Discover how smart lighting solutions and PoE are revolutionizing how we approach commercial and residential lighting applications

Smart lighting applications are a huge topic of discussion when it comes to smart technology in both commercial and residential properties.

One of the most common ways that developers are introducing smart lighting solutions into new builds is through PoE technology.

It doesn’t matter whether it is a new build or a renovation, all lighting projects can benefit from power over Ethernet lighting (PoE).

That’s why today we’re going to be looking at the 3 key advantages of PoE lighting over traditional, high voltage lighting setups to show how Ethernet cables are changing the lighting industry. Let’s get started!

How Does POE Lighting Work?

Lighting via Ethernet cables creates safer and smarter lighting solutions

Previously only used for internet connection, Ethernet cables are now critical for lighting applications.

When we talk about POE lighting, we are referring to any lighting application that uses Ethernet cables instead of high voltage electric cables. Previously, Ethernet cables were used exclusively to connect to the internet and were unable to power devices because they were unable to transmit the optimum level of electricity.

Since lower voltage LEDs have become the preferred lighting method over fluorescent or incandescent bulbs, Ethernet cords are now able to transmit enough energy to power large-scale lighting applications.

Not only that, but PoE lighting retains the same capabilities from its previous use—that is to say that PoE setups can simultaneously transmit electricity and information to your building management system (BMS).

Now that we’ve discussed how PoE lighting works, let’s get into some of the advantages of these smart lighting solutions.

PoE Lighting Saves Money and Energy

From installation to energy costs, PoE smart lighting solutions help cut costs

Precise controls and reporting allow for big energy savings.

When you choose to install PoE smart lighting solutions, then you can expect major savings beginning with the installation process. As we previously mentioned, Ethernet cables can transmit electricity at a far lower voltage than other lighting methods. Most PoE systems operate with a voltage under 60V.

This means that electricians will not need a conduit or metal cladding to get the job done. In this case, the lower the risk associated with installation, the lower the total installation cost.

Beyond installation, PoE lighting solutions cut down on monthly energy costs because they require less energy to power the same amount of light.

That’s right, even though LEDs require far less energy, you don’t have to sacrifice brightness or quality to save energy.

PoE Lighting Optimizes Lighting Operations

Since PoE can transmit data, it can help you access invaluable information on energy use

Ethernet cords move energy and data simultaneously.

Because electricity and information can easily and simultaneously travel along Ethernet cords, you can use the data to improve your operations.

Whether you’re a homeowner searching for a low-cost way to light the exterior of your home or a business owner interested in lighting a large commercial space, you stand to benefit from data pulled by smart lighting solutions.

By accessing this data, you can better understand and control your lighting to save even more energy and make sure that your lighting profile is ideal for all inhabitants.

For large commercial lighting applications, your LED lighting will send data that is collected on the BMS.

The BMS will then provide suggestions for improvement regarding energy output, making sure that you are never wasting energy on unnecessary lighting.

PoE Lighting Allows for Far Greater Lighting Control

Older lighting solutions don’t compare to PoE smart lighting solutions when it comes to performance

PoE lighting can automatically communicate with light sensors and your BMS.

In addition to the ability to transmit data and save energy by operating at a lower voltage, PoE lighting also provides exceptional control.

By using PoE to light your commercial or residential property, you now have access to lighting options that were previously impossible using fluorescent or incandescent light bulbs.

Without changing any physical element of your lighting setup, you can remotely alter lighting quality, brightness, hue, and color.

Using your BMS, you can pre-program different lighting commands and even integrate sensors as a part of your smart lighting solutions.

Using sensors, you can program your lighting to adjust to outdoor sunlight levels. Using sensors, no matter the time of day or weather conditions, your indoor lighting will always remain at the ideal brightness, hue, and color based on data collected by the sensors.

If you haven’t previously considered PoE lighting for your commercial or residential property, now is the time to start exploring this type of lighting technology.

Smart lighting solutions are the way of the future and outdated lighting systems are quickly being replaced by their more efficient counterparts.

For money-saving opportunities, low installation costs, machine learning, and superior lighting control, PoE lighting is the way to go.

Frequently Asked Question

What is the downside PoE?

The downside of Power over Ethernet (PoE) primarily revolves around its limitations and potential for complications. Here are a few key points:

  • Distance Limitation: PoE has a distance limitation of 100 meters (328 feet), which can be a constraint for larger networks.
  • Power Limitation: PoE can only deliver a limited amount of power, which may not be sufficient for some high-power devices.
  • Infrastructure Upgrade: Existing non-PoE networks may require a significant infrastructure upgrade, including new switches and cabling.
  • Heat Generation: PoE devices can generate heat, which can affect the performance and lifespan of the network cables if not properly managed.
  • Compatibility Issues: Not all devices are PoE-compatible, which can limit the types of devices that can be used on the network.

What is power over ethernet lighting pros and cons?

Power over Ethernet (PoE) lighting has several advantages and disadvantages:


  • Energy Efficiency: PoE lighting is highly energy-efficient, which can lead to significant cost savings over time.
  • Easy Installation and Management: PoE lighting systems are easy to install and manage, as they require only one cable for both power and data.
  • Flexibility: PoE lighting allows for greater flexibility in terms of where lights can be placed, as they do not require proximity to an electrical outlet.
  • Smart Control: PoE lighting can be integrated with smart control systems for advanced features like remote control, scheduling, and automation.


  • Power Limitation: PoE lighting systems can only deliver a limited amount of power, which may not be sufficient for some high-power lighting applications.
  • Distance Limitation: PoE has a distance limitation of 100 meters (328 feet), which can be a constraint for larger installations.
  • Infrastructure Upgrade: Existing non-PoE networks may require a significant infrastructure upgrade, including new switches and cabling.
  • Initial Cost: The initial cost of setting up a PoE lighting system can be higher than traditional lighting systems due to the need for specialized equipment and installation.
