    The Range

    Named for one of the brightest stars in the galaxy.

    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.

    Why Rigel

    Designed for projects, built to disappear

    Visual comfort first

    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.

    High output, small aperture

    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.

    Plaster-in trimless install

    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.

    Fire-rated, certified

    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.

    Three apertures, one stock line

    Round 40, Square 40, Round 50 — all share the same LED engine, lens, and driver components. One light source family, three architectural languages.

    In stock, dispatched same day

    All 16 complete downlight variants and replacement components held in UK stock. Orders placed before 3pm dispatch the same day from our Wandsworth warehouse.

    See It Apart

    Engineered for the ceiling

    Exploded assembly · Frame, module, lens and insert

    Compact enough to hold between two fingers.

    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.

    Components & Spares

    Build your own, or replace a part

    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.

    LED Modules

    Light engines available in 7W or 9W, 2700K or 3000K. CRI 90+, 25,000-hour rated.

    Lenses

    Click-fit interchangeable lenses for fixed and adjustable inserts. Four beam angles available.

    Frames & Inserts

    The structural fire-rated housing plus the visible aperture insert. Replaceable from below the ceiling without re-plastering.

    Drivers & Removal Tools

    10W constant-current drivers in Triac and DALI variants, plus the removal tools that ship with every order.
