The Domus DEEP-13 is a 13 W deep-set tiltable LED downlight in black or white — COB with a reflector, CRI above 80, a 36° beam, switchable 3000 K / 4000 K / 5000 K and a Ø90 mm cutout. ⚠ A note on the name. This is listed as Deep-12 and rated 12 W in the title, but the model is DEEP-13 and every other source — the datasheet, the product record, and the item numbers in the sheet's own table — says 13 W. We have published the 13 W figures here and flagged the title for correction. If you are calculating a circuit load, use 13 W. What “deep set” actually buys you This is the whole point of the fitting and it is worth understanding before you compare it on price: The LED sits recessed well back inside the housing, behind a reflector. From a normal standing or sitting position you cannot see the source — you see a lit surface, not a bright dot. That kills the glare that makes cheap downlights uncomfortable in a room you actually sit in. The cost is a narrower beam: 36°, against the 90° of a flat-faced downlight. This is a focused light, not a wash. ✅ So: use more of them, closer together. A 36° beam from a 2.4 m ceiling lands a pool roughly 1.5 m across — plan on about 1.2–1.5 m spacing for even coverage, not the 2 m you might use with a wide-beam fitting. And it tilts The head is adjustable, which with a 36° beam is what makes it genuinely useful: Wash a wall — a row set back from the wall and angled at it turns the wall into the light source and makes a room feel larger. Light art, joinery or a splashback — a focused beam on the thing you want seen. Aim around a beam or a rafter in a raked ceiling. ⚠ Aim them at night, before the ceiling is patched. Tiltable downlights are routinely installed and never adjusted. The numbers a specifier needs 987 lm at 3000 K, 1,053 lm at 4000 K, 1,120 lm at 5000 K — output rises as the colour gets cooler, which is normal and worth knowing if you are counting lumens for a room. 81 lm/W at the 4000 K setting. CRI above 80, 50,000 hours. Cutout Ø90 mm, face Ø100 mm, height 94 mm — that height is the deep-set housing, and it needs the room above. IP40 — dust protected, no water rating. Not for a shower, not for an eave. For a wet area, ask us about the AQUA at IP65. Dimming: yes, with a suitable dimmer. It comes complete with its LED driver and a flex-and-plug, so the electrician is not sourcing a driver. ⚠ LED dimming compatibility is where problems live — tell us the dimmer you plan to use, or ask us for one matched to it, and get it right before installation rather than after. The colour is set on a dip switch at the back of the fitting, so it is chosen before it goes into the ceiling. Decide first, and set every fitting in a room the same. Where it works Living rooms and bedrooms — the deep-set housing is why it is comfortable to sit under. Wall washing and accenting joinery or art, using the tilt. Hallways and stairs, where glare is most noticeable. ⚠ Space at 1.2–1.5 m — a 36° beam is focused, not a wash. ⚠ IP40 — not for bathrooms, eaves or anywhere wet. Specifying it Cutout Ø90 mm, face Ø100 mm, height 94 mm. 13 W COB LED giving 987 / 1,053 / 1,120 lm at 3000 K / 4000 K / 5000 K, set on a dip switch before installation; CRI >80, 36° beam, 50,000 hrs. Tiltable. Dimmable with a suitable dimmer; supplied with its LED driver and flex-and-plug. 220–240 V AC, IP40 — dust protected, no water rating. Warranty 3 years. Supplied and supported by Lights For You. Questions Is it 12 watts or 13?Thirteen. The title says Deep-12 and 12 W, but the model is DEEP-13 and the datasheet, the product record, the sheet’s own item table and its own description all say 13 W. We have published the 13 W figures and flagged the title. If you are calculating a circuit load, use 13 W. What does "deep set" mean?The LED sits well back inside the housing behind a reflector, so from a normal standing or sitting position you cannot see the source — you see a lit surface rather than a bright dot. That is what kills the glare that makes cheap downlights uncomfortable in a room you actually sit in. How far apart should I space them?About 1.2 to 1.5 metres, not the 2 metres you might use with a wide-beam fitting. The trade-off for the deep-set housing is a narrow 36° beam, which from a 2.4 m ceiling lands a pool roughly 1.5 m across. Use more of them, closer together. What is the tilt for?Aiming. A row set back from a wall and angled at it turns the wall into the light source and makes a room feel larger; a focused beam on art, joinery or a splashback shows it properly. Aim them at night before the ceiling is patched — tiltable downlights are routinely installed and never adjusted. Can it go in a bathroom?No. It is IP40 — dust protected with no water rating — so it is not for a shower, a wet area or an eave. Ask us about the AQUA range at IP65 for those. Can I dim it?Yes, with a suitable dimmer, and it comes complete with its LED driver and a flex-and-plug so your electrician is not sourcing one. LED dimming compatibility is where problems live, so tell us which dimmer you plan to use — or ask us for a matched one — and get it right before installation. When do I choose the colour temperature?Before it goes into the ceiling. The selector is a dip switch on the back of the fitting. Decide first and set every fitting in a room the same.
