The Domus DECO-18 is an 18 W round LED downlight with switchable tri-colour — 3000 K, 4000 K and 5700 K. White or black.

⛔ The cutout is not recorded anywhere, and we will not guess it

This listing has no datasheet, and its record holds no cutout. ⛔ So the one figure you need before cutting a ceiling is in no source we hold.

DECO model Cutout
DECO-8 Ø70–75 mm
DECO-15 Ø120–130 mm
DECO-18 (this one) ⛔ not recorded
DECO-28 Ø200–210 mm
  • ⛔ Do not read a figure off that ladder. The cutout is not proportional to wattage — it roughly triples between the 8 W and the 28 W, so an 18 W could sit anywhere between 130 and 200 mm.
  • ⭐ Ask us and we will get it from Domus before you order. On a recessed downlight this is the one mistake that cannot be undone on site.
  • ⚠ It is not alone. Across 127 recessed Domus products, 20 have a cutout in no source at all and 43 more have it on the datasheet only.
⛔ What else is missing

Its record holds eight fields: voltage, three colour temperatures, wattage, bulb type, application, AC/DC and the colour-changing flag. ⛔ No lumen output. No CRI. No beam angle. No IP rating. No dimensions. No dimming information.

  • ⚠ On a downlight, output and beam angle decide the spacing — how many fittings a room needs and how far apart they go. Neither is recorded.
  • ⚠ And the IP rating decides whether it can go in a bathroom. Its DECO siblings all carry a qualified IP44; ⛔ this one carries nothing, so do not assume it.
  • ⭐ Tell us the room and we will get the full table from Domus.
⭐ What can be said, from the range
  • Tri-colour 3000 / 4000 / 5700 K is recorded, and matches the DECO range's switchable pattern — ⭐ set by a dip switch at the back of the fitting on every other DECO, so expect the same here and set it before installation.
  • 240 V AC.
  • ⚠ The DECO range is characterised by a deep-set frame to cut glare and an ultra-slim housing for shallow ceilings. Those are range descriptions and not this listing's own, so we have not put a housing depth in the specification.
  • ⚠ DECO dimming is “tested on the Domus dimmer series” across the range. Whether this model dims at all is not recorded.
Where it works
  • General ceiling lighting at a mid output, between the DECO-15 and the DECO-28.
  • Living areas, offices and hallways, once the beam angle is confirmed.
  • ⛔ Not until the cutout is confirmed with us — nothing else about the installation can be planned without it.
  • ⚠ Not in a bathroom or laundry until the IP rating is confirmed.
Specifying it

18 W round LED downlight, tri-colour 3000 / 4000 / 5700 K. 240 V AC. White or black. ⛔ No datasheet exists for this listing, and the cutout, lumen output, CRI, beam angle, IP rating and dimensions are recorded in no source. ⛔ Do not interpolate the cutout from the DECO-15 and DECO-28 — the ladder is not proportional to wattage. Ask us and we will get the figures from Domus before you order. ⛔ Warranty not recorded.

Questions
What size hole does it need?

Not recorded anywhere — this listing has no datasheet and its record holds no cutout, so the one figure you need before cutting a ceiling is in no source we hold. And do not interpolate it from the range: the DECO-8 takes Ø70–75mm, the DECO-15 takes Ø120–130mm and the DECO-28 takes Ø200–210mm, which is not proportional to wattage — it roughly triples between the 8W and the 28W. An 18W could sit anywhere between 130 and 200mm. Ask us and we will get it from Domus before you order.

How bright is it?

Not recorded, and with no datasheet the figure is in no source we hold. For context, the DECO-15 gives 1,300–1,440lm and the DECO-28 gives 2,300–2,400lm, so an 18W would sit between them — but that is a comparison with the range rather than a figure for this product, which is why it is not in the specification table. Tell us the room and we will get the real output from Domus.

Can it go in a bathroom?

Ask us first. No IP rating is recorded on this listing at all. Its DECO siblings carry IP44 qualified as "from the underside once installed into the ceiling", but that is their rating, not this one's, and we would rather check than have you install something into a wet area on an assumption.

Can it be dimmed?

Not recorded. Across the DECO range dimming is offered with the qualifier "tested on the Domus dimmer series; may work on others but not tested", but whether this model dims at all is not stated on the listing. If dimming is part of the design, settle it with us before ordering rather than after.

How many will I need for a room?

That depends on the output and the beam angle, and neither is recorded — which is exactly why we cannot answer it from the page. On a downlight those two figures decide the spacing: how many fittings a room needs and how far apart they go. Tell us the room dimensions and ceiling height and we will get the full table from Domus and lay it out with you.

Which colour temperature should I choose?

Three are switchable — 3000K, 4000K and 5700K — and that much is recorded. For living areas and bedrooms, 3000K. For kitchens, bathrooms and workspaces, 4000K. 5700K is a working light and looks stark at home. Every other DECO sets this with a dip switch at the back of the fitting, so expect the same here and set it before it goes into the ceiling.

Should I choose this or the DECO-15?

On what is recorded, the DECO-15 is the better documented choice: it has a verified datasheet giving a Ø120–130mm cutout, 1,300–1,440lm, CRI ≥80, a 100° beam and 50,000 hours. This DECO-18 has none of that in any source. If the extra 3W matters, ask us and we will get the DECO-18 figures so you can compare properly — but if you need to specify today, the DECO-15 is the one you can plan from.
