Commercial LED Lighting

Frequently Asked Questions

We asked our new and existing customers the questions they wish they had answered before making their first commercial lighting purchase. If you cannot find the answers you are looking for, please call (888) 423-3191 and a dedicated lighting expert will help you find the right solution.

What Is Commercial Lighting?

Commercial lighting are fixtures that are installed at a commercial location or business. There is some crossover between commercial lighting and industrial lighting in that some fixtures, like high bays, low bays, parking lot fixtures and flood lights, can serve both applications. 

Other institutions, like schools, colleges, ball fields, are also considered commercial lighting applications. Homeowners who would be interested in commercial lighting might have a pole barn, workshop, large garage, horse barn or horse arena they want lit up.

What Voltage Does Commercial Lighting Have?

There are two ranges of voltages that are available in commercial lighting. Actual voltages vary from fixture to fixture, but you typically find 100-277V as the primary range, and 347-480V as the secondary range. These ranges coincide with the multi-tap drivers we supply that automatically adapt to the input voltage detected on the line.

There is no setting up or dial in process you need to do - the drivers will automatically adjust to your incoming voltage. When selecting a fixture, it is important to know what your current voltage input is.

How Much Is Commercial Lighting Fixtures Per Square Foot?

We would first develop a lighting plan that meets your lighting needs, and from there, we can calculate the cost of the fixtures and divide that into the square footage of the space or outdoor area. It stands to reason that a space that is brighter of two spaces will cost more.

What Is the Average Foot Candle of Commercial Lights?

Always start by determining how bright you want the space to be. That is measured in the foot candles floor that you want or by telling us what you will be using the space for. We can then recommend the light level you would require.

Next, the specific fixture that will be used determines the light level that you will get. These two things combined with the actual size of your space can help us determine the right fixture and foot candles on the ground based on a lighting plan. We can run that lighting plan to meet your requirements.

Are Commercial Light Fixtures 120V?

They can be if that is the voltage in your space. If you purchase a commercial light with a 100-277V driver, then it is equipped to handle 120V automatically.

If I Could Supply 120V or 277V to My Fixture, Which Is Better?

First, 120V is safer. So, if your main concern is safety, choose 120V. 

However, the higher voltage you can use, the less amp draw each fixture uses. And on a panel circuit, that can be a concern. You can install more fixtures of the same type on one circuit at 277V than you can at 120V. But, if you can choose, 277VAC provides more advantages.

Remember, most of our standard LED Drivers are 100-277V auto switching. They will adapt to any voltage within that range automatically.

How to Add a Dimmer Switch to Commercial Lighting?

Most of our commercial lights are dimmable, but the dimming system is quite different from the dimming system used in households.

In commercial lighting, there is typically a 0-10V or 1-10V step dimming system that uses a specific isolated dimmer control that is not part of the on-off switch. To support this, you will require 2 low voltage wires run from the switch and daisy chained to each fixture that will be installed on the switch. The fixture must be equipped with a dimmable driver in order to be dimmed.

However, practical applications of dimmable commercial lighting includes, for example, a high bay or low bay fixtures in a warehouse with an attached motion sensor. That motion sensor is smart enough to tell the commercial high bay to dim when the area is vacant. It sends a signal to the dimmable driver to dim. No external switch or extra wiring is required in these installations.

Where Can I Purchase Title 24 Commercial Lighting?

You can find out more here. The light experts at LED Lighting Supply understand Title 24 and Title 20 lighting standards, and we have the commercial fixtures that comply.

How to Install Commercial Light Fixtures?

Commercial lighting fixtures are simple and easy to install for any qualified electrician. They are essentially a 1-for-1 replacement of your existing commercial lighting. They include all the same mounting you are accustomed to and the same wiring that allows you to easily connect to your existing conjunction boxes or lighting infrastructure.

How Is Commercial Lighting Wired?

Typically, you are only dealing with 3 wires - line, neutral and ground. This wiring is simple and easy to deal with. However, it’s always best to hire a licensed electrician.
