9 Steps to Choosing the Best Warehouse Lighting


1. Decide the right efficacy (lumens/watt) to maximize saving in your warehouse.

No, we did not misspell efficiency. Efficacy is defined as the ability to produce a desired result. In relation to LED lighting specifically, efficacy is a light’s ability to deliver a certain amount of lumens per watt. The higher a LED warehouse lights efficacy, the fewer watts a warehouse light consumes to produce the same amount of lumens.

A 150W LED High Bay at 150 lumens/watt produces 22,500 lumens.

A 200W LED High Bay at 112.5 lumens/watt also produces 22,500 lumens.

For each hour both lights operate, the more efficient 150W 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 warehouse lighting bills over the life of the fixture.

The trade-off: Lower cost as the initial purchase versus a lifetime of savings.

The verdict: The more efficient light will always pay itself off many times over its life.

2. What type of Warehouse LED Lights Do I Need?

UFO and Linear High Bays are two of the most common types of warehouse lighting. Every setting is different, and so are its lighting needs, but chances are, you’ll require at least one of these two lights for your warehouse.

Warehouse Light

LED UFO Round Warehouse Lights are round, compact, and rugged. They’re designed to replace both low & high bay HIDs, Metal Halide fixtures, and High-Pressure Sodium high bays.

They’re IP rated for wet locations, so if they happen to get wet, you don’t have to worry about the light being compromised. And, they are smaller and more compact than their linear fixture counterparts.

LED Linear High Bays replace T5 and T8 tube-style fluorescent high bays. They’re great options for LED warehouse lights if you want a look that’s similar to your existing fixtures.  These high bay lights have a low profile.

And because they’re panel style with linear led strips, LED linear high bays offer great light distribution. They are much larger than UFO lights and are usually recommended for indoor use.

3. How many LED watts do you need to replace Metal Halide / Fluorescent Lights?

This is a tricky question because LEDs are much more efficient than other types of lighting. Watts are a measurement of the amount of energy consumed, and because LEDs use less energy to produce the same amount of light, you can’t just swap one out for the other.


General Guidelines for converting to LED wattage

250 Watt Metal Halide, you should choose between 10,000 to 12,000 LED Lumens
400 Watt Metal Halide, you should choose between 15,000 to 25,000 LED Lumens
1000 Watt Metal Halide, you should choose between 36,000 to 55,000 LED Lumens
4 tube F54T5HO, you should choose between 10,000 to 12,000 LED Lumens
6 tube F54T5HO, you should choose between 15,000 to 25,000 LED Lumens
8 tube F54T5HO, you should choose between 36,000 to 55,000 LED Lumens

4. Do you need high voltage fixtures?

LED warehouse lights have these common voltage ranges:

100-277 Volts (most popular)
277-480 Volts
347-480 Volts (for Canada)

LED warehouse lights don’t need manual voltage adjustment as they do it themselves as per the incoming voltage. However, you must purchase warehouse lights only according to the correct voltage.  

5. Determine the Brightness Your Warehouse Needs

As we said earlier, every warehouse setting is different. And, although you may not be aware of it, your warehouse’s ceiling and walls can have an impact on the illumination. Walls and ceilings with light colors like white and cream reflect light, decreasing the number of lumens a space needs.

While darker colors, on the other hand, absorb light and require more lumens. The fewer watts the light uses, the more savings you’ll experience. So if you have generally well-lit space with access to daylight, switching to low-wattage LEDs can and will significantly reduce your warehouse’s energy consumption.  

6. Pick the Right Color Temperature

Light color temperature is often dismissed as an unchangeable aspect of the light. But, with LED lighting, you have complete control over the color temperature of your light. Why is it important to choose the right color temperature?

Because color temperature dictates how people see objects and also affects mood and productivity. It is usually measured in Kelvins and describes the color characteristics of a light source (warm, cool, bright, natural, daylight, etc.).

The two most common color temperatures are:

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

These are by far the most common options used in today’s warehouse conversions to LED. For those who like the bright white of Metal Halide, then 5000K would be your option. If you’re looking for a slightly warmer light, then 4000K should be a consideration.

7. What CRI Do You Need for Warehouse Light?

First and foremost, CRI refers to the Color Rendering Index which grades a light based on its quality. Light quality is extremely important because it directly affects how well people see and how they discern color. So what is the ideal CRI for warehouse lighting?

Well, it all depends on what type of warehouse you have. 90%+ of all warehouses will be fine with 70 CRI LED Lights. However, in a setting where color differentiation is an important part of everyday tasks, we recommend a higher CRI, somewhere between 80-95.

Switching to LEDs is likely an upgrade in CRI, regardless of their score, because the light they produce is higher quality than the light from HPS, Metal Halide, and fluorescent sources. Just converting to LEDs can greatly improve the light quality in any warehouse.

