LIGHTFAIR Stage Set for Rollout of Energy- Saving ILLUMRA Wireless Light Sensor

ILLUMRA, the leader in wireless battery-free controls, announced the release of a newsolar-powered light sensor that can run indefinitely on a few hours of light a day. The new product, when used with other wireless devices, creates a daylight harvesting solution that is both easy to install and use. This breakthrough technology may be seen at the upcoming LIGHTFAIR trade show in Las Vegas (EnOcean/ILLUMRA booth #2027).

“The new light sensor gives building owners a powerful tool to control costs,” said Jan Finlinson, director at ILLUMRA. “By reducing electrical light levels in a room and taking advantage of the ambient light, we could greatly reduce the world’s $200+ billion light bill*.”

The ILLUMRA light sensor communicates to controls through the uncrowded 315 MHz band, saving energy by lowering the output of artificial light when daylight is present in a room. Customers can reduce energy consumption 20 to 60 percent, depending on the devices used and the room configuration.

The wireless battery-free sensor communicates to a host of wireless products: relays, dimmers, room and task on/off controllers. It also integrates into systems using BACnet and wireless RS-232/Ethernet gateways.

Customers can use the new product in open-loop and closed-loop daylight-harvesting applications. When fully charged, the sensor can work in total darkness up to three days.

The ILLUMRA light sensor is small, measuring approximately 4x4x1 inches (10 x 10 x 2.5cm), and mounts on a ceiling or wall. Developed for indoor use, it has an internal antenna for best appearance, and an option to extend the antenna for best performance. The ILLUMRA light sensor is made of recyclable plastic, is RoHS compliant, qualifies for LEED credits and helps buildings comply with International Green Construction Code standard 189.1.

ILLUMRA is the largest North American supplier of self-powered, battery-free, wireless lighting control and energy management systems, and a member of the EnOcean Alliance. All ILLUMRA products operate using the EnOcean protocol: the standard for low-power wireless communication. Transmitters harvest the energy they require from the motion of a switch, light on a solar cell, or from temperature differentials. This allows them to operate indefinitely without the use of batteries. The ILLUMRA product line includes multiple products that operate in the uncrowded 315 MHz band, offering greater transmission range than other wireless technologies and minimal competitive traffic. Products are sold via dealers and OEM partners throughout the world. For more information about ILLUMRA and its products, please visit, or call (801) 349-1200.
