Airwave...Wireless. Batteryless. Limitless.
Sensors energized by the light they collect. Switches powered by the motion used to operate them. Airwave is an affordable, dynamic and eco-sensitive solution that delivers maximum design flexibility and energy savings to meet the needs of virtually any environment—and the people within them.
Powered by organic energy
The latest addition to a growing family of innovative Ledalite technologies, Airwave wireless controls represent a giant leap forward in flexibility, sustainability and profitability. Add Airwave to your next project and break free from a wired world.
By using organic sources of solar and kinetic energy which naturally occur in the space, Airwave provides wireless individual personal control, daylight harvesting, occupancy sensing, and full range dimming for private offices, open plan areas, conference rooms, and other spaces where the ability to control energy and lighting are essential.
Sustainability made simple
In today’s climate of conservation, a global focus on preserving energy inspires building designers to embrace new technologies that contribute to LEED® certification. Airwave is truly a sustainable innovation; it decreases initial construction costs, minimizes operational expenses, and lessens environmental impact by reducing battery use and copper wiring infrastructure.
Real 3-way dimming is a reality
Traditional 3-way control schemes limit dimming to occur from just one hardwired location. With no hardwiring and no batteries to worry about, Airwave self-powered kinetic energy devices deliver full range dimming and ON/OFF control from anywhere in a space. In large open areas or multi-purpose spaces, combinations of battery-free wall switches and handheld remotes can be used to create a limitless myriad of customized lighting scenes making spaces more functional and flexible.
Compatible with wired + wireless occupancy sensors
Dim to OFF
All occupancy sensor vacancy signals sent to the Airwave transceiver initiate dimming of luminaires, eventually shutting OFF when the space is unoccupied. This smooth, gradual transition means environments remain dynamic, efficient and ergonomically sensitive to the people who inhabit them.
24V Wired Occupancy Sensors
Airwave is compatible with wired occupancy sensors, including infra-red (PIR), ultrasonic, dual-technology and microphonic devices. The transceiver provides 24V (50mA) power for these devices, reducing the need for power-packs and low voltage wiring. Using wired occupancy sensors with Airwave is key to enhanced energy savings, and allows designers utilize the most reliable sensor technology without coverage concerns or batteries.
315 MHz Wireless Occupancy Sensors
Airwave is fully compatible with Philips Ledalite or other 315 MHz EnOcean enabled wireless occupancy sensors. Most available wireless occupancy sensors rely on battery power to remain operational and utilize only infra-red (PIR) detection technology which may be suitable for some applications. Wireless occupancy sensors can be useful energy savings tools when applied correctly, however using an Airwave kinetic wireless switch in conjunction is a recommended best practice for fail-safe reliability.
Enhanced energy reduction with Response® Daylight Sensors
In spaces with ample amounts of daylight, discreet Response Daylight sensors maximize savings by automatically dimming when there is enough illumination detected in the space.
Response sensors are FREE and optionally integrated in all Ledalite suspended luminaires. Response photosensors set the maximum output based on the ambient lighting condition. Although users have the ability to dim lights, energy savings are ensured by the fact that light levels cannot be increased beyond photosensor set points.
A global focus on sustainability has inspired designers, architects and builders to embrace new technologies and create environmentally sensitive structures. By delivering a unique combination of energy performance, control and flexibility, Airwave greatly expands the possibilities for sustainable building design. Airwave + other Ledalite technologies and sustainable lighting practices help contribute LEED points.

Reconfigure. Rezone. Rethink.
Controlling light systems in an open office can be a challenge. Large areas of coverage often conflict with the specific lighting needs of employees’ semi-private areas. The hub of system intelligence, the Airwave transceiver, can easily transform large areas of uncontrolled lighting into smaller, discreet zones with improved user accessibility and control. A strategic design principle is to use one Airwave transceiver and multiple switches and photosensors to control all luminaires within each lighting zone. This optimizes the lighting system for energy and cost savings and also enables occupants to actively dim lighting to more preferred levels, thereby enhancing their own productivity and comfort throughout the workday.
The future demands response
The demand for electricity varies with the time of day and season. Peak demand periods often require utilities to operate temporary energy sources that are both inefficient and costly. Demand Response load shedding programs help reduce electrical loads during peak periods and can result in significant savings of both energy and dollars. Every Airwave transceiver is embedded with four levels of Demand Response intelligence. Airwave wirelessly reacts by slowly dimming and/or turning off lighting loads to dramatically and immediately reduce the lighting energy.