8. What About Light Distribution in Warehouses?

Little known fact: light distribution is just as important as light levels. It’s important to be knowledgeable about your facility’s light distribution to get the best possible results from your lights.  There are many different options to consider for warehouse lighting, and choosing the right optic can mean the difference between good and great lighting. In fact, in some cases, choosing no optic is the best choice.

So how can you determine your ideal light distribution before you purchase new lights? That’s easy, get a photometric light plan. A photometric light plan will help you understand how well the light is distributed throughout an entire area.

It will also help you predict shadows and bright spots, and aid in your goal of achieving even light distribution. It will even let you know if you need to add optics to narrow down the beam angles in the case of high ceiling heights or warehouse rack rows. And, it will help you plan out where and how to install task lighting. The best way to prepare for converting to LED lighting is to use a photometric lighting plan.

9. Occupancy Sensors and Dimming

Although many different settings benefit from motion sensors and dimming controls, there are few that are affected more than warehouses. Warehouses are extremely large spaces, with many areas that are not often occupied or in use.

Occupancy sensors and dimming controls do away with the need to switch lights on and off every time you come and go, saving you time and money. In fact, by using your warehouse lights only when necessary, you could cut energy costs by up to 30%. 

If you want your motion sensor to dim the fixture, you need a 0-10V dimmable LED driver. If you are ok with just On-Off, the driver does not need to be dimmable.

0-10V drivers – 0V doesn’t always mean off. It can sometimes mean 10% on. Ask an LED lighting expert about your specific fixture before purchasing.

10. How much will you save when you convert to LED?

Here is the costs savings you can expect if you convert your 400W HID  light source over to LED. In the table below, we show the savings per fixture for every fixture converted over per year. It assumes a run rate of 12 hours per day. We chose a 150W LED Fixture, but what you need may be less than this.

Here is the costs savings you can expect if you convert your 1000W HID equivalent lights over to LED.

In the table below, we show the savings per fixture for every fixture converted over per year. It assumes a run rate of 12 hours per day. We chose a 320W LED Fixture for this example.

Frequently Asked Questions: LED Warehouse Lights 

1. What are Warehouse lights?

LED Warehouse lights are typically high bay and low bay fixtures, depending on the height of the ceiling. For warehouse ceiling heights 20 feet or lower, you should consider a lower powered low bay light. For warehouse ceiling heights 20 feet or above, you should consider using a LED High Bay fixture.

2. What are the best LED Lights for Warehouses and Distribution Centers?

The Best LED High Bay Warehouse Light may be different for each warehouse building. The "Best LED Warehouse Light" is the one that provides the provides a well lit area and does it efficiently to lower your utility bill. A warehouse high bay that is best for one location may not be your best option.

A good way to discover what is the best warehouse light is to create a warehouse lighting plan. LED Lighting Supply offers free Warehouse Lighting Plans to help you find the Best Warehouse Light for your conditions.

3. How many Warehouse Lights do you need?

The best way to calculate this is to create a warehouse / distribution center lighting plan. A warehouse lighting plan models your indoor building in software and creates a visual report including light locations, foot candle readings, and how well the light is distributed. Different models of high bay led warehouse lights can be tested until the right light that offers the proper light levels and balance is determined.

4. What are the best LED lights to replace Metal Halide Warehouse Lights?

You should consider round style LED UFO High Bays to replace Metal Halide High Bays inside a warehouse. LED Light Supply has UFO High Bay fixtures specifically designed to replace 250 Watt, 400 Watt and 1000 Watt Metal Halide High bays (Metal Halide is also referred to as High Intensity Discharge, or HID, lights. High Pressure Sodium Bulbs are also a member of this family). These UFO LED High Bays are very robust, compact, super bright and will consume 50%-90%* less energy than Metal Halides. You can also expect LED High Bays to last much longer than Metal Halide Lamps.

* Higher energy savings can occur when LED High Bays are married with Lighting Controls like motion sensors

5. What are the best LED lights to replace Fluorescent T5 / T8 Warehouse Lights?

You should consider panel style LED Linear High Bays to replace fluorescent inside a warehouse. LED Light Supply has Linear High Bay LED Lights specifically designed to replace 4 tube, 6 tube and 8 tube T5 and T8 Fluorescent High bays. We do not recommend replacing fluorescent tubes with LED tube lights - the cost differential is minimal and LED Linear High Bay Lighting is far more robust and durable.

6. What are LED Warehouse Lighting High Bays?

These are high bays that work well in the different operations of a working commercial warehouse facility. There are high bay led light fixtures designed to work in open areas, general task areas, assembly areas as well as racking locations. They can replace both 400 Watt and 1000 Watt Metal Halide High Bays as well as high output T5 tube fixtures. They have high voltage capabilities.
