LED High Bay Replacement

7 Reasons to Convert to LED High Bay Lighting

1. LED High Bays reduce costs by 75% over HID High Bays

Reducing commercial high bay lighting costs becomes practical and sustainable with our energy efficient indoor high bay lights. With energy savings up to 75%, you can reduce a tremendous amount of energy consumption.  Also save with LED high bays via longer lifespans, reduced maintenance costs, motion sensors, dimmable high bay lighting options, and even rebates.


2. High Bay LED Lighting will decrease maintenance costs

Our efficient LED high bay lights are L70 rated last upwards of 100,000+ hours. This allows for less replacements of your bay fixtures, which is costly in applications such as a factory or warehouse where high bay lights are used due to the extreme heights they are installed at. This cost saver of LED high bay light fixtures is often overlooked, but saves a tremendous amount of money.


3. LED High Bay Lights are rugged fixtures that will last years!

Our industrial high bay LED light fixtures are able to withstand extreme cold and hot temperatures (all the way up to 190F), without decreasing its lifespan. This is possible through our large heat sinks, specially designed to keep the lights cool. Our quality LED high bay fixtures are also vibration resistant, allowing them to maintain a long lifespan in harsher environments, perfect for commercial & industrial environments requiring industrial high bay LED lighting fixtures.

4. 480V LED High Bay

Are you trying to replace high bay fixtures that are 277V? 347V? 480V? We have solutions that cover these higher voltage installations. Our constant current drivers are equipped to handle everything from 100 Volts up to to 480 Volts (standard driver in our kits are 100V-277V). We can handle single or 3-phase power as well. Talk to our sales engineers and we can get your lighting situation taken care of.



MyLEDLightingGuide Pro Tip

480V for LED High Bays

Our higher voltage solutions can handle both single phase and 3 phase 480V installations. If you have a voltage above 277V, make sure you tell our sales engineers so we can specify the proper driver in your led high bay.

5. Easily convert F54T5HO over to LED

Tired of changing tubes? Tired of tubes that don't last as long as they should? Replacing F54T5HO Fluorescent fixtures is simple and easy. Each T5 tube produces approximately 4000 lumens each. The light is not directional, so effective lumens is actually less than the 24000 combined lumens for a 6 tube fixture. We can easily replace these fixtures with a cost effective, maintenance free equivalent LED solution.


6. High Temperature High Bay Options for hot environments

Have a hot environment? We have LED High Bay Lights that are rated for ambient temperatures for 60C, 70C, 80C and even 90C. These lights are engineered to last, and many of them can be configured to be either installed as a high bay or a flood light.

7. Wet Location LED High Bays

Many of our commercial LED high bay fixtures are designed with an IP rating. IP (Ingress Protection) is a rating system that determines how well a fixture can keep out dust and moisture. It is represented as IPXX, where the first digit is how well it keeps out dust and the second digit talks about how well it keeps out water.

We have a line of Commercial High Bay fixtures & products that are rated IP65, IP66 and IP67. How much do you need? Typically IP65 LED high bay is all that is required unless you have an environment where strong pressurized water is being directly sprayed on to the bay fixtures. They can even be used outdoors.


MyLEDLightingGuide Pro Tip

What IP Rating do you need?

Typically, IP65 is all you will need. If you have more extreme environments, such as wash downs with high pressure water, than consider IP67 or higher.

LED High Bay Types

UFO LED High Bays - Round LED High Bays 

When selecting light fixtures for high bay applications, the most important thing is efficiency. Since the light fixtures will light up space from a high point, the light must be optimized for illumination. UFO high bays have a very unique design that plays a crucial role in their efficiency. Their massive UFO style heat sink ensures they transfer thermal properties more evenly and efficiently. Models are available to replace 250W, 400W and 1000W HID. MyLEDLightingGuide have models that return close to 100, 000 lumens of powerful, directed LED Light to the work surface below.

Linear LED High Bays

Panel style Linear LED high bays have a look that is similar to that of troffer-style panels; they look like T8 and T5 fluorescent fixtures. Models are available to replace 250W to 1000W Metal Halide or  F54T5HO or F32T8 tube lamps fixtures/

Their major benefit is that they have the ability to distribute light over a large area, so you may need fewer light fixtures to sufficiently illuminate your space. These fixtures also have large heat sinks which excellently dissipate the heat their LEDs produce.

