Energy efficient lighting a priority- The “PoE” benefit

Energy-efficient lighting moving to top of customer priority list.

Updated publication Jan 2024

New research could provide insight into utility lighting programs. Research across 2,000 customers of three utilities revealed that annual energy savings from lighting is becoming increasingly important, ranking third for most applications. Now in 2024 energy efficiency is top of mind.

Federal and State agencies are required to place energy efficiency measures.

Utilities that understand their customers’ preferences can provide the innovation that customers want and need to save energy. The results show that consumers will continue to benefit from lower utility costs via utility programs designed to reduce residential lighting energy use through innovative lighting efficiency programs.

POE Lighting Power Over Ethernet

PoE technology for LED lighting -benefits beyond efficiency, and as LED-based lighting is now a mainstream technology. Replacing incandescent, halogen, and compact fluorescent lights (CFLs) in commercial, industrial, and residential use is a preferred practice.

What is PoE Lighting?

What is Power Over Ethernet?
Power over Ethernet (PoE) is a technology that allows network cables to carry electrical power. It’s used to provide both power and data connection to devices like IP cameras, VoIP phones, wireless access points, and other networked devices. One cable for all. This eliminates the need for separate power supplies or electrical wiring, simplifying installation and reducing clutter.
It is delivered via low voltage, typical 24, VDC, which makes is safe to deploy.

Benefits in network management- let there be varied light.

Being able to communicate via network allows for a variety of controls like changing light intensity or even assisting Video recording in a variety of light situations, or no light at all.

New lighting technology based on LEDs and new “smart driver” embedded controls allows for better flexibility of dimming and motion sensors. Benefits of LEDs are well documented and include a longer operational life, higher energy efficiency, and tiny size.  Given their longer life, LEDs lower the access/safety risks and high labor costs of replacing a hard-to-reach lamp. LEDs also costs less to operate. The brightness of the light emitted by a 10W LED lamp is roughly equivalent to a 60W incandescent bulb.  With the ability to take lighting to network via web smarts, any type of programmed response is possible. Color and temperature variation is easy to manage as well as better ability to collect data and make additional adjustments over time. Because IOT and web-based technology is low voltage DC, it meshes well with LED drivers that are also DC.

The application of PoE in the context of Alternate E Source Smart Sensors indicates that these lights like our building sensors, can be powered and connected to a network using a single Ethernet cable. Lighting can be controlled via network such as being triggered through physical threshold alerting -providing a light on the situation for not only security for clear visibility to the user.

Safer Building -Smarter technologies 

Power over Ethernet (PoE) lighting is a low voltage technology that allows electrical power and data to transmit concurrently on a single twisted-pair cable. PoE lighting has several safety advantages in sensitive areas, such as:

1. Pathways to safety:

PoE lighting can be programmed to create pathways to safety in the event of a physical threat such as a fire, intruder, or natural disaster. If employees or cleaning personnel are in the space later in the evening, the lighting system can operate automatically to ensure safety.

PoE lighting fixtures offer a great solution for emergency lighting, it provides a low electrical profile that emergency support power systems can easily run.

2. Risk Mitigation: PoE increases safety and eliminates the need for a crew of electricians for installation and the inevitable modification. As LED lights need low voltage DC power to operate, AC powered LED fixtures must convert their power source through a transformer to DC. We can support converted lighting fixtures, however there is some heat loss to consider. By utilizing lighting apparatus that is designed for PoE we can save more energy by avoiding power conversion. The direct low voltage connection is a safer technology. In areas of mechanical equipment rooms -this lighting produces less heat, no spark, and is better suited for sensitive or hazardous locations.

3. Energy Savings: because PoE (Power over Ethernet) is a technology that allows power and data to be transmitted over a single low-voltage Ethernet, PoE can contribute to energy efficiency in lighting in several ways:

PoE reduces the power consumption of LED lighting by enabling more precise and flexible control over the lighting system. For example, PoE can allow users to turn on or off individual lights, adjust the brightness and color temperature, and schedule lighting patterns according to occupancy or time of day.

PoE can also reduce the energy losses associated with AC-DC power conversion, which is typically done by multiple LED drivers in traditional lighting systems. By consolidating the power conversion at one or more PoE switches, PoE can improve the overall efficiency of the lighting system. So smart embedded drivers can be controlled in a variety of ways.

PoE can also enable the integration of lighting with other building systems, such as HVAC, sensors, security, and analytics. This can provide valuable data and feedback on the energy usage and performance of the lighting system, as well as the opportunity to optimize the operations and reduce the overall consumption of the building.

By utilizing PoE technology wins when you add the advanced benefits of networking the lights using the Ethernet local area network (LAN). This allows for wireless remote logic as well as new network platforms to offer control via cloud. Because of the low voltage DC options, the ability to create new levels of lighting, and lighting display are now possible.

Cost Savings utilizing PoE lighting.

PoE lighting is a promising solution for improving the energy efficiency and sustainability of buildings, as well as providing more comfort and convenience for the occupants. Efficiencies and Incentives are now available to commercial buildings.

Alternate E Source provides new lighting technology capable of to be managed in a variety of networked ways. We believe in creating the most appropriate turnkey solution architecture, and we welcome inquires.
