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

A Bezel That All But Disappears

The H2 Deco CSP is finished entirely in black, bezel and reflector included, so once it's fitted into a dark or matt ceiling there's very little to see beyond the light itself. That makes it a good choice for architectural interiors where the fitting is meant to recede and let the beam do the talking.

Finished in All Black

Both the bezel and the reflector cone are black on this version, rather than pairing a black ring with a paler inner face. That consistency helps the aperture read as a single dark shadow line against the ceiling, rather than drawing the eye with a bright ring around the beam.

How It Works

This is a CSP fitting, meaning both the wattage and the colour temperature are switchable on site rather than fixed at the factory. Choose between 6.5W, which gives 500 to 650 lumens, or 10W, which steps up to 650 to 900 lumens. Colour temperature switches across 2200K, 2700K, 3000K and 4000K, so you can match the tone to the room without ordering a different SKU. Colour rendering is CRI80 and the beam angle is 40 degrees.

The LED is integral, so there's no separate lamp to buy or replace, and it wires straight to the mains with no external driver required. It's mains dimmable, wired in parallel, and needs a ceiling cut out of 68 to 75mm.

Where It Works Best

With an IP65 rating from below and IP20 from above, this downlight is rated for bathroom zone 1 as well as everyday living spaces, kitchens, hallways and stairwells. The commercial lighting classification on this listing also reflects real use in offices, retail and hospitality settings where a discreet black downlight suits a darker ceiling or a feature run of spotlights.

About Collingwood Lighting

Collingwood Lighting has been developing LED technology since 2002, working out of its base in Sywell, Northamptonshire, where its products are designed and manufactured. The CSP switching built into this fitting, wattage and colour temperature both adjustable after installation, is typical of how the brand approaches flexibility within a single SKU rather than a wall of near identical variants. Collingwood also holds a Gold medal from EcoVadis, which places it in the top 5% of companies assessed globally for sustainability.

Questions People Ask

Can I change the wattage after it's installed?
Yes. This is a CSP fitting, so you can switch between 6.5W and 10W on site rather than being locked into one output at the point of manufacture.

Is this the same as buying separate colour temperature versions?
No. One fitting covers 2200K, 2700K, 3000K and 4000K, switchable on site, so you don't need to choose or stock multiple SKUs for different colour temperatures.

Can I use this in a bathroom?
Yes. Rated IP65 from below, it covers bathroom zone 1. The IP20 rating from above means the space behind the ceiling should stay dry.

Do I need a separate driver?
No. It has an integral LED and wires straight to the mains, so there's no external driver to buy or fit.

What size hole do I need to cut?
The ceiling cut out required is 68 to 75mm.
