Limelight by Lutron Wireless Fixture Controls

The Limelight by Lutron radio sensor modules are radio-frequency (RF) control devices integrated into fixtures by OEMs. They control 0-10V electronic LED drivers in exterior (outdoor) fixtures such as those in parking garages and parking lots. They are often connected to a PIR sensor assembly to receive motion and daylight sensor signals. A Limelight Gateway is required to enable wireless fixture controls and sensor functions. A Limelight Gateway connects fixture controls and sensors into a high performance wireless system.

Features

Fixtures can be grouped together to turn an entire floor on at once to make sure parking areas have plenty of light available.
Limelight by Lutron uses sensors to intelligently reduce power consumption and will email monthly reports of energy usage.
Radio Sensor Module is available with an internal antenna (inside the enclosure) (LL-EN-INTMOUNT), or with an output terminal for an external antenna (supplied) (LL-EN-INTMOUNT-A). An external antenna version does not require fixture RF validation.
Limelight by Lutron does not require wireless repeaters and typical jobs are completed with a single gateway. A cellular gateway option eliminates the need to get an Ethernet connection.
Single sign-on for Lutron interior and exterior controls when connected to Enterprise Vue.
Either an LL-EN-INTMOUNT or an LL-EN-INTMOUNT-A control device is integrated into the fixture with an (optional) LL-PIR sensor assembly.
Fully metallic fixtures generally integrate LL-EN-INTMOUNT- A. Fixtures with considerable plastic may use LL-EN-INTMOUNT.

System Components

Limelight by Lutron Enabled Luminaire

The Limelight by Lutron wireless radio sensor module (RSM) is integrated into a variety of luminaires. Fixtures with an integrated RSM can turn on/off and provide dimming capability using 0–10 V. A Limelight by Lutron enabled fixture requires no special communication wiring or special installation instructions. Installation is equivalent to a simple (non-Limelight) luminaire. When AC (120–277 V~) power is applied, the fixture powers up with a factory default setting of 100% light output until the Limelight by Lutron commissioning process begins.

Contact Lutron for assistance in identifying current OEM fixture offerings for your application at 1.844.LUTRON1.

Limelight by Lutron System Compatibility

Lutron’s RSMs are compatible with the entire Limelight by Lutron product line and can be designed into Limelight systems with various modules. The same High Density Mesh technology is shared across Limelight by Lutron products allowing a network to be created between all Limelight modules. A Gateway serves as the communication hub between the RSMs, other modules, and the Web User Interface. A Gateway can support up to 800 modules. Additional system details and other model numbers can be ound here:

Limelight by Lutron Radio Sensor Module (RSM)

Every RSM has a fully integrated wireless radio.
The radios use HDM (High Density Mesh) wireless technology to ensure extremely reliable, long-range performance in outdoor environments. These radios provide:

A robust, redundant communications scheme.
Communication among multiple floors above or below in parking facilities.

Each radio communicates to the “neighbor” radios around it, creating a high- density mesh.

This redundant communications system enables Limelight by Lutron to be self- healing. If a radio ever stops functioning or is vandalized, the other radios will immediately search out and establish communication with other neighbors in the mesh. This high-density mesh system enables the Limelight by Lutron control system to operate smoothly even in the most difficult conditions

Motion Sensor: LL-PIR, a passive infrared motion sensor, is an optional addition to OEM fixtures with LL-EN-INTMOUNT and LL-EN-INTMOUNT-A
- Maximizes motion sensor coverage.
- Captures all sensing activity (time of day and fixture number) in a centralized database for activity reporting and analysis.
Daylight Sensor: Daylight harvesting capabilities are supported.
- Measures daylight every 15 minutes (programmable).
- Measures foot candles per fixture to analyze for maximum harvesting capability.

Coverage

All units on the graph are shown in ft (m)

Limelight by Lutron PIR

Limelight by Lutron PIR can be configured wirelessly to have different sensitivity levels depending on its environment.

Sensor sensitivity can be adjusted (in the software) to reduce coverage.
Significantly hot or cold temperatures can substantially reduce the sensitivity of motion sensors.
Mounting height greater than 15 ft (4.6 m) reduces the likelihood of a motion sensor detecting a pedestrian. Sensors for pole mounted area fixtures are intended to detect vehicular motion.
Insufficient spacing between fixtures can create gaps in motion sensor coverage where motion will not be detected.

Height: 8 ft (2.4 m), LL-PIR-L
Height: 20 ft (6.1 m), LL-PIR-M
Height: 40 ft (12.2 m), LL-PIR-H
