Why this fixture (constraint-first)
-
Open plenum rated (armoured cable & metal connectors) for plenum ceiling requirements.
-
Type IC + air-tight for insulated ceilings where air leakage control matters.
-
Deep regressed design for reduced glare compared to non-regressed trims.
Canadian Use Cases
- Condo/commercial ceilings where the plenum space is used and open-plenum-rated wiring is required.
- Basements where you need a shallow profile (3 1/2" depth) and limited clearance (3" required).
- Bathrooms or covered exterior soffits requiring a wet-rated recessed downlight (IP54).
- Commercial installs using 347V and 0–10V dimming (with the optional driver).
Check Before You Buy (prevents callbacks)
- Measure your ceiling cutout: must be 6 1/4" to 6 1/2".
- Confirm clearance: manufacturer states 3" ceiling clearance required.
- Pick your dimming/voltage: Triac 120V standard vs 0–10V 120–347V optional.
- If you need Dim-to-Warm (3000K–2000K) or 5CCT, this LD6R (18W) is the model where those options are listed.
- Plan your junction box fill: max 5×12 AWG or 8×14 AWG conductors.
Not For You If…
- Your ceiling cutout is outside 6 1/4" to 6 1/2".
- You cannot meet the 3" clearance requirement.
- You require a published dimmer compatibility list (not provided on the official product page).
