What exactly is this part?The HS/VERS/9/MB/MB/CYL is a
decorative trim for the TUROLIGHT RGD-HS/VERS
LED surface discus line — not a complete fixture. The discus itself is the light engine and housing (PC housing, white finish); the trim is the visible face that you see from below. This version is finished matte black on the outer band and matte black on the inner face, and its cylindrical profile stands slightly proud of the ceiling for a modern drum silhouette. Ordering code 3660424, maximum outside diameter 8.94", maximum outside height 1.97". Because the trim is a finish accessory, one fixture SKU can be dressed several ways: brushed nickel, matte black, black and gold, white and gold, white and white, canopy style, or this black cylindrical style.
The fixture it's built forThis 9" trim is sized for the 9" host: RGD-HS/VERS/9/18W/MK5/WH/D, ordering code 3662202. That fixture delivers 1480 initial lumens from 18 W at 120 V, with a 120° beam angle for wide, even room fill and CRI ≥80 so skin tones, wood and paint colours stay true. The MK5 designation means
5CCT selectable — five colour temperatures chosen on the fixture: 27/30/35/40/50 K. Set warm for bedrooms and living spaces, neutral for kitchens and halls, cooler for laundry, garage-adjacent spaces or retail display. It's TRIAC dimmable down to 5%, so a standard forward-phase wall dimmer gives you real low-end control, and it's damp location rated for covered exterior ceilings and bathrooms.

Installation and compatibilityThe RGD-HS/VERS platform fits all types of J-box, which is what makes it such a favourite for renovations: no new housing, no attic access, no cutting a bigger hole. The trim attaches to the finished fixture, so if a client changes their mind about the look a year later, you swap the ring instead of the whole
ceiling light. Match the size exactly — a 9" trim belongs on a 9" discus; the 5", 7" and 12" fixtures each have their own trims. And since the trim doesn't touch the driver or the wiring, there's no impact on the dimming performance, the CCT selection or the cETL listing of the fixture.
Where it works and what's in the docsThink condo corridors, open basements, bedrooms with black ceiling fans, stair landings, mudrooms, covered entries and soffits, plus commercial spaces like salons, tasting rooms, clinics and small offices where a black
flush mount ceiling light disappears into a dark ceiling or pops against a light one. Designers often mix sizes — 9" over seating areas, 12" over a table — using the same black cylindrical trim throughout for continuity; for the larger scale see the
HS/VERS 12" matt black/matt black recessed trim or the warmer
HS/VERS 12" matt black/gold recessed trim. Full dimensional drawings, the complete decorative trim table and the ordering guide are in the HS/VERS/9/MB/MB/CYL spec sheet in the Documentation tab.