How It Works
Wireless Kinetically Powered Energy Devices
The Airwave switch is a self-powered and battery-free device that transmits wireless signals to transceivers to dim luminaires and turn them on or off. Each press and release of the switch generates enough kinetic energy to wirelessly transmit a command to a transceiver. A unique sequence of clicks can be used to link Airwave switches to transceivers—wirelessly. Airwave switches produce far fewer high-frequency fields than conventional wired light switches, making it a very safe technology. Each switch has its own unique identification address, ensuring that the settings of the Airwave switch linked to the transceiver do not unintentionally change by proximity to other wireless devices. Multiple Airwave switches and photosensors can be installed next to other wireless devices.
Wireless Solar Powered Photosensor
The Airwave photosensor is a battery-free wireless device that harvests solar energy to operate via integral miniature photovoltaic cells. The photosensor monitors light levels in a space and wirelessly transmits signals to the transceiver. The transceiver then uses the data to automatically dim, brighten, or turn lights on or off based on the ambient light level. The optimal placement for an Airwave photosensor is 6-10' from a window or representative work areas.
Occupancy Sensing Compatibility
The Airwave transceiver also receives signals from, and provides power for, 24V occupancy sensors thereby eliminating the need for additional power packs and low voltage wiring. Occupancy sensors significantly enhance energy savings by automatically dimming down and then turning lights off when the space is vacant. Airwave is fully compatible with Philips Ledalite or other 315 MHz EnOcean enabled wireless occupancy sensors. Most available wireless occupancy sensors rely on battery power to remain operational and utilize only infra-red (PIR) detection technology which may be suitable for some applications.
The Airwave transceiver is an intelligent device that receives wireless signals and sends commands for on/off functions and 0-10V dimming to individual light fixtures or a group of luminaires in a lighting zone. Fixtures within each zone can be grouped using Airwave flex connectors.
The transceiver can also:
- Responds to wireless signals from Airwave switches and photosensors, as well as other wired and wireless occupancy sensors.
- Operates as a low voltage power pack for 24V occupancy sensors.
- Receives a signal from a 24V wired occupancy sensor and wirelessly transmits on/off occupancy commands to other distant Airwave transceivers.
- Repeat wireless transmission signals from Airwave switches and photosensors to other distant Airwave transceivers.
- Reacts to 4 levels of Demand Response (DR) event load shedding signals and wirelessly transmits DR signals to other distant Airwave transceivers.
Airwave Best Practices
Needs-based lighting zones
The intelligent Airwave transceiver can easily transform large areas of uncontrolled lighting into smaller, discreet zones with improved user accessibility and control. A strategic design principle is to use one Airwave transceiver and multiple switches and photosensors to control all luminaires within each lighting zone. This optimizes the lighting system for energy and cost savings.
Wireless switches and photosensors require no hardwire connections, allowing for easy placement and repositioning anywhere in a space. Transceivers can receive wireless signals from 30 devices located up to 100 feet away, and through up to five walls. Just a single Airwave transceiver can receive signals from multiple switches and occupancy sensors to deliver maximum functionality and outstanding flexibility.
The optimal placement for an Airwave photosensor is 6-10' from a window over representative work areas. Placement of photosensors must be within the light field of the fixtures it is linked to and should not be placed in direct sunlight. It is important not to use photosensors with suspended light fixtures where lamp light is shining directly into the photosensor.
How the Technology Works
If there are no batteries and no wires, how does this technology work?
The devices get their power from energy sources which naturally occur in the space. For example, just the simple motion of pushing the Airwave Switch creates enough kinetic energy to send wireless signals to luminaires allowing on/off control and full range dimming. Similarly, the solarpowered Airwave Photosensor gets its operating energy from internal photovoltaic cells which are charged by exposure to light.
What wireless technology does Airwave use?
The core technology is based on miniaturized energy harvesting modules with ultra-low-power radio transmission (315 MHz). The developer of this award-winning and patented battery-free wireless technology is EnOcean, a spin-off of Siemens Corporation.

How do I install the Airwave Transceiver?
The Airwave Transceiver is wired directly to a junction box that controls a lighting „zone? that may contain a single fixture or a group of fixtures.
The Transceiver is then an intelligence center that controls the lighting zone based on the information or commands that it receives from connected devices, such as an Airwave Switch, Handheld Remote or Photosensor.
How do you link an Airwave Switch to an Airwave Transceiver?
There are 2 primary methods of linking a Switch to a Transceiver: (1) manually and (2) remotely. Remote linking is available so that reconfiguration and addition of devices can occur easily after the initial commissioning has occurred.
What is the maximum electrical load that can be controlled by an Airwave Transceiver?
Airwave Transceivers are certified to control up to a 20A circuit at 120/277V and 15A at 347V.
Switching & Dimming
Can one Airwave Switch control multiple Airwave Transceivers?
Yes, any one Switch can control as many Transceivers that are within range and linked to that Switch.
Can Airwave Switches be used with standard metal electrical switch box?
