​​Commercial and industrial facilities all over the country are realizing that switching to LED lighting can greatly reduce their energy costs and improve employee efficiency.

And, between the increasing cost of electricity and the negative impact of greenhouse gas emissions, many businesses everywhere across the globe are adopting energy-efficient and environmentally practices. The quickest and easiest way to do this is to switch to LED lighting.

​​It is no secret that LED lights have revolutionized lighting thanks to their low energy consumption, reduced maintenance, high light output, and a myriad of other excellent benefits.

These lights have helped businesses, organizations, and institutions to save a great deal of money on electricity and cooling costs. However, the unique needs of some of these facilities have business owners wondering, can LED lights replace what they’ve been relying on for decades?

​​The short answer is yes. LED lights are the most versatile lighting method on the market. With everything from explosion-proof and vapor tight fixtures to exit signs and panel lights, there’s an LED lighting solution for every setting.

One of these challenging, but familiar settings, is large spaces with high ceilings. Most lights don’t have the power to reach the ground and provide bright light. But, that’s not a problem for LED High Bays.

How Do The High Bay Lights Work?

​​You’ve probably seen LED High Bay Lighting before and never even noticed them. Typically they are found in manufacturing facilities, warehouses, factories, gymnasiums, and even large department stores.

High bay LED lights are designed to illuminate large spaces with ceilings between 20 and 45 feet tall. These powerful lights provide just the right amount of light for large spaces with high ceilings.

The light fixtures can be either attached to ceilings via chains, hooks, or pendants, or they can be attached directly to the ceiling itself. This decision depends on the facility and what the operators are looking to get out of the light.

​​Like all LED lighting, LED High Bays are available in a wide range of different styles. Each one designed to fulfill a different purpose. To the laymen, they may all look the same. But, pull back the curtain, and you’ll find that these lights are actually quite unique. And, that’s exactly what we intend to do, pull back the curtain on High Bays.


What Makes LED High Bays the Perfect Choice?

1. LED’s have become more Affordable

At first, business owners hesitated in buying the LED lights because these lights were new and unknown, and expensive. 

However, the this has all changed now and the prices of LEDs have gone down to make them preferable and affordable to almost all the business and facility owners.

More than the affordable initial price, LEDs promote higher savings over the long run too. Their energy consumption and heat generation is much lower than the other conventional HID fixtures.

LEDs help you save more on the power bills as they consume less power than the lights they are designed to replace.

2. LED High Bays Provide High Quality Lighting

Looks of the facility do matter for their owners. Thus, they look for those industrial and commercial lighting systems that can amp up the facility’s appearance too.

The sleek and modern look of the LED high bay fixtures along with the bright light they produce boosts the looks of any setting instantly. The white and bright light of LEDs makes the objects under them appear better and true to their colors. This is known as CRI, or quality of light. Bright high quality light makes for a safer work and retail environment.

3. LED’s Lower Energy Consumption

We did sat that LEDs save energy but the facts further will surprise you even more. Its not unreasonable to expect a energy savings of 50% or more over using conventional light sources, like Metal Halide or fluorescent lights. LEDs are 50% more energy-efficient than fluorescent bulbs and at least 60% more efficient than Metal Halide. 

To increase the savings, combining the LED high bays with lighting controls would be good.

4. LED’s Lower Maintenance Costs

Fluorescent lights were used in commercial and industrial spaces before LEDs. This was so because they had almost zero warm-up time, and bulbs lasted for as much as 10000 hours. Of the other conventional lighting, they required the least maintenance out of all.

However, a life of 10,000 hours is too low for current lighting demands. LED lights changed the lighting standards with an average lifespan of about 50,000 or more hours. It is not hard to imagine a LED High bay last 10+ years being used 12 hours a day.

Other benefits of LEDs include:

slow lumen degradation

high durability

easy handling

12 Tips on How to Pick the Best LED High Bay

1. Prepare a Layout of the area

The first thing before buying LED high bays is to create a lighting plan. This is because different spaces need different types of lights. For instance, a storage room may only need a light with 30 foot candles. A large warehouse might need 50 foot candles. Assembly areas need more, 70+ foot candles.

