4,000 lm
Nominal direct output
A recessed drum luminaire that brings a broad disc of light into the ceiling. Choose from three nominal diameters, two direct shielding options and ceiling interfaces for T-grid or drywall installations.

| Direct shielding | RD: round dome lens / DL1: 1 in drop lens |
| Field-selectable output | FS option: 100% / 80% / 60% of selected maximum output |
| Color temperature | 2700 K / 3000 K / 3500 K / 4000 K; optional 4-CCT field selection |
| Color rendering | Ra 80 / Ra 90 |
| Mounting | F: T-grid flange / S: drywall spackle flange |
| Ceiling type | T1: 15/16 in tegular; T2: 9/16 in tegular; G1: 15/16 in lay-in; G2: 9/16 in lay-in; G3: 9/16 in slot-tee tegular; D: drywall |
| Circuits | 1 circuit |
| Control & dimming | 0–10 V, 1% dimming / DALI, 1% dimming |
| Input voltage | 120–277 VAC |
| Finish | White / black / custom RAL |
Choose a round dome lens or a 1 in drop lens to define the luminous face and edge. Review the matching photometric file for the selected configuration.


Choose the nominal diameter to suit the scale of the room, then coordinate output and spacing across the layout.

Select the ceiling interface and flange before finalizing the opening. Use the dimensional drawing to coordinate the fixture with the ceiling construction.
Choose the ceiling interface to match the grid and tile: 15/16 in or 9/16 in tegular or lay-in, or 9/16 in slot-tee tegular.
Use the drywall mounting configuration to integrate the circular light aperture with the finished ceiling.
Select 2700 K, 3000 K, 3500 K or 4000 K, or the 4-CCT field-selectable option. FS output selection provides 100%, 80% or 60% of the selected maximum.
Specify 0–10 V or DALI control with dimming down to 1%. The recessed configuration uses one circuit.
Choose white, black or a custom RAL finish. Coordinate the diameter, housing finish and mounting details with the interior palette.
Integrate circular light into T-grid or drywall ceilings, with the fixture body concealed above the finished surface.
