined the spacing between the lights, it is now time to know how many lights you are going to need. The number of lights depends on the available space. Using the spacing and the quality of brightness you need, you can know the number of lights you will be needing for a particular space. You can also create a layout to calculate.


5.Type of Lights

High Bay lights are available in a vareity of shapes. We offer both round lights, now known as UFO High Bay Lights and longer larger ones knows as LED Linear High Bay Lights. Most people do not know that round lights spread the lights out just fine if hung a few feet higher up. Above about 15 feet we always recommend round. They are easier to install. In areas with aisles the linear lights become ideal.  At lower heights you can opt for the wide angle style linear high bay lights.


6.How to Calculate Lux? 

Lux is a complicated matter to calculate. You have to make a full CAD plan, (and we do have IES files if needed) however, there are certain simple ways to help you with the calculation without doing Lux.  We can accomplish the goal with other factors the lumens per square foot of the available space as well as height and spacing.  A good number is 2 lumens per cubic foot. If you want bright light, you can go for 3 lumens per cubic foot.


7.Always Get Cross Over Lighting

In order to get better light, you should have light coming from different directions.  This is called cross over lighting.  Ideally we want it from at least 3 locations. The light coming from opposite sides reduces shadows and evens the lighting. As a result, you get better light that avoids the hot spots of bright light you sometimes see . You may have to plan lower lumen fixtures but more of them for better lighting.



Last but not least, you should always look for lumens, not watts. No matter how much watts you choose, if there are not enough lumens, you will not get better light.


These are some factors you need to consider while choosing a high bat LED light bulb. If you are not sure, you can always contact us and we will guide you further.


Sincerely above is helpful for you. Longsun is looking forward to working with you.
