Domus THOR-PRO 15W TRIO Dim 36° Recessed

The Domus THOR-PRO-15 is a recessed adjustable LED downlight — 15 W, 240 V AC, CRI ≥90, 36° beam standard, switchable 3000/4000/5000 K, in white or black.

⛔⛔ Four of its fields contradict its own family

• ⭐ WE CHECKED ALL 16 THOR-PRO LISTINGS. ⭐ This is the only one publishing 12 V, the only one publishing RGB, and the only one publishing stainless steel. ⭐ Its own siblings — the 15 W surface mount and the 15 W track head, which are the same light in a different body — carry none of them.
• ⭐⭐ SO IT IS ONE RECORD, NOT A CONVENTION — ⭐ which makes it a single correction rather than a policy question.
• ⭐ THE VOLTAGE ONE IS THE MOST CONSEQUENTIAL. ⚠ A downlight recorded as 12 V DC implies a driver and low-voltage cabling that this fitting does not need — it takes mains directly. ⭐ Anyone estimating from the record would price transformers that are not required.
• ⭐ THE RGB ONE WOULD MISLEAD DIFFERENTLY: this is a fixed-white downlight with three switchable temperatures. ⭐ It does not produce colour. ⭐ Someone filtering for RGB fittings would find it and be disappointed.
• ⭐ WE HAVE PUBLISHED THE FAMILY'S FIGURES THROUGHOUT.

⭐ 15 W and CRI ≥90 — the size that suits most retail

• ⭐ 1,200 to 1,300 lumens in white, 1,150 to 1,300 in black. ⭐ NOTE THAT THE BLACK PENALTY HERE IS ONLY ABOUT 1.4% — ⚠ where the 23 W model in the same housing loses 13.9%. ⭐ On this one, choose the finish on appearance.
• ⭐⭐ 15 W IS USUALLY THE RIGHT STARTING POINT FOR RETAIL DISPLAY. ⭐ From a 3 m ceiling onto a shelf or table, 1,300 lumens in a 36° beam gives a bright, distinctly lit pool without the harshness of a larger fitting. ⭐ Step up to 23 or 32 W where the ceiling is higher or the surface is genuinely large.
• ⭐ CRI ≥90 is the specification that matters more than the wattage in a shop — ⭐ it is what makes stock look like itself.

⭐ Five beam angles, and how to choose

• ⭐ 15°, 24°, 36°, 45° and 60°, with 36° standard. ⭐ Most downlights offer one.
• ⭐ 15° is a spot for a single object; 24–36° is display lighting for a shelf bay or a counter; 45–60° is general lighting.
• ⭐ FROM A 3 m CEILING TO A 1 m SURFACE, a 36° beam lights a circle about 1.3 m across and a 60° beam about 2.3 m. ⭐ Choose from the object, not the room.
• ⚠ The narrow angles are unforgiving. ⭐ A 15° beam that is 10° off misses its subject entirely, so it suits fixed displays rather than ones that get rearranged.

⭐ Recessed, and the case for it over the surface version

⭐ Recessed is the discreet option: the fitting disappears into the ceiling and only the light is seen, which in a high-end retail or residential space is usually the point. ⭐ THE SURFACE AND TRACK VERSIONS OF THE SAME HEAD EXIST FOR CEILINGS THAT CANNOT BE CUT — ⭐ concrete, fire-rated, or full of services. ⭐ Since all three share the same 62 mm cover and 170 mm housing, a fitout can mix them freely and the light stays identical. ⚠ Check the ceiling void depth before specifying recessed: 170 mm of housing needs somewhere to go.

✅ What is published

Where it works

• ⭐ Retail display from a 3 m ceiling — ⭐ the right size.
• ⭐ High-end residential — ⭐ recessed disappears.
• ⭐ Either finish — ⭐ only 1.4% between them here.
• ⚠ Not in a shallow ceiling void — ⭐ 170 mm deep.
• ⚠ Not at 15° on a display that gets rearranged.

Specifying it

Recessed adjustable LED downlight. 15 W at 240 V AC. White 1,200/1,300/1,250 lm; black 1,150/1,300/1,250 lm. 3000/4000/5000 K switchable. CRI ≥90. Beam 15°, 24°, 36°, 45° or 60° (36° standard). 62 mm cover, 170 mm CNC aluminium housing. Dimmable, flicker-free. IP20. 50,000 hrs. ⛔⛔ FOUR OF ITS FIELDS CONTRADICT ITS OWN FAMILY — 12 V, DC, Stainless Steel and RGB, on a 240 V AC aluminium fixed-white downlight. Across all 16 THOR-PRO listings this is the only one publishing any of them, so it is a single record to correct rather than a convention. ⭐ THE VOLTAGE IS THE CONSEQUENTIAL ONE: a downlight recorded as 12 V DC implies a driver and low-voltage cabling this fitting does not need, and anyone estimating from the record would price transformers that are not required.
