Construction and finish
The LS-SQS-BK is a square swivel trim made from painted die cast metal, a material choice that keeps the faceplate rigid, cool and true to shape over years of service. The black finish is more than a style statement: a dark aperture absorbs stray light instead of bouncing it back at the eye, which is exactly why designers specify black trims in rooms with dark ceilings, media walls and display fixtures. The square faceplate measures 3 1/2" (89mm) wide, giving a clean geometric outline that lines up beautifully with square tile, cabinetry and coffered details — a welcome change from the standard round ring.
Light quality and aiming
Paired with a 7W MR16 LED bulb, this trim delivers 550 lumens through a 40° beam — narrow enough to create a defined pool of light, wide enough to cover a piece of artwork or a shelf without hot edges. The single CREE COB LED and a CRI greater than 90 mean colours stay honest: reds look red, whites stay neutral, and merchandise photographs well. The 90° swivel is the real hero. Once the trim is in the ceiling you can re-aim the adjustable pot light at any time — after the furniture moves, after the art gets rehung, after a store changes its display. And because the MR16 bulb is ordered separately in 2700K, 3000K or 5000K, you can change the whole feel of a room later without opening the ceiling.

Installation and compatibility
Installation is a recessed install with pressure fit clips into a Ø2 3/4" (70mm) cutout — squeeze the clips, push the trim up, and the spring tension holds it flat to the ceiling or cabinet panel. Each fixture includes an MR16 socket with a 15cm (6") wire lead, so wiring to your 12V supply is short and tidy. Remember that this is a 12V low-voltage product: it needs an appropriate 12V AC/DC supply, and the MR16 LED bulb is ordered separately under its own code (2700K, 3000K or 5000K, 7W, 40°, >90 CRI). The trim accepts MR16 / RD10 / RD7 LED modules, which keeps the parts list short on a big job — one trim reference covers several module configurations, so contractors stock fewer SKUs across a multi-unit project.
Applications and documentation
The spec sheet lists cabinet, display and downlighting as the core applications, and that is exactly where this trim earns its keep: glass display cases in a jewellery shop, millwork and pantry interiors in a custom kitchen, shelving in a wine room, artwork in a condo hallway, reception walls in a clinic or salon. It is equally at home in a restaurant banquette, a boutique change room or a home theatre where a black aperture disappears into a dark ceiling. Because it is dimmable, you can tune the level for daytime retail and evening ambience on the same circuit.
