Description

The Phosix is a 274mm linear trimless LED recessed downlight housing ten individual LED modules behind a plaster-in black frame, delivering 20W of 4000K neutral white light. The fitting is designed to sit flush within the ceiling plane with no visible trim or bezel, allowing the ceiling plaster or render to finish right up to the edge of the aperture for a fully integrated appearance.

Built for commercial and high-specification residential projects where ceiling uniformity is required, the Phosix suits modern lobbies, corridors, retail spaces and office zones needing directional task light or linear accent lighting. The ten modules are arranged in a single row, creating a 274mm line of light that can be oriented parallel to walls or furniture runs. The die-cast aluminium housing provides thermal management for the LED array while the black polycarbonate reflector directs light downward at a fixed angle.

The 4000K colour temperature produces a cool white output that sits between warm residential lighting and clinical daylight, making it appropriate for workspaces, galleries and hospitality zones where colour rendering and visibility matter. The IP20 rating limits this fitting to dry indoor environments. Installation requires a ceiling void depth of at least 71mm to accommodate the driver and housing, and the plaster-in frame must be fitted before ceiling finishing work begins.

The Phosix is non-dimmable and ships with the LED modules integrated into the housing, so no separate lamp purchase is required. The 5-year warranty covers the LED array and driver assembly.

Frequently Asked

Can this be used in bathrooms?

No. The IP20 rating means the fitting has no protection against moisture ingress and is only suitable for dry indoor environments. For bathrooms or wet rooms you need a fitting rated at least IP44 or IP65 depending on zone placement.

What ceiling void depth is required?

A minimum 71mm void depth is needed to house the fitting and driver assembly. The plaster-in frame must be installed before ceiling finishing work so the plaster can be brought flush to the aperture edge.

Is the 4000K colour temperature warm or cool?

4000K is neutral white, sitting between warm residential tones (2700K-3000K) and cool daylight (5000K+). It provides good colour rendering for task work and commercial spaces without feeling clinically bright.

Can the LED modules be replaced?

The LED array is integrated into the housing and not user-replaceable. The 5-year warranty covers the LED modules and driver, and Ideal Lux designs the fitting to outlast typical project lifecycles before requiring full replacement.
