Collingwood H2 Deco CSP Wattage & Colour Switchable Architectural Downlight - All White

A Downlight That Disappears Into a White Ceiling

The Collingwood H2 Deco CSP in all white is built for ceilings where you don't want the fitting to draw attention to itself. The bezel is finished in matching white, so once it's in the ceiling it reads as part of the surface rather than a separate object bolted on top.

The All White Finish

This version pairs a white outer bezel with a white polycarbonate trim around the mild steel body, keeping the whole fitting a single, calm colour from below. It sits flush to the ceiling plane once installed, with sprung clips holding it firmly in the cutout.

How It Works

• Wattage is switchable on site between 6.5W and 10W, so one fitting covers two output levels.
• Colour temperature is also switchable, across 2200K, 2700K, 3000K and 4000K, letting you match the light to the room without ordering a different SKU.
• Output runs from 550 to 1000 lumens depending on the wattage and colour temperature you choose, at a CRI of 80.
• Beam angle is 40 degrees, giving a reasonably wide spread for general room lighting rather than a tight spot.
• The LED is integral, so there's no separate driver to source or fit. It wires straight to the mains and is mains dimmable.
• Cutout size is 72mm to 75mm, with the fitting measuring 85mm in diameter and 68mm in depth.
• Wiring is parallel, and the fitting is Class I, so it needs an earth connection.

Where It Works Best

With an IP65 rating from below, this downlight is rated for bathroom zone 1, so it can go directly over a bath or shower area as well as anywhere drier, like kitchens, hallways and living rooms. If you're planning a bathroom layout, our guide to bathroom lighting zones explains what each zone allows. The white finish and flush fit make it an easy match for white or pale ceilings in both homes and commercial interiors.
