The Domus CELL-9-5CCT-T90 is a 9 W tiltable LED downlight with five switchable colour temperatures, a 60° beam and an Ø110 mm fascia. Cutout Ø80–85 mm.
⛔ The cutout is Ø80–85 mm — not 90 mm. Despite the name.
This matters more than it sounds. The obvious reading of “T90” is a 90 mm hole, which is the standard Australian downlight aperture — and it is wrong here. Its datasheet gives Ø80–85 mm.
| Model | Name suggests | Actual cutout |
|---|---|---|
| CELL-9-D90 | 90 mm | ✅ Ø90–92 mm |
| CELL-9-T75 | 75 mm | ✅ Ø72–75 mm |
| CELL-9-T90 | 90 mm | ⛔ Ø80–85 mm |
⛔ So it is not a drop-in replacement for a standard Ø90 mm downlight. A hole already cut to 90 mm is too big for this fitting — you want the D90 or DT90 for that. Tell us the hole you have and we will match the fitting to it.
9 W COB LED tiltable downlight, CELL system. Cutout Ø80–85 mm. Ø110 mm fascia, approx. 73 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. ⛔ Despite the "T90" name, the cutout is Ø80–85 mm — it is NOT a drop-in for a standard Ø90 mm hole. ⚠ Our record shows a depth of 61 mm against the sheet's 73 mm; work to 73 mm. ⚠ Lumen output is not recorded. Warranty 3 years.

Ø80–85 mm, from its datasheet — and not the 90 mm the "T90" name implies. That distinction is the most important thing on this page: a hole already cut to the standard Australian 90 mm is too big for this fitting. If you are retrofitting into existing 90 mm holes, you want the D90 or DT90 instead. Tell us the hole you have and we will match the fitting to it.
We do not know, and we are not going to rationalise it. What we can show is that the naming is not a reliable guide across this range: the D90 does take Ø90–92 mm and the T75 does take Ø72–75 mm, but this T90 takes Ø80–85 mm. Read the cutout, not the name.
Because the tilt mechanism sits inside the fascia rather than above the ceiling, so the body passing through the hole is narrower while the visible trim stays wide enough to cover it. That is also why the T-series is shallower — around 73 mm here against 96 mm for the fixed D90, which makes it the better choice in a tight void.
Work to 73 mm, which is the datasheet figure. Our product record shows 61 mm, and the two disagree — if the void is tight, use the larger number and ask us to confirm before you commit.
9 W for standard ceilings, hallways, bedrooms and general residential lighting — it is the more common choice. 13 W for higher ceilings and commercial spaces, or where you want fewer fittings. Note the 13 W T90 records a depth of 100 mm against this one's ~73 mm, so they are not interchangeable in a shallow void.
For a single object, yes — tilting a 60° beam moves a large soft pool rather than placing a defined one. It suits wall washing and general aimed light. For a tight accent, ask us about the bare CELL module in 15° or 24° with a separate frame; that gets the narrow beam and the module stays replaceable.
Yes — that is the point of the CELL system. The 9 W lamp module clicks out, so when it fails or when the colour 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.