Spaces like retail stores need very bright, high quality light so that shoppers can clearly see the products they’re buying (80 foot candles or more).

Creating a lighting plan is perhaps the most important thing you can do. It will dictate the rest of your lighting decisions and ensure that you get the lights you need and nothing else.

How many LED High Bay Lights do you need?

The most accurate way to determine this is to create a high bay lighting plan.

A high bay lighting plan will show how bright your indoor space can be and how evenly the light will be distributed. It will also show you the locations of the lights. We can create a custom high bay lighting plan for your indoor area for Free. 

This takes the risk out of your LED purchase.

We have done 1000’s of FREE lighting plans. We have 100’s of lights to choose from to meet almost any requirement or budget.  We have a warehouse full of LED lights ready to ship.  So your lighting plan to purchase can be a quick and easy.

2. Determine The Watts And Lumen Levels

This is arguably the hardest part of the decision. What is the LED High Bay do you need, and how many watts will it use?  Most buyers start by selecting a high bay based on its watts used. This is actually a bad idea.

The proper way is to figure out how many lumens you need, and then find the light that produces those lumens most efficiently. 

Still, its hard to figure out how many lumens you need until you understand the foot candles you need to light up the area. 

So how can you possibly make the right decision? Watts? Lumens? Foot candles?

Fortunately there is an easy button. A lighting plan will figure this all our for you. Its a simple process that starts by knowing the dimensions of the rooms, lighting height and locations and desired foot candles. The software does the rest. To start, here is a simple lumens guide per light based on mounting height. 

Bulbs at 10-15 feet height must produce 10000-15000 lumens

Bulbs at 15-20 feet height must produce 16000-25000 lumens

Bulbs at 25-35 feet height must produce 36000 lumens or more

 3. Determine The Number Of Lights You Need For The Area

This is where our photometric lighting plan really shines. Using the layout of your facility and by determining the number of lumens you want or need, it will tell you exactly how many lights you should have and how far apart they should be.

This helps save you money on installation costs and prevents you from running unnecessary fixtures. A lighting plan will determine how many lights you need and where they should be spaced. It even works with existing lighting schemes.

4. Decide on the Type of High Bay Light that fits your need

We mentioned the great variety range of high bays above. The variety makes them adaptable for different settings but you may face difficulty in picking the right light for your facility.

The two major types of high bays are linear high bays (panel style lights that replace fluorescent fixtures) and UFOs (round, robust, compact lights).

Linear high bays can perfectly replace the fluorescent lights in bigger spaces. UFO high bays are also perfect for high ceilings but are more robust than linear fixtures and most are IP (wet) rated.

High bays also come as wide-angled linear lights that work best for spaces with low height ceilings. 

UFO LED High Bays

These are sturdy, small, and circular high bay lights. UFOs can be a great replacement for all other conventional high bays like Metal Halides, High-Pressure Sodium, and HIDs.

UFOs can be the best option to go with if you want lights for warehouses and gyms. They are also good for the locations vulnerable to dampness since they are typically IP65+ rated.

Decide on Efficacy Standards

Efficacy is measurement of how well a LED converts electricity into light. With LED’s, efficacy refers to lumens per watt, or how much energy the fixture needs to consume to produce a certain amount of visible light.

The higher a LED lights efficacy, the fewer watts a high bay consumes to produce the same amount of lumens.

How important is efficacy, or lumens per watt, to you? LED High bays with a lower efficacy will typically cost less to purchase but will consume more energy over the lifetime of the light. This means that you will have a higher lighting bill. Over the lifetime of the fixture, a high efficacy light will save you a lot more money.

​​A 100 Watt LED High Bay at 150 lumens / watt produces 15,000 lumens.

​​A 150 Watt LED High Bay at 100 lumens / watt also produces 15,000 lumens.

​For each hour both lights operate, the more efficient 100 Watt light consumes 50 fewer watts. This is real energy savings.

​More efficient lights typically cost a bit more at the time of purchase. But they will save you a lot more money in reduced lighting bills over the life of the high bay.

