Step-by-Step Installation:
- Prepare the Ceiling: Turn off power at the circuit breaker. Use the provided template to mark and cut a 4.18-inch (10.6 cm) diameter hole in the ceiling drywall. Ensure there are no obstructions (joists, pipes, wires) in the ceiling space.
- Connect Wiring: Open the remote driver junction box. Connect the building's electrical supply wires (hot, neutral, ground) to the corresponding wires in the junction box using appropriate connectors (e.g., Wago connectors, if supplied). Secure the wires according to local electrical codes.
- Insert Junction Box: Place the wired junction box through the ceiling cutout. The box is designed to sit above the ceiling.
- Connect Fixture to Junction Box: Connect the cable from the downlight fixture to the remote driver junction box. Ensure a secure connection.
- Install Downlight Fixture: Fold the spring clips on the downlight fixture upwards. Insert the fixture into the ceiling cutout. The spring clips will automatically snap down and secure the fixture against the ceiling surface.

Operating Instructions
The HALO RL downlight offers adjustable settings for light output and color temperature to suit various preferences and environments.
1. Selectable Color Temperatures (seleCCTable™)
Before final installation or by carefully pulling down the fixture, locate the color temperature switch on the driver junction box. Choose from five distinct color temperatures:
- 2700K: Warm White
- 3000K: Soft White
- 3500K: Neutral White
- 4000K: Cool White
- 5000K: Daylight

2. Selectable Lumen Output
Adjust the brightness level by selecting the desired lumen output on the switch located on the lighting module or driver junction box. This model offers two lumen options:
- 600 Lumens
- 900 Lumens

3. Dim-to-Warm Feature
When the Dim-to-Warm setting is selected via the color temperature switch, the light will transition from a bright white (3000K) to a warm, candlelight glow (1800K) as it is dimmed using a compatible dimmer switch (sold separately). This feature creates a cozy and inviting atmosphere.
