Collingwood H4 Lite CSP Downlight - Matt White Bezel

A Downlight That Adjusts To The Room, Not The Other Way Round

Most recessed downlights lock you into one wattage and one colour temperature from the day they're installed. The Collingwood H4 Lite CSP does the opposite. Switches built into the fitting let you choose between 4W and 6W output, and between warm white, cool white or daylight, without touching any wiring. It's a genuinely useful fix for anyone who isn't completely sure yet how a room should feel once the plaster dust has settled.

The Matt White Bezel

This version has a matt white bezel, a plain, low profile ring that sits flush against a white or light coloured ceiling and quietly disappears rather than drawing attention to itself. The main body is mild steel with V0 rated, fire resistant plastic components, and the complete fitting weighs a modest 257 grams. The head itself tilts within the housing, so the beam can be angled rather than left pointing straight down. If a metallic or dark finish suits the room better, Collingwood also makes this fitting with a brushed steel or a matt black bezel.

How It Works

• Switches on the fitting set the wattage, 4W or 6W, and the colour temperature, warm white, cool white or daylight, so the choice is made once at installation rather than through an app or a remote.
• The head tilts within the bezel, letting you graze a wall or angle light over a worktop instead of pointing it straight down.
• A 70 to 72mm cutout and parallel wiring keep it consistent with standard multi fitting downlight circuits.
• It's mains dimmable using a leading edge or trailing edge dimmer, and CRI is rated above 80, so colours under it stay reasonably true rather than washed out.

Where It Works Best

Being able to switch the colour temperature after fitting makes this a sensible choice anywhere you're not entirely sure whether you want a cooler, more functional light or a warmer, more relaxed one. That covers kitchens, home offices, hallways and open plan living spaces that need to do a bit of both. It's rated IP65 from below, which places it in bathroom zone 1, so it's equally at home above a shower enclosure or a bath.

Collingwood Lighting

Collingwood Lighting designs and manufactures its LED products from Sywell in Northamptonshire, and has specialised purely in LED technology since 2002. Collingwood says it was among the first to bring fire rated, fully sealed for life, and mains dimmable LED downlights to the UK electrical wholesale market, which is exactly the combination built into the H4 Lite CSP. The company has also been awarded a Gold medal by EcoVadis, placing it in the top 5% of companies assessed globally for sustainability.

Questions People Ask

• Can it be dimmed? Yes, using a mains leading edge or trailing edge dimmer switch.
