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

found 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.
