The Domus CELL-9-5CCT-D75 is a 9 W fixed LED downlight with five switchable colour temperatures, a 60° beam and an Ø85 mm fascia, 96 mm deep.
⚠ This is the one CELL fitting whose cutout we cannot confirm from its own datasheet — so ask us before you cut.
What the rest of the range gives: the D90 and DT90 take Ø90–92 mm, the T75 takes Ø72–75 mm, and the T90 takes Ø80–85 mm. ⛔ The sheet attached to this listing is the CELL-9 module's, and its cutout line describes a rectangular SLOTCELL frame — a different product.
✅ What can be said with evidence: Domus sells a separate CELL-D75 frame, whose own title and record state a Ø75 mm cutout. This fitting carries the same D75 designation, so Ø75 mm is the strongly likely figure — but we are presenting it as evidence rather than as fact, because the T90 in this same family proves the naming is not always a reliable guide.
Tell us and we will confirm the aperture with Domus in writing before you cut.
| D75 (this) | D90 | |
|---|---|---|
| Fascia | Ø85 mm | Ø100 mm |
| Cutout | ⚠ likely Ø75 mm — confirm with us | ✅ Ø90–92 mm |
| Depth | 96 mm | 96 mm |
| Choose it for | A new ceiling, smaller aperture | ✅ Retrofit into a standard hole |
✅ If you are replacing existing downlights, the D90 is the safer choice — its cutout is confirmed and it matches the common Australian hole.
9 W COB LED fixed downlight, CELL system. Ø85 mm fascia, 96 mm deep. Beam 60°. Five switchable colour temperatures — 2700 / 3000 / 4000 / 5000 / 5700 K, by dip switch. CRI ≥80, dimmable, 50,000 hrs, 200–240 V. Black or white. ⚠ IP44 from the underside once installed.
⛔ Cutout is not confirmed by this fitting's own datasheet. The separately sold CELL-D75 frame states Ø75 mm, and this fitting shares that designation — strong evidence, but ⚠ the T90 in this same family is named for 90 mm and takes Ø80–85 mm, so we are not treating a name as a specification. We will confirm with Domus in writing before you cut. ⚠ Lumen output is not recorded. Warranty 3 years.

Ask us and we will confirm in writing before you cut. The separately sold CELL-D75 frame states a Ø75 mm cutout and this fitting shares that designation, which is strong evidence — but we are not calling it a specification, because the CELL-9-T90 in this same family is named for 90 mm and actually takes Ø80–85 mm. Within this range, the number in the name is not always the aperture.
Because their datasheets give it and this one's does not. The sheet attached to this listing is the CELL-9 module's, and its cutout line describes a rectangular SLOTCELL frame — a different product. The D90, DT90, T75 and T90 all have sheets that state their own apertures; this one does not.
The D90 if you are replacing existing downlights — its cutout is confirmed at Ø90–92 mm, which is the common Australian hole, so it needs no patching and no guesswork. The D75 on a new ceiling where a smaller aperture reads tidier, and once we have confirmed its cutout. Both are 96 mm deep with the same five colour temperatures.
No — this is the fixed version and it fires straight down, which is correct for general ceiling lighting: it seals better and stays aligned in a run, where tilt heads drift out of true over time. The T75 is the tiltable option at a similar aperture, and it is 25 mm shallower at 71 mm, which is worth knowing if the void is tight.
60° on the assembled fitting. The bare CELL module is also sold in 15°, 24° and 36°, so if you need a narrower beam you can either order a module with a separate frame, or swap the module later — because it clicks out without touching the ceiling.
A 2700 K setting at the warm end, which almost nothing else in this catalogue offers — most switchable fittings start at 3000 K. In a bedroom or a hospitality space that is a visible difference. It is set by dip switch before installation, so set every fitting on a circuit the same way.
Yes. CELL is a module-and-frame system and the 9 W lamp module clicks out, so when it fails — or when the colour or beam needs changing — the frame and the ceiling stay untouched. On a larger job it is worth asking us to quote spare modules alongside the fittings.
