What this trim actually isThe HS/VERS/12/MB is a
decorative trim ring for the TUROLIGHT
LED Surface Discus family (RGD-HS/VERS). The Surface Discus is a round, ultra-slim ceiling luminaire that mounts flat to any standard J-box; the trim is the visible finishing ring that surrounds it. Ordering code 3660408, model number HS/VERS/12/MB, maximum outside diameter 11.87", maximum outside height 0.75". The matt black finish is uniform and low-gloss, which means it reads as a clean dark circle on the ceiling rather than a shiny ring that catches every lamp in the room — exactly what designers want when the rest of the hardware is black.
The fixture it dressesThis trim is sized for the 12" model of the family, RGD-HS/VERS/12/24W/MK5/WH/D (ordering code 3662203). That host luminaire draws
24W at 120V and delivers 2000 initial lumens with a 120° beam angle, CRI ≥80, and an L70 rating at 50,000 hours. It is
TRIAC dimmable down to 5%, damp location rated, cETL listed, and built with a PC housing. Its MK5 code means
5 selectable colour temperatures, chosen on the fixture itself. The trim doesn't alter any of that — it simply changes what you see. If you're specifying a full assembly, order the luminaire and the trim finish you want together.

Installation and compatibilityInstallation is about as simple as lighting gets: the Surface Discus fits all types of J-box, and the trim installs with the fixture at the ceiling, so a finish change doesn't require opening the ceiling or pulling new wire. Since the host luminaire runs on
120V line voltage and dims with standard
TRIAC (forward phase) dimmers, an existing dimmer circuit usually carries over untouched. Keep the operating temperature range of the luminaire in mind (-10˚C to +45˚C) — useful for covered porches, garages and Canadian three-season rooms where the fixture's damp location rating matters. Note that this trim matches the
12" size only; for a 5" fixture you'd use the 5" trim instead, such as the
HS/VERS 5" brush nickel trim.
Where it works and what else to look atThink modern kitchens and islands, hallways, bedrooms, staircases, finished basements, laundry and mudrooms, walk-in closets and bathrooms, plus light commercial spaces: salons, boutiques, dental and medical waiting rooms, small offices, coffee shops and short-term rentals. A 12" disc with a matt black ring gives a big, generous circle of light over a dining table or at the top of a stairwell, while the black outline hides ceiling smudges better than white. Want a different vibe? There's the two-tone
HS/VERS 12" matt black recessed trim for a deeper recessed look, the warm contrast of the
HS/VERS 12" matte white/gold recessed trim, or the sculpted
HS/VERS 12" matte white/gold canopy trim. The full
technical spec sheet for the HS/VERS/12/MB, including the dimensional drawing and the complete decorative trim ordering table, is in the Documentation tab — worth a look before you order a batch for a whole floor.
