Rigel Trimless LED downlights—fire-rated, trimless plaster-in fittings in Round 40, Square 40 and Round 50. Modular range with fixed, adjustable and wall-washer beam options.
The Rigel Series delivers powerful illumination from a fitting compact enough to be held between two fingers. Trimless, fire-rated, and engineered with a unique 36° cut-off optic, each fixture blends seamlessly into the ceiling while providing the soft, comfortable light specifiers expect at the upper end of the residential and commercial market.
Three apertures — Round 40, Square 40 and Round 50 — each available with fixed, adjustable or wall-washer optics, and 7W or 9W modules. Sixteen complete fittings to choose from, all sharing the same plaster-in frame and 90+ CRI light source.
A 36° cut-off angle on the fixed optic, 41° on the adjustable. UGR < 19 across the range, suitable for environments where glare ratings matter — offices, retail, and hospitality.
Up to 1082 lumens from a 42mm fitting at 9W — with a 7W variant for shallower ceiling voids, allowing a consistent visible aperture across rooms with different structural depths.
The pierced petal flange is designed to plaster directly into the ceiling, leaving no visible trim. The aperture sits flush in the plasterwork — clean, architectural, no compromise.
60-minute fire rating, IP54 protection on fixed inserts and IP44 on adjustable, with CRI 90+ across every module. Meets Part B and Part L expectations on residential refurbishments.
Round 40, Square 40, Round 50 — all share the same LED engine, lens, and driver components. One light source family, three architectural languages.
All 16 complete downlight variants and replacement components held in UK stock. Orders placed before 3pm dispatch the same day from our Wandsworth warehouse.
Despite their small size, Rigel downlights deliver high lumen output — up to 1082lm from a 42mm aperture. The compact light engine and shallow ceiling depth requirement make them suitable for refurbishment projects where ceiling void is at a premium.
For the customer: one clean aperture, one fitting. For the installer: serviceable parts that swap without disturbing the ceiling finish.
Pick your base, then build it step by step. We'll match your selection to a pre-built kit if one exists — or list the components you need to add to your basket for a custom build.
Three optic options with different IP ratings. Wall Washer ships with a built-in asymmetric optic — no separate lens needed.
Each base is offered with multiple optic and wattage combinations, all sharing the same plaster-in frame and 90+ CRI light source.
Trimless miniature round downlight, fire-rated, 42mm aperture. Six complete variants across fixed, adjustable and wall washer optics.

Every Rigel fitting is assembled from interchangeable components — modules, lenses, frames, inserts and drivers — all available individually.
A Rigel downlight is built from five swappable parts: a frame, an LED module, a lens, an insert (the visible aperture), and a driver. Buy them as a complete kit, or piece by piece for service and customisation.
Light engines available in 7W or 9W, 2700K or 3000K. CRI 90+, 25,000-hour rated.
Click-fit interchangeable lenses for fixed and adjustable inserts. Four beam angles available.
The structural fire-rated housing plus the visible aperture insert. Replaceable from below the ceiling without re-plastering.
10W constant-current drivers in Triac and DALI variants, plus the removal tools that ship with every order.
From hospitality and retail to high-end residential refurbishments, Rigel disappears into the ceiling, leaving only the light. Below, a few projects that show what it looks like in real spaces.
