Limelight by Lutron OEM Integration Guide
Integration Guide

1 Customer Assistance: 1.844.LUTRON1
This document is intended for luminaire/fixture manufacturers who are integrating Limelight by Lutron radio
sensor modules into their luminaires: either LL-EN-INTMOUNT (in-module internal antenna) or LL-EN-
INTMOUNT-A (supplied with an additional fixture-external antenna which enables bypassing Lutron’s RF
validation process) into their luminaires. Both can be installed with or without LL-PIR-L/M/H sensor assemblies.
This guide provides recommendations for electrical and mechanical integration of these parts into a luminaire
and their recommended manufacturing test procedures.
1. Standards
• RoHS Compliant
• FCC15.247 / IC RSS-247
• cULus Recognized for internal mounting at a fixture OEM
• IP65 and UL Wet Locations (LL-PIR-L/M/H) when lens assembly is installed correctly at
fixture manufacturer
• IP65 and UL Wet Locations (external antenna) when antenna is installed correctly at fixture manufacturer

RF Validation Process
This testing is for RF performance only of LL-EN-INTMOUNT integration (see Section 4. for LL-EN-INTMOUNT-A);
it is the OEM’s responsibility to ensure they follow all other Limelight product specifications
In order to ensure proper Limelight by Lutron system functionality, all lighting fixtures being considered for
LL-EN-INTMOUNT integration will need to be reviewed and validated by Lutron for RF performance. A picture of
the intended LL-EN-INTMOUNT integration or fixture design plan with the intended detailed install location and
orientation specified should be provided to Lutron via limelightOEMintegration@lutron.com. Lutron may request
additional fixture information along with fixture samples for further RF testing. If samples are requested, the
required performance testing may take up to 3 weeks, starting from the day the samples are received by Lutron.
For best RF performance of the LL-EN-INTMOUNT, the antenna should be kept 1.25 in (31.75 mm) from any
metal components (see Top View below) and the product should be elevated 0.25 in (6.35 mm) with standoffs
from a metal surface (see Side View below). The LL-EN-INTMOUNT should not be fully concealed in metal.
Lutron will request fixture samples for testing if either of these installation requirements are violated.
