Robus Ultimatum Express Flat Downlight 4/6W CCT IP65 White

The Robus Ultimatum Express Flat Downlight 4/6W CCT IP65 White is a slim, contractor-friendly downlight built for projects where you need reliable fire integrity, moisture protection and clean, modern light output. With a shallow 71mm depth and a flat white finish, it’s well suited to refurbishments and new installs across kitchens, bathrooms, hallways and commercial spaces where ceiling void is limited.

Selectable wattage and colour temperature for on-site flexibility

To simplify spec changes and reduce stockholding, the fitting features wattage selection (4W or 6W) via a switch on the rear, plus CCT selection (3000K / 4000K / 6000K) to suit the room’s ambience—from warm white for living areas to cooler light for task-focused spaces. High-quality Osram LEDs and an LEDchroic lens replicate the look of halogen dichroics, delivering uniform, shadow-free illumination.

Certified fire performance with quick, secure wiring

Tested to fire resistance standards including EN 1365-2 and EN 1363-1, this downlight is suitable for 30/60/90-minute ceiling constructions, including solid timber joists, I-joists and metal web joists, and is also fire, moisture and acoustic rated. Installation is made quicker and safer with a market-leading quick release 2-part connector and colour-coded lever terminals, while dimming compatibility includes selected trailing-edge and a wide range of leading-edge dimmers.
