Diagrams: Multiple diagrams illustrate the fixture's physical dimensions and mounting configurations. These include cross-sections showing the internal components, overall fixture dimensions, and how the mounting frame and trim attach. Specific diagrams show configurations for MVOLT UGZ, MVOLT DALI, MVOLT UGZ QDS, MVOLT UGZ EC1, and MVOLT UGZ ELR options, detailing their respective wiring and component placements. Another diagram shows the LBR4PFWCP configuration with detailed measurements.

Photometry

The following data presents photometric performance for specific configurations.

Diagrams: Photometric distribution curves are shown for two specific models (LBR4 SWW1 ALO2 AR LSS MWD MVOLT UGZ and LBR4WW SWW1 ALO2 AR LSS WW MVOLT UGZ). These plots illustrate the light intensity distribution in candelas per square meter (cd/sq.m) at various angles (0° to 90°). Zonal Lumen Summary tables break down the percentage of total lumens emitted within specific angular zones (e.g., 0°-30°, 0°-40°). Cone of Light data provides illuminance (FC) and beam diameter at different mounting heights. Average Luminance data is also presented.

Dimmer Compatibility

Not compatible with DALI or DMX dimmers. For specific compatible dimmers, see tables below.

Additional Data: JOT (Just One Touch)

The Sensor Switch JOT enabled solution offers a wireless, app-free approach to single room lighting control. JOT enabled products use Bluetooth® Low Energy (BLE) technology to enable wireless dimming and switching.

Diagram: Illustrates the JOT system setup: 1. Install JOT enabled fixtures and controls. 2. Pair by inserting the pairing tool into the wall switch pinhole and holding any button for 6 seconds. 3. Play: After pairing, fixtures dim to 10% brightness, and all products become fully functional.

Control System Integration

Example Diagram: Shows a 'Group Fixture Control' application diagram for fixtures with eldoLED drivers. It illustrates wiring for nPS 80 EZ Dimming/Control Packs, nPODM 2P DX Push-Button WallPod, nCM ADCX Daylight Sensor, and nCM PDT 9 Occupancy Sensor. The description explains how this setup enables manual control of fixtures in separate rows (A and B), incorporates daylight harvesting for Row B, and uses an occupancy sensor to turn off all lights when the space is vacant.

Wiring Key: CAT-5e Cable, Line Power, Low Voltage Dimming Wires.

Choose Wall Controls: nLight offers various wall controls with different features and user experiences, including Push-Button Wallpods and Graphic Wallpods.

UL924 Sequence of Operation

For nLight AIR devices with an EM option:

• EM devices remain at their high-end trim and ignore wireless lighting control commands unless a normal-power-sensed (NPS) broadcast is received at least every 8 seconds.
• Using the CLAIRITY+ mobile app, EM devices must be associated with a group including a normal power sensing device to receive NPS broadcasts.
• Only non-emergency rPP20, rLSXR, rSBOR, rSDGR, and nLight AIR luminaires with version 3.4 or later firmware can provide normal power sensing for EM devices.

nLight AIR System

nLight AIR is ideal for retrofit or new construction spaces where communication is cost-prohibitive. The integrated nLight AIR rPP20 Power Pack is part of each Lithonia LDN Luminaire, offering individually addressable controls for flexibility.

Simple Setup:

1. Install nLight® AIR fixtures with embedded smart sensor.
2. Install the wireless battery-powered wall switch.
3. Use the CLAIRITY app to pair fixtures with the wall switch and customize sensor settings.

Diagram: Shows the nLight AIR setup with a fixture, a wireless wall switch (rPODB 2P DX), and a mobile device for the CLAIRITY app.
