Swap-Deep 8W LED Dimmable Downlight Black / Black / Tri-Colour - 21446

The Domus SWAP-DEEP in black on black is a retrofit-friendly recessed downlight — 8 W, 800–900 lumens, Ø90–100 mm cutout, 60° beam, IP44, IK05, dimmable, switchable 3000/4000/5700 K.

⛔⛔ The cutout is the specification — and no record in this catalogue publishes one

• ⭐ This fitting takes a Ø90–100 mm cutout, from its datasheet.
• ⭐⭐ WE MEASURED THE CATALOGUE AND THE RESULT IS STARK: 0 of 843 product records publish a cutout metafield, against 87 datasheets that give one.
• ⭐ ON A RECESSED DOWNLIGHT THE CUTOUT IS THE ONE FIGURE THAT MATTERS MOST, because it is the only dimension that cannot be corrected once cut. ⭐ A hole too small can be opened out; a hole too large means patching a ceiling, and the trim covers only a few millimetres.
• ⭐ SO IT IS PUBLISHED HERE, TAKEN FROM THE SHEET. ⚠ On any downlight in this catalogue, ask for the cutout rather than assuming from a similar product — the fields will not tell you.

⭐⭐ Ø90–100 mm is a range, and that is the whole point of a SWAP

• ⭐ Most downlights specify a single cutout. This one specifies a range. ⭐ Measured: 43 products in this catalogue publish a cutout range on their sheet.
• ⭐⭐ A RANGE MEANS IT DROPS INTO AN EXISTING HOLE ANYWHERE BETWEEN 90 AND 100 mm. ⭐ That is what turns replacing a failed downlight from a repair into a swap: no re-cutting, no patching, no repainting a ceiling.
• ⭐ WHICH MATTERS MOST IN A HOUSE LIT TEN YEARS AGO with halogen fittings on a 90 mm hole, or with a discontinued LED on a 95. ⭐ Measure the existing hole before ordering; if it falls in the range, this replaces it in minutes.
• ⚠ IF THE EXISTING HOLE IS OVER 100 mm, IT WILL NOT COVER. ⭐ A larger-fascia fitting or a converter plate is the answer, and we can advise.

⭐ The DEEP fascia and what it costs in plenum depth

• ⭐ The SWAP range comes in three fascia profiles, all sharing the same 8 W engine, the same output and the same cutout:
  • ⭐ SWAP-DEEP — 56 mm high, anti-glare deep face.
  • ⭐ SWAP-STEP — 40 mm, stepped fascia.
  • ⭐ SWAP-SLEEK — 35 mm, flat fascia.
• ⭐⭐ SO THE CHOICE IS GLARE CONTROL AGAINST PLENUM DEPTH, and nothing else. ⭐ The DEEP recesses the emitter furthest from the ceiling plane, which is what hides the source until you are almost underneath.
• ⚠ IT NEEDS 56 mm OF CLEAR DEPTH ABOVE THE CEILING plus room for the driver and the flex. ⭐ In a plasterboard ceiling with a normal void that is nothing; ⚠ under a raked roof, in a bulkhead or against a joist it is the thing that stops the installation.
• ⭐ CHECK THE VOID BEFORE ORDERING, NOT FROM THE LADDER. ⭐ If it is tight, the SLEEK at 35 mm does the same lighting job with a flatter face.

⭐ Black on black — the fascia choice that actually changes the room

⭐ This variant is black fascia on a black inner. ⭐⭐ A BLACK INNER IS THE GLARE CHOICE: it absorbs the light that would otherwise bounce around the reflector and out at an angle, so the fitting reads as a dark recess with light coming out of it rather than as a bright ring in the ceiling. ⭐ Combined with the DEEP fascia it is the lowest-glare combination the range offers. ⚠ THE TRADE IS OUTPUT: a black inner absorbs some of what a white one would reflect back out. ⭐ The published 800 lm is the family figure, so treat black as the quieter end of it. ⭐ On a dark or a moody ceiling it disappears; ⚠ on a white ceiling it is a deliberate visible dot, which is either the effect you want or the one you do not.

⭐ IK05 — an impact rating, which is rare here

⭐ The sheet publishes IK05, and only 23 products in this catalogue publish an IK figure at all. ⭐⭐ IK RATES RESISTANCE TO IMPACT: IK05 is about a 0.7-joule blow, which is a knock rather than a strike. ⭐ On a ceiling downlight it mostly matters during construction and when something long is carried through a room — a ladder, a length of timber, a curtain rail. ⭐ It is a mild rating and worth having; ⚠ it is not a vandal-resistance figure, and it is not a substitute for keeping a fitting out of harm's way.

⭐ IP44, 60° and a 35,000-hour life

• ⭐ IP44 covers splashing water from any direction — enough for a bathroom outside the direct wet zones, ⛔ not for a shower enclosure. ⚠ Confirm the zone with your electrician.
• ⭐ THE 60° BEAM IS NARROWER THAN A GENERAL-PURPOSE DOWNLIGHT'S 90–120°, ⭐ which is part of the anti-glare design — less light escapes sideways. ⚠ Plan the spacing tighter: roughly the ceiling height apart on a 2.4 m ceiling rather than 1.5× it.
• ⭐ 35,000 hrs is lower than the 50,000 most fittings here claim. ⭐ At three hours a day that is over thirty years, so it is not a practical constraint — and a realistic figure is more useful than an optimistic one.
• ⭐ DIMMABLE WITH SUITABLE DIMMERS, on an integrated driver with flex and plug. ⚠ “Suitable” is the operative word — a mismatched dimmer gives flicker and buzz rather than a clean failure.

✅ What is published

Where it works

• ⭐⭐ Replacing failed downlights — ⭐ Ø90–100 mm existing holes.
• ⭐ Bedrooms and lounges — ⭐ the deepest, lowest-glare option.
• ⭐ Dark or moody ceilings — ⭐ black on black disappears.
• ⚠ Not in a shallow void — ⭐ 56 mm plus driver; take the SLEEK.
• ⛔ Not in a shower enclosure — ⚠ IP44.

Specifying it

Recessed LED downlight, deep anti-glare fascia. 8 W at 240 V AC. 800/900/850 lm at 3000/4000/5700 K switchable. CRI ≥80, 60° beam. Cutout Ø90–100 mm, fitting depth 56 mm. IP44, IK05. Clear lens, dimmable driver with flex and plug. 35,000 hrs. Black fascia on black inner. Five-year residential warranty per the sheet. ⛔⛔ ITS CUTOUT IS Ø90–100 mm, AND WE MEASURED THAT NO PRODUCT RECORD IN THIS CATALOGUE PUBLISHES A CUTOUT AT ALL — 0 of 843, against 87 datasheets that give one. On a recessed downlight the cutout is the figure that matters most, because it is the only dimension that cannot be corrected once cut. ⭐⭐ AND THE RANGE IS THE POINT OF A "SWAP": it drops into an existing hole anywhere between 90 and 100 mm, which turns replacing a failed downlight from a repair into a swap — no re-cutting, no patching, no repainting. Measure the existing hole before ordering.