Yes. The Airwave Switch recesses into the Switch box allowing a standard wall plate to remain flush with wall surface.
How often do Airwave Switches and sensors require maintenance?
There is never a need to service these devices or replace batteries. The Airwave switches are self-powered with kinetic energy and the photosensors solar powered.
Can Airwave Switches be surface mounted?
Yes. Airwave Switches can be surface mounted using the optional back plate. Airwave back plates are available in 1, 2 and 3-gang configurations.
Can I use a metal face plate with an Airwave Switch?
It is not recommended to use a metal face plate with an Airwave Switch as it will decrease the transmission range.
How will my Airwave devices and settings be affected during a power outage?
When power is restored after an outage or failure, lights will come on at the same level they were prior to the outage.
Can a wireless Airwave Switch be used with a conventional wired Switch?
Yes. However, the Switches will not function as 3-way Switching; the conventional Switch will function as an in-series interrupt to the wireless Transceiver.
Compatibility & Interoperability
Does Airwave work with occupancy sensors?
Yes. Airwave is compatible with 24V wired occupancy sensors and other EnOcean-enabled 315MHz wireless occupancy sensors.
Does Airwave work with Ledalite’s fixture integrated Response Daylight Sensor?
Yes, Airwave is compatible with Response Daylight Sensors. Using this combination of technologies, the fixture integrated Response Daylight sensor determines the maximum available luminaire output based on the detected light levels in the space. Just like using Response with a typical wired Switch/dimmer, the Airwave Switch/dimmer can further reduce luminaire output or turn it off, but cannot override the fixture integrated Response Daylight sensor.
What is the range of the Airwave wireless transmission?
On average, transmission range indoors is approximately 100 feet (30 meters). The range of the transmission depends on the environment around the Transciever. Range planning is very important when applying this technology. Placing Transceivers behind metal (i.e., ductwork) can limit or block signals from being received.
What happens if the transmission distance is greater than 100 feet?
One option is to move the Switch closer to the Transceiver. The other option is to set a Transceiver that is within range into a “Repeater” mode to propagate the wireless signal. Setting a Transceiver to “Repeater” mode does not reduce any of its original functionality.
Can Airwave transmit through walls?
Yes. Airwave can transmit through brick, concrete, wood, glass, steel studs, acoustic tile ceilings, plaster, and drywall.
What spacing should be maintained between Airwave devices and other wireless transmitters?
Airwave Switches and Photosensors can be installed next to other wireless transmitters. However, it is suggested that Airwave Transceivers be positioned at least 20 inches (50 cm) away from other transmitters such as wireless routers, computers, audio and video equipment.
What do I do if there is a metal door or metal wall obstructing the wireless transmission?
One option is to move the Switch away from the metal obstruction and/or closer to the Transceiver. The other option is to set a Transceiver that is within range into a “Repeater” mode to propagate the wireless signal further and/or around the metal obstruction.
How does the Airwave Photosensor work?
The Airwave solar powered, wireless and battery-free Photosensor detects ambient daylight levels and then transmits wireless signals to the Transceiver which then automatically and gradually adjusts luminaire output to save energy.
What is the minimum light level required for the Airwave Photosensor to remain charged?
The Photosensor will charge at very low light levels. The design is such that, when there is enough light to warrant daylight harvesting, there is enough solar energy to power the Airwave Photosenor.
Does the Airwave Photosensor need to be fully charged before it will work?
No. The Photosensor will begin transmitting information when it begins charging, which is only minutes after being exposed to light. It takes approximately 6 hours for the Photosensor to become fully charged.
How often does the Airwave Photosensor transmit the light level to the Airwave Transceiver?
The Photosensor monitors light levels every 10 seconds and transmits if there has been a change. If there has not been a change, the Photosensor will automatically transmit the light level approximately every 100 seconds.
What is the measurable light range of the Airwave Photosensor?
The measurable light range is 0-50 footcandles (0-510 lux)
Safety, Security, & Regulatory Compliance
Is Airwave safe?
Yes. Airwave Switches produce 100 times less intensive high-frequency fields than traditional light Switches, making Airwave a very safe technology. Airwave Switches and Photosensors allow for use in a wide array of applications including transmission-sensitive areas.
How secure is Airwave?
Each Airwave Photosensor, Switch, and Transceiver has its own unique 32-bit identification address ensuring that settings cannot be manipulated or unintentionally changed by other wireless devices.
Does Airwave wireless technology interfere with other wireless frequencies?
No. Airwave operates at 315Mhz which is a unique radio frequency that does not interfere with other common wireless devices such as mobile phones, Wi-Fi networks, and AM/FM radio.
Does Airwave meet regulatory standards?
Yes. Airwave is FCC and UL approved for use in the United States, and IC and CSA approved for use in Canada
