What this part isThe HS/VERS/5/MB/MB/CYL is a
decorative trim, not a complete luminaire. It belongs to the TUROLIGHT RGD-HS/VERS
LED Surface Discus program, a family of round surface-mounted disc lights offered in 5", 7", 9" and 12". The base fixtures ship in a white PC housing, and the trim line exists so you can change the face of the light to suit the room instead of changing the light itself. This version pairs a matt black outer ring with a matt black inner ring in a
cylindrical profile, ordering code 3660415, maximum outside diameter 5.38" and maximum outside height 1.97".
Construction and lookWhere the standard HS/VERS trims sit almost flush at 0.75" of height and the recessed-style trims reach 1.39", this
cylindrical trim stands at 1.97", giving the fixture a visible black drum on the ceiling. That extra shoulder reads as intentional design: it frames the lens, softens the visual edge of the light, and matches black hardware, black faucets, black window frames and black cabinet pulls. The matt black on matt black combination keeps the ceiling calm — no shiny halo, no bright ring around the aperture — which is why it is a favourite for minimalist, industrial and modern farmhouse interiors.

Installation and compatibilityThe matching 5" discus is designed to
fit in all types of J-box, which keeps retrofits and new construction equally simple: no housing, no remodel can, just the junction box already in the ceiling. Wiring stays at
120 V, and the fixture is
TRIAC dimmable down to 5% with a compatible forward-phase wall dimmer, so you can take a bedroom or a dining nook right down to a soft glow. Select your colour temperature on the fixture before final mounting — the
5CCT selectable switch lets one product serve warm living spaces and cooler task areas. Then add the trim. Important: this is the 5" trim and it is meant for the 5" HS/VERS discus; the 7", 9" and 12" fixtures each take their own matching size.
Where it works and what else to look atCondo corridors, basement finishing, walk-in closets, laundry rooms, stairwells, covered entries and soffits (damp location rated), plus retail fitting rooms, café ceilings, dental and esthetics clinics — anywhere a row of black discs looks deliberate. Contractors like that one fixture family covers a whole job while the trims vary by room. To coordinate across a project, look at the
HS/VERS 12" matte white/matte white cylindrical trim for the same cylinder shape in white, the
HS/VERS 12" matt black/matt black recessed trim for a lower black profile, the
HS/VERS 12" brush nickel trim, or the
HS/VERS 12" matte white/gold canopy trim for a statement ceiling. The full technical PDF (HS/VERS/5/MB/MB/CYL Spec Sheet) is in the Documentation tab with the dimensional drawing and the complete ordering guide.
