Astro Trimless Recessed Downlight

The Astro Trimless Recessed Downlight is a plaster-in, trimless recessed downlight from Astro's Trimless range. It’s designed to disappear into the ceiling while delivering focused, downward illumination for bathrooms and other architectural spaces where a discreet, high-performance light is required.

The fixture uses a square mounting plate that’s plastered into the ceiling for a seamless, trimless look, while a round aperture and deep conical baffle create a minimalist geometric contrast. The visible surface is finished in a matte, textured white intended to blend with standard plaster ceilings.

Despite its slimline profile, the luminaire features a robust internal housing and a recessed design that minimises visible depth and keeps the lamp out of direct view. The combination of a square outer frame with a circular inner aperture keeps the aesthetic clean and contemporary.

Light is delivered as a fixed, downward beam — the deep baffle controls glare for comfortable general or task illumination. The housing accommodates a single GU10 LED lamp or a compatible LED module (accepts GU10, max 6W), allowing you to select beam angle and colour temperature to suit the space.

This product is IP65 rated and fire-rated, making it appropriate for wet zones and specialised architectural installations. For the trimless finish to be achieved the fitting must be installed prior to final plastering; a 3 year manufacturer warranty provides added confidence.
