What is trimless lighting?

Frameless recessed LED for gypsum & drywall ceilings

Trimless lighting — also called plaster-in downlights, mud-in recessed lighting, or frameless recessed LED — is installed so the housing flange is skimmed flush with the ceiling. Only the light aperture remains visible, creating an uninterrupted architectural plane preferred by lighting designers.

Invisible architecture

Eliminate flanges and trim rings. Ideal for luxury residences, boutique hotels, and gallery-grade commercial interiors.

Plasterboard & gypsum ready

Perforated plaster frames bond with joint compound for crack-resistant gypsum ceiling lighting installations.

Project-ready optics

Fixed, adjustable, wall-wash, and deep-baffle options with high CRI and anti-glare performance for specification work.

FAQ

Trimless lighting questions buyers ask

Answers for importers, lighting brands, contractors, and project buyers sourcing plaster-in and frameless recessed LED from China.

Trimless lighting (also called plaster-in, mud-in, or frameless recessed lighting) is recessed LED lighting installed so the fixture flange is plastered flush with the gypsum or drywall ceiling. Only the light aperture remains visible — no bezel or trim ring — creating seamless architectural ceiling lighting.
Cut the specified aperture, fix the plaster frame level with the board, protect the opening with a plaster plug, then skim joint compound over the perforated flange. After sanding, priming, and painting, insert the LED module/reflector. Installation is typically first-fix for the frame and second-fix for the light engine — follow local electrical codes.
Decentlux is a China LED lighting manufacturer and supplier offering OEM/ODM trimless LED downlights, trimless linear lighting, and plaster-in architectural fixtures for wholesalers, lighting brands, and project contractors worldwide.
Hotels and hospitality, luxury retail, museums and galleries, offices and corridors, high-end residences, commercial interiors, and bathrooms when IP-rated plaster-in downlights are required. Any space where the ceiling is treated as an architectural surface benefits from trimless fixtures.
Sample orders typically start from 10–50 pieces for validation. Project and wholesale MOQ commonly begins around 200 pieces per SKU, with flexible runs for distributors and OEM partners. Tell Decentlux your quantity and we will confirm the nearest production window.
Yes. Customization includes CCT and CRI, beam angles, UGR anti-glare optics, DALI / 0–10V / TRIAC drivers, aperture size, round or square shapes, finishes (including custom RAL), private labeling, and packaging. ODM structural changes are available from drawings.
Traditional recessed downlights use a visible metal trim/flange to cover the cut-out. Trimless (plaster-in) fixtures hide the flange inside the ceiling finish, so the ceiling plane stays continuous. Trimless requires more coordination with drywall/plaster trades but delivers a higher architectural finish.
Fire-rated plaster-in options can be discussed for markets that require them (common in some residential UK/EU applications). Share your local fire and building code requirements so Decentlux can propose a compliant construction or partner assembly.