LED Retrofit Bulbs for HID High Bays

For those who want to switch to LED technology and also save money, this is the best option. A High Bay retrofit kit is usually installed in the existing traditional light fixture and the conventional bulb and ballast are replaced with a LED head and driver. Retrofit units can be more affordable than new LED high bay light fixtures because they are cheaper to manufacture – they have fewer components. They are also cheaper to install as their installation process is not complicated.

Why Are LED High Bays Superior to Metal Halide and Fluorescent High Bays?

Better Lumen Intensity

The modernization of today's light source has created a considerable improvement in energy efficiency. Thanks to the innovative  technologies in the lighting industry, such as the use of LED, and controls that work with these lights, lighting products are now more efficient and energy consumption has gone down substantially. This translates into a large reduction in the cost of lighting.

Allow us to take a little time to explain in detail how LEDs have better lumen intensity than HID lamps (which are used in some high bay lighting applications).

1. Initial Lumens

The truth of the matter is that all light sources fade over time, no matter the technology. What happens is that light intensity diminishes to the extent it becomes inefficient. This does not mean the light has failed, it just means that the usefulness of the light has diminished significantly. When a lighting fixture is installed in an application and it is switched on, its luminosity is highest at that point. This is called the initial lumens. The initial lumens for LED lights are usually measured 45 minutes after the lights are switched on as the LED diodes need time to stabilize. When it comes to HID light bulb, the initial lumens are calculated after 1,000 hours of initial use.

2. Lumen Maintenance and L50, L70 and L90 Rating

Lumen maintenance is related to the lifespan of a light source. LED lights do not burn out like traditional lighting systems. Rather, they continue working as long as there is an electrical current . What happens is that the light intensity fades gradually, rendering the luminaries obsolete and inefficient.

For LED lighting products L50, L70, and L90 are used to calculate the lifespan of a LED diodes circuit board in hourly increments. Lighting experts use these ratings to estimate the amount of light the LED diodes produce when the fixtures diffuse 50% (L50), 70% (L70) or 90% (L90) of the number of initial lumens.

The L70 rating is the most popular and is used to indicate the point at which LED lighting products will lose 30% of their lumen intensity (and maintain 70%). So when you look at the specifications of a LED product, the total life of the product may vary from the L70 lifetime established for the LED themselves. Other components may fail before the LED's hit their L70 life. However, these components, in well designed LED products, can be replaced (easily).

A 70% deterioration in light output corresponds with the point at which the human eye notices a decline in the intensity of light. However, the human eye is only negatively affected when the light intensity of a light source reaches a level of 30%.

So, when a luminaire manufacturer states that a luminaire has a 50,000 hour lumen maintenance, it usually means that we will only notice a decrease in light intensity after the light source has been in use for 50,000 hours. But you should not take this to mean that the luminaire will stop functioning.

3. Delivered Lumens

The term delivered lumens (absolute lumens) usually describes the luminous flux produced by a light source when its optical loss factor is taken into account. When it comes to traditional HID High Bay lighting technology, only the light intensity of the lamps is measured, the optical loss is not included in the calculation. Including delivered lumens is very important, because HID lamps do not deliver the same amount of lumens they produce. This is key when you compare the specification of an HID High Bay and a LED High Bay because what you think you get with an HID High Bay is not what appears to be advertised.

But when it comes to LEDs, the story is different. When LED luminaires are being tested, the optical loss factor is usually taken into account. So, in the case of LEDs, we actually refer to the delivered lumens when we talk about their light intensity.

When comparing the light output of an HID lamp with that of a LED lamp, a variety of factors must be examined. These include the lifespan of the light sources, the optical loss factor (particularly for high intensity discharge light sources), and the lumen maintenance over time.

In a nutshell, when the luminous flux of HID lamps and LED lamps used in High Bays and other fixtures are compared, LEDs are observed to have much better light intensity. Measuring the luminous flux of a light source helps us to know its efficiency. This way, we can choose the one with a higher number of delivered lumens – which is always LED.

