The Domus DECO-13 is a 13W deep-set LED downlight inround or square, white, black or chrome anultra-slim 38mm housing with a 90 beam,switchable 3000K / 4000K / 5700K and a90mm cutout.

Two things the datasheet says that our page never did, and bothchange a specification decision.

• The IP44 rating applies from the UNDERSIDE, once installed into the ceiling. It isnot a sealed fitting you can put anywhere the protection is what the room sees after thedownlight is in place. Your electrician still works to the zones in AS/NZS3000, and for a genuinewet area ask us about the AQUA at IP65.
• Dimming is tested on the Domus dimmer series. The datasheet says plainly that itmay work on others but has not been tested. That is a weaker claim thandimmable, and it is the difference between a smooth install and a flickeringone.

Tell us the dimmer you intend to use before you order and we will tell youwhether it is a tested pairing.

Slim housing, deep-set face an unusual combination

Most anti-glare downlights are deep, because the recess is what hides the source. The DECO managesboth:

• Only 38mm high. That is genuinely shallow, and it is the reason to choosethis fitting concrete ceilings, minimal roof space, second storeys with shallow battens, andrenovations where the ceiling void is not what you hoped.
• Deep-set frame reducing glare from the source, in the depth available.
• 90 beam a wide distribution, unlike the 36DEEP-13. This is a general room light: fewer fittings, further apart. Plan on roughly2m spacing from a 2.4m ceiling.

Round or square, and three finishes

Both shapes take the same 90mm cutout, so the choice is purely visual and youcan even mix them across a house without changing the ceiling work.

• Round the default, and it disappears fastest into a ceiling.
• Square reads as deliberate, and lines up with square vents, skylights andjoinery.
• White vanishes; black reads as a considered detail on a whiteceiling and hides the aperture; chrome suits bathrooms with chrome tapware.

The numbers

• 800lm at 3000K, 850lm at 4000K, 900lm at 5700K.
• 65lm/W at 4000K modest, and the price of the slimdeep-set housing.
• CRI above 83, SMD LED, 50,000 hours.
• Cutout 90mm, face 110mm, height38mm.
• 5700K is the top setting, not 5000K colder and bluer than youmay expect. Set on a dip switch at the back, before installation.

Supplied complete with a dimmable LED driver and flex-and-plug.

Where it works

• General room lighting a 90 beam, about 2m apart.
• Shallow ceilings, concrete soffits and renovations only 38mm deep.
• Living areas, bedrooms, hallways and kitchens.
• IP44 from the underside once installed for a real wet area ask about the AQUA.
• Dimming tested on Domus dimmers only tell us yours before ordering.

Questions

Which dimmer works with it?

The datasheet is specific and our page was not: dimming is tested on the Domus dimmer series, and it “may work on others but has not been tested”. That is a weaker claim than simply “dimmable”. Tell us the dimmer you intend to use before you order and we will tell you whether it is a tested pairing it is much easier to settle before installation than after.

Can it go in a bathroom?

Carefully. The IP44 rating applies from the underside once the downlight is installed into the ceiling it is not a sealed fitting you can put anywhere. Your electrician works to the zones in AS/NZS 3000, and for a genuine wet area, above a bath or an alfresco ceiling, ask us about the AQUA at IP65.

Will it fit a shallow ceiling?

Yes this is the reason to choose it. At 38mm high it suits concrete ceilings, minimal roof space, second storeys with shallow battens and renovations where the void turned out smaller than hoped. Most anti-glare downlights are much deeper.

How far apart should I space them?

About 2 metres from a 2.4m ceiling. The 90 beam is a wide distribution, so this is a general room light fewer fittings, further apart. That is the opposite of the deep-set DEEP-13, whose 36 beam wants 1.2 to 1.5m.

Round or square?

Purely visual both take the same 90mm cutout, so you can even mix them across a house without changing the ceiling work. Round disappears fastest into a ceiling; square reads as deliberate and lines up with square vents, skylights and joinery.

Is the top setting 5000K?

No 5700K, which is colder and bluer than 5000. It is set on a dip switch at the back of the fitting before installation, so decide before your electrician puts them in, and set every fitting in a room the same.

Which finish should I choose?

White vanishes into a ceiling. Black reads as a considered detail and hides the aperture. Chrome suits bathrooms with chrome tapware.
