Built to be aimed
The LS-RDS-BK belongs to the LumenstarLED swivel trim family, offered in square or round shapes and three finishes — brushed nickel, black and white. This SKU is the round swivel trim in black, a painted die cast metal trim whose weight and rigidity you feel the moment you pick it up. The 90° swivel lets the head tilt and turn inside the ring, so a row of downlights can wash an accent wall, graze a stone fireplace or spotlight a display without ever moving the housing. That is the whole advantage of an adjustable recessed trim over a fixed one: you set the aim after the ceiling is closed, on site, with the furniture in place.
Light quality with the right bulb
This trim is built around the MR16 LED bulb, sold separately. With the matching 7W 12V AC/DC MR16 LED bulb, you get 550 lumens from a single CREE COB LED, a tight 40° beam and a CRI greater than 90 — the kind of colour rendering that makes wood grain, food, fabric and skin tones look right instead of flat. Three colour temperatures are available so you can match the mood of the room: 2700K warm white (LS-MR16-7W-27K), 3000K warm white (LS-MR16-7W-3K) and 5000K white (LS-MR16-7W-5K). The system is dimmable, which matters in dining rooms, hotel lobbies and restaurants where the same fixtures serve lunch service and late evening.

Installation and compatibility
Installation is straightforward recessed work: cut a Ø2 3/4" (70 mm) hole, run your 12V supply, connect the included MR16 socket with its 15 cm (6") lead, then push the trim up until the pressure fit clips grab the ceiling. The 1/8" (3 mm) flange keeps the reveal minimal so the black ring reads as a deliberate dot on the ceiling. Order codes are separate for trims and bulbs, so count one trim plus one MR16 LED bulb per opening. If you want a different look on the same project, the family also includes LS-SQS-BK (black square), LS-SQS-BN and LS-RDS-BN (brushed nickel) and LS-SQS-WT and LS-RDS-WT (white) — handy when the kitchen gets black trims and the hallway stays white.
Where it earns its keep — and the paperwork
The manufacturer lists cabinet, display and downlighting as the core applications, and that is exactly where these black round pot light trims shine: under and above millwork, over a bar or island, inside a retail display case, along a gallery wall in a condo corridor, or in a clinic waiting room where a soft 2700K accent softens the space. For Canadian renovation work, the compact 70 mm cutout is friendly to tight joist spacing and drop ceilings where a full-size recessed downlight would not fit. The complete LS-RDS-BK spec sheet — features, dimensions, ordering codes and bulb options — is available as a PDF in the Documentation tab; print it for your cutout template and keep it with the project file.