Things to Consider when Choosing a LED High Bay

1. Luminous Efficacy (Lumens Per Watt)

Luminous efficacy is the true measure of a bulb’s efficiency. It indicates the lumens produced for every watt of electricity consumed. LED bulbs are more efficient than traditional bulbs as they have a higher luminous efficacy. High quality LEDs have awesome efficacy ratings; the standard luminous efficacy is currently 100 lumens per watt. This means that a good LED bulb should produce 100 lumens for every watt of energy it draws.

Think of luminous efficacy as bang for the buck. The efficiency of your new LED high bay lights will be seen in the reduction of your electric bill as utilities charge by the watt. If you get LED high bays with a high luminous efficacy, they will pay for themselves very quickly.


MyLEDLightingGuide Pro Tip

The trade off between initial cost and long term savings?

A higher efficiency LED product typically costs more than lower efficiency units. But over the life of the product, the savings will be many times more than the smaller initial investment needed to upgrade to the higher efficiency LED chips. So if you are looking to maximize your savings when converting to LED, choose the higher efficiency product.

2. Color Temperature


Color temperature, which is also known as correlated color temperature, accurately measures the temperature of a light source. The Kelvin scale is used to measure a bulb's color temperature because of its accuracy in measuring very hot and cold objects. Bulbs with a low color temperature produce warm light (in the red, orange, and yellow spectrum) while those with a high color temperature produce cool light (in blue and white spectrum).

HID and fluorescent lamps generate light in different colors, however, the color range is limited. On the contrary, LEDs produce light in a wide range of colors. The standard color temperature for industrial and commercial spaces is between 4000K and 5500K. Spaces that need very bright light – like factories, warehouses and assembly lines – need lights with a color temperature of 5000K. 



MyLEDLightingGuide Pro Tip

 LED High Bay Color Choices

To replace Metal Halide, 5000K is a great color choice. If you would like a slightly warmer light, choose 4000K. While rare, HPS high bays are typically 2300K. Moving to 5000K will greatly improve the lighting indoors.

3. High Bay Light Quality: Color Rendering Index

Color rendering index defines the color of light and tells us how well a light source will reveal the colors of items compared to sunlight (the ideal light source). When it comes to high intensity discharge lamps, people usually complain about one thing: poor light color. Light color is extremely important in low bay applications because it has a huge impact on clarity and contrast.

Most high bay applications require a high level of illumination for work to be done well and productivity to increase. Powerful lighting helps maintain the proper foot candle levels for adequate illumination. If these levels are not maintained, accidents may occur.


MyLEDLightingGuide Pro Tip

LED High Bay CRI

Typically, anything over 70 is good. For assembly work, fine detail where color representation is necessary, then select 80 to 90 CRI.

4. The Beam Angle

The beam angle is what determines how light will be distributed. A wide beam angle produces general, softer light and distributes the light better to different areas of a room. A narrow beam angle produces concentrated light which is good for accent lighting, it makes the light more intense and focused. LED lights are available in a range of beam angles: from 15° (narrow) to 120° (wide). Choosing the right beam angles can greatly improve the lighting in a high bay application. With LED, you won't need a reflector to gather the light and direct it to the ground, like you would when using a Metal Halide High Bay fixture.


MyLEDLightingGuide Pro Tip

LED High Bay Beam Angle Selection

Ask us to run a lighting photometric to determine the perfect light and the perfect beam angle for your indoor space. Look at both the foot candle measurements and max/min ratios to make sure your space is bright and the light is uniform.

5. The Warranty

A good quality indicator of LED high bay lights is their warranty. Reputable LED manufacturers always honor their warranties, provided they are valid. When checking the warranty, be sure to check the warranty for the LED head and the driver as they may be listed separately. 

High-quality LED high bay lights usually have a 5 to 10 year warranty. Most manufacturers give a 5 year warranty for the LED drivers – which is the industry standard.

Do not be tempted to buy low quality LED high bays as they may soon malfunction, forcing you to spend money on new light fixtures. Your business activities will also be disrupted by poor lighting or light replacement.
