Collingwood H2 Pro Lumen and Colour Switchable - Fixed - 5W or 7W (Bezel Sold Separately)

One Downlight, Three Jobs Done

The H2 Pro is a fixed recessed downlight that changes its own output. A pair of switches on the back of the driver let you pick the wattage and the colour temperature once the ceiling is already cut, so one box on site covers jobs that would otherwise need several different downlights ordered in advance.

The Engine, Not the Finish

This listing is for the light engine itself. The bezel is sold separately, so you can pick the ring finish once you know how the room is coming together, rather than committing to a look before the plaster is even dry.

How It Works

• Switch to 5W for 550 lumens at 2700K, or 650 lumens at 3000K and 4000K
• Switch to 7W for 750 lumens at 2700K, or 850 lumens at 3000K and 4000K
• Works out at 107 to 130 lumens per watt depending on the setting you choose
• 55 degree beam angle from a 64 to 72mm cutout
• Driver built into the fitting, wired via a 2 part easy fit connector in parallel
• Mains dimmable, with no separate driver to source or fit

Where It Works Best

Because the wattage and colour temperature can both be changed after fitting, the H2 Pro suits rooms where the brief might shift, a kitchen that gets busier once the units go in, a bedroom that wants to be warmer at night and brighter in the morning, a hallway that doubles as a home office.

It's fire rated with I-joist approval, so it can go straight through insulated ceilings without a fire hood or extra enclosure, which matters as much in a loft conversion as it does in a straightforward refurb.

It's IP65 rated at the front, so it also covers bathroom zone 1, kitchens, and anywhere else that gets the occasional splash. For more on which fittings suit which part of a bathroom, see Moonlight's guide to bathroom lighting zones.

Collingwood Lighting

Collingwood Lighting designs and manufactures its LED products from Sywell in Northamptonshire, and has focused on LED technology since 2002. The brand states it was among the first to bring fire rated, fully sealed for life, and mains dimmable LED fittings to the UK electrical wholesale market, a claim that lines up with fittings like the H2 Pro, built to go straight into damp or insulated ceilings with no extra steps. Collingwood 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 the colour temperature be changed after it's been fitted?
Yes. The colour temperature switch sits on the back of the driver, so it can be changed at any point after installation, not only during the initial wiring.

Does the H2 Pro need a separate driver?
No. The driver is built into the fitting itself, so there's nothing extra to source or fit inside the ceiling void.

Is this downlight suitable for a bathroom?
Yes. It's IP65 rated at the front, which covers bathroom zone 1 as well as kitchens and other rooms where splashes are likely.

Do I need to buy anything else to install it?
Yes. The bezel is sold separately, so a matching bezel needs to be chosen in the finish you want before fitting.