6. Do you need a  high voltage high bay?

The typical voltage range in most commercial and industrial indoor spaces ranges between 100 and 480 volts. LED High Bays can accommodate these areas and offer several drivers. These drivers switch to the incoming voltage automatically, so there is no need to adjust the high bays during installation. The common LED Driver voltage ranges are:




7. How to determine the right color temperature?

This can be a difficult decision. Color temperature is measured by the Kelvins scale where a high number represents yellow-warm light and a low number represents blue-cool light.

3000K is best for home lighting.

6000K light isn’t preferred by most due to the harsh blue brightness it generates.

4000K high bay light will be good option for creating a warm and welcoming ambiance.

We would recommend a 5000K light as the best replacement for metal halide lights if you are opting for LED conversion.

Color Temperature Bulbs

​​The two most common color temperatures for high bay applications are:

​4000K – or Warm White
​​5000K – or Day White

8. How to determine the suitable CRI?

CRI is the abbreviation for Color Rendering Index. It is the measurement of the real quality of the light produced by any light source.

High bay lights for the commercial and industrial application must have a CRI of 70 or above.

On the other hand, a CRI of 80-90 will be good for the spaces that see manufacturing activities as they need better color rendering.

Higher CRI means lower lumen need.

9. Determine light distribution levels

Just like optimal lighting levels are important for any space, even lighting distribution is important too. This becomes even more crucial for indoor lighting since every corner of the space must be lit alike. 

Proper lighting distribution can be determined with a lighting plan. Our high bay lighting plans will make you able to go ahead with error-free lighting.

10. Using right light controls with High Bay LEDs 

Light controls facilitate the automation of light capacity and power on/off handling. While choosing from the various dimming controls available for LED high bays, motion sensors are the best option for indoor lights. 

PIR and Microwave are two major types of motion sensor controls. 

Microwave sensors work best at detecting common movements in big spaces.

PIR or Passive Infrared sensors use infrared beams for detecting movements in target areas.

While the industrial-commercial facilities make use of microwave sensors, the smaller facilities or areas use PIR sensors.

A 0-10V dimmable driver must be installed in your LED high bay. These drivers allow motion sensors to automate low light levels. Without them, you can only control on/off.

In these drivers, 0V doesn’t mean power off. It typical dims the light to 10% at 0 setting,

11. High ambient temperatures?

You need to also decide if you would want high-temperature resistant lights for your facility. Most high bay lights are rated resistant to around 122 degrees F. If your facility gets hotter than that, then you should look into a high temperature high bay. We provide High-Temperature High Bays rated for 176-194 degrees F.

12. High bay lights for high impact

The bigger spaces like manufacturing facilities and warehouses are more vulnerable to facing high impact clashes on their light fixtures. This raises the need for solid and impact resistance lights for such areas.

The impact resistance with the performance retaining ability of any light is represented by IK ratings.

IK ratings range from IK01 to IK10 where IK10 denotes the strongest lights.

Thus, if you have any such spaces where the lights are prone to any accidental impact like gyms go with the IK08+ rated lights.

What is a high bay light?

 A space with high ceilings is called High Bay. These Bay areas have ceilings with a height of 20 feet or more. The light installed in the indoor bays is called the High Bay light. These lights are meant to illuminate the surface and workspace from the 20 feet or higher ceiling mounts.

What are the best high bay LED lights?

This can’t have one answer. The best light will be different for every customer as per its need. Every area has different lighting needs. There might be a condition that would require the installation of any particular fixture. This depends upon mounting height, heat, distribution, and lighting levels. We offer the best help for choosing the right high bay LED solutions. Take our guidance for the purpose!

How many high bay lights do I need?

A lighting plan can be the best answer for all facility lighting needs. This plan builds a software lighting layout according to the dimensions and other factors of the target space. We test the plan with current lighting models and locations afterward.

Are lighting plans crucial? It depends on how well you want to understand the lighting needs of your space and purchase LED lighting without any risk. We base our guidance and information on the results we get after custom testing our lights. We want you to use LEDs and save more! However, we also want to ensure that you choose the right light.
