What this part isThe HS/VERS/9/MB/MB is a decorative trim for the TUROLIGHT RGD-HS/VERS
LED Surface Discus platform. The discus family is a slim round surface fixture that mounts flat to the ceiling and fits all types of J-box, and TUROLIGHT publishes a full range of decorative trims so the same light can wear different looks. This one is the
recessed-style matte black trim in the 9" size, finished matte black on the outer ring and matte black inside the recess. Ordering code 3660422, model number HS/VERS/9/MB/MB — copy that exactly when you specify, because the same family also offers brushed nickel, white, gold and cylindrical versions in each diameter.

The fixture it dressesMatched to the 9" discus, model RGD-HS/VERS/9/18W/MK5/WH/D (ordering code 3662202), the trim rides on a fixture rated
18W at 120V delivering 1480 initial lumens with a 120° beam angle and
CRI ≥80 for honest skin tones, wood grain and paint colours. That model is an MK5 unit, meaning 5 selectable colour temperatures chosen right on the fixture, so one part number covers warm living spaces and cooler task areas. It is
TRIAC dimmable down to 5%, damp location rated, cETL listed, built with a PC housing, rated L70 at 50,000 hours, covered by a 5-year limited warranty and specified for an operating temperature range of -10˚C ~ +45˚C. Every one of those ratings belongs to the fixture — the trim is the finishing layer that sets the visual style.
Installation and compatibilityBecause the discus itself mounts to the junction box and the trim attaches to the fixture face, swapping finishes later is a quick job and does not touch the wiring. Match the diameter exactly: a 9" trim goes on a 9" discus, a 12" trim on a 12" discus. If your ceiling plan calls for other sizes or a different look, stay inside the same family with the
HS/VERS 12" matt black/matt black recessed trim, the
HS/VERS 12" matte white/matte white recessed trim, the
HS/VERS 12" matte white/matte white cylindrical trim or the
HS/VERS 12" brush nickel trim. Ordering by the code shown on the spec sheet is the safest way to avoid a mismatch on site.
Where it works and what's documentedThink hallways and stairwells where a black ring breaks up a white ceiling, bedrooms and open-concept kitchens in a modern farmhouse or industrial reno, condo entryways, basement rec rooms, and small business spaces — boutiques, salons, cafés, clinic corridors — where dark hardware matches the branding. Damp location rating on the discus also opens the door to covered soffits and well-ventilated bathrooms. Contractors often buy trims in a single finish across a floor to keep the ceiling reading as one design, then vary only the diameter room by room. The full
spec sheet PDF for HS/VERS/9/MB/MB, including the dimensional drawing, the decorative trim tables and the ordering guide, is in the Documentation tab — download it before you order so the size, the code and the finish all line up.
