Description The Orbis is a 100mm diameter surface-mount downlight in brushed gold aluminium, designed around a single GX53 bulb fitting. The cylindrical housing sits flush against the ceiling with minimal projection, making it suitable for low-ceiling installations where recessed downlights cannot be fitted. The turned aluminium body carries a brushed gold finish on both the exterior and the interior rim, giving a warm metallic accent when viewed from below. Designed for hallways, cloakrooms, wardrobes and low-ceiling rooms where recessed lighting is impractical, the Orbis provides directed downlight without requiring ceiling void depth. The GX53 fitting accepts compact LED bulbs (sold separately) typically in the 7-11W range, providing focused task light or general illumination depending on bulb choice. The fitting is dimmable when paired with a compatible LED bulb and dimmer switch. The turned aluminium construction acts as a heat sink for the LED bulb, allowing continuous operation without overheating. At 100mm diameter the Orbis occupies a smaller ceiling footprint than most 120-150mm recessed downlights, making it useful for narrow corridor runs or where multiple fittings need spacing on a compact ceiling area. The IP20 rating restricts use to dry indoor locations only — bathrooms and outdoor applications require a higher IP-rated alternative. Specification Diameter (mm) 100 Dimmable Yes Number Of Bulbs 1 Bulb Type GX53 IP Rating IP20 Warranty 5 Years Frequently Asked What bulb does it take? The Orbis uses a GX53 bulb, a compact LED format typically available in 7-11W outputs. Bulbs are sold separately. Choose a warm-white 2700K-3000K LED for general room lighting or a cooler 4000K for task-focused applications. Is it dimmable? Yes, the fitting itself is dimmable when paired with a dimmable GX53 LED bulb and a compatible trailing-edge or leading-edge dimmer switch. Check the bulb packaging for dimmer compatibility before purchase. Can it be used in bathrooms? No. The IP20 rating restricts the Orbis to dry indoor locations only. Bathrooms require IP44 or higher for zones 1 and 2, and IP65 for zone 0. For bathroom downlights in a similar finish, search for IP44-rated alternatives at Niori. What ceiling depth is needed? The Orbis is surface-mounted, so it requires no ceiling void depth. The fitting sits directly against the ceiling surface and projects approximately 35-40mm downwards, making it suitable for solid ceilings or ceilings with minimal void space.
