Application Examples
- Retail environments such as boutiques, showrooms and department stores where multiple beams highlight displays and merchandise.
- Hospitality spaces including hotel lobbies, guest corridors, lounges and restaurants requiring flexible accent and ambient lighting from a discreet aperture.
- Commercial interiors such as offices, conference rooms and reception areas where targeted illumination enhances architecture and branding.
- Gallery and museum installations where independently adjustable heads can be aimed at artwork or exhibits and fine-tuned with different beam spreads.
- Residential high-end applications including great rooms, home theaters and kitchens where a clean ceiling aesthetic and flexible aiming are desired.
Installation Tips
- Plan head locations carefully based on the objects or surfaces you want to illuminate, allowing enough space for each beam spread and aiming range.
- Use the adjustable bar hangers to span joists from approximately 13-7/8" to 25" and align the L-shaped hanger foot to the bottom of the joist for consistent ceiling height.
- For suspended T-bar ceilings, use the integrated T-bar notch on the bar hangers to secure the housing to the grid before ceiling tiles are installed.
- Observe IC rating limitations by allowing contact with insulation while avoiding direct contact with spray foam insulation as specified by the manufacturer.
- Follow conductor requirements and use supply conductors rated for 90°C minimum, ensuring all connections are made in the 40 cubic inch junction box.
- When using trimless installations, have a skilled drywall finisher float, sand and paint the mud plate so the opening is clean and flush before inserting trims.
- Install trims and optics after ceiling finishing, choosing the appropriate beam (spot, narrow flood or flood) and adjusting each head to the desired target.
- Verify dimmer compatibility with the selected Triac, ELV or 0-10V control system, and test operation at different levels to ensure smooth dimming performance.
