Description The Orbis is a 100mm round surface-mounted downlight with a white powder-coated aluminium body and a single GX53 bulb fitting. The cylindrical housing sits 40mm proud of the ceiling, directing light downwards through a recessed aperture. The turned aluminium construction provides thermal management for the LED while the powder-coated finish resists marking and discolouration over time. Designed for surface mounting where recessed downlights are impractical — concrete ceilings, shallow voids, below-floor installations in flats and apartments — the Orbis provides focused task lighting over kitchen worktops, bathroom vanities, hallways and retail display areas. The white finish blends with light-coloured ceilings and the minimal 100mm diameter keeps the visual footprint small. The GX53 bulb format uses a twist-lock fitting that makes bulb replacement straightforward without tools. The downlight is dimmable when paired with a compatible GX53 LED bulb and appropriate dimmer module, allowing light levels to be adjusted for different times of day or activity. The IP20 rating restricts use to dry indoor locations away from direct water contact. The 5-year warranty covers the fitting itself; the GX53 bulb is a user-replaceable consumable sold separately.

The Orbis takes a GX53 bulb with a twist-lock base. GX53 bulbs are sold separately. Choose an LED version between 5-9W for typical task lighting applications. The fitting is dimmable when paired with a dimmable GX53 LED and compatible dimmer. Is it suitable for bathrooms? The IP20 rating means the fitting is suitable only for dry indoor locations away from direct water contact. It is not rated for use in bathroom zones where splashing or humidity is present. Can it be recessed into the ceiling? No. The Orbis is a surface-mounted downlight designed to sit on top of the ceiling surface. It's intended for installations where cutting a recess is impractical, such as concrete ceilings or shallow voids. What is the projection from the ceiling? The cylindrical housing sits approximately 40mm proud of the ceiling surface once installed, directing light downwards through the recessed aperture at the base.
