The Domus MAX-75 Surface Mounted is an aluminium profile luminaire fixed to the ceiling,sold by the metre 17.3W per metre from a 75mm-wideaperture, with 3000K, 4000K or tunable white and DALI and010V options. 3-year warranty.

Here the depth disagreement does not stop the job but it changes the look

• Its datasheet says the profile is 75 75mm; its record says 95mm high. Both MAX-75 pendant listings agree at 95mm.
• On a SURFACE fitting that is a visual question rather than a fit one nothing has to be cut, and nothing will fail to go in. On the recessed siblingthe same 20mm can stop a job.
• But 75 or 95mm is a real difference in how it reads. Picture it: a95mm-deep line hanging below a 2.4m ceiling is close to a hand’s width of aluminium inview. That is an architectural element, not a discreet one.
• If the visual weight matters a low ceiling, a small room, a run at the edge of asight line ask us to confirm the section before you commit. If it does not, orderwith confidence.

The MAX-75 is the low-glare choice, not the brighter one

• The same light over 50% more emitting area. Nothing in the catalogue saysso, and the wider profile is easily assumed to be the brighter one.
• Surface mounted, this is most useful under low ceilings a surfacefitting is closer to the eye than a recessed one by its whole depth, so luminance matters more, notless.
• And it is the wider, deeper object of the two. Lower glare, morepresence that is the trade.

It fixes where a recessed profile cannot go at all

• Concrete soffits, shallow voids, direct-fixed linings, finished ceilings.Anywhere the 95mm of depth simply is not available above the line.
• And retrofits a surface run goes into a completed building without openinganything.
• It is also the easier one to live with. Retro-fitting DALI means replacingthe luminaire, and a surface profile comes down without a plasterer.

It records “not dimmable” and sells DALI, 0-10 V and tunable white

21 variants including DALI, 010V and TUNABLE/DALI, on a listing recordingdimmable = No. The base product is non-dimmable and control is a variantchoice; a single yes/no field cannot say that, so filtering on dimmable hides all 9 MAXprofile listings. TUNABLE/DALI shifts colour temperature from the controller DALI only, and in no product field.

Specifying it

• 2,466lm/m at 3000K, 2,600lm/m at 4000K. About150lm/W high, where most of this catalogue sits between 60 and 100.
• Extruded 6063 aluminium, clear anodised, black or white. Flat high-outputopal-frost PMMA diffuser. Osram LED boards which matter more on a wideaperture, where board-to-board colour variation has more diffuser to show on.
• CRI 80. 120. 50,000hrs.IP20.
• Its power field records 17.3W matching the sheet, unlike the MAX-50recessed listing’s 21W.
• On request: high-output LED boards and integrated emergency. Neither is avariant.

Where it works

• Concrete soffits and shallow voids where recessing is impossible.
• Retrofits into finished ceilings.
• Low-ceiling offices and corridors where the wide low-glare aperture earnsits place.
• Not where visual weight matters and the section is unconfirmed askus.
• Not where a flush architectural line is the point use the recessedversion.

Questions

Does the 75mm/95mm disagreement matter here?

Not for fit on a surface fitting nothing has to be cut and nothing will fail to go in, which is very different from the recessed sibling where the same 20mm can stop a job. But it does change how it reads. Picture it: a 95mm-deep line hanging below a 2.4m ceiling is close to a hand’s width of aluminium in view, which is an architectural element rather than a discreet one. If visual weight matters a low ceiling, a small room, a run at the edge of a sight line ask us to confirm the section before committing. If it does not, order with confidence.

Is the MAX-75 brighter than the MAX-50?

No same 17.3W per metre and same 2,466 lumens per metre. The difference is the aperture: 75mm against 50mm, so the same light spreads over 50% more emitting area and the surface brightness is about a third lower. Nothing in the catalogue says so, and the wider profile is easily assumed to be the brighter one. Surface mounted this matters more rather than less, because a surface fitting is closer to the eye than a recessed one by its whole depth.

When should I choose surface over recessed?

Whenever the depth is not available above the ceiling line concrete soffits, shallow voids, direct-fixed linings, finished ceilings. It is also the retrofit answer, going into a completed building without opening anything. And it is easier to live with: retro-fitting DALI means replacing the luminaire either way, but a surface profile comes down without a plasterer.

Can I dim it?

On the DALI or 010V variants, yes. The listing records dimmable as No because a single yes/no field cannot express a variant axis nine MAX profile listings are in the same position, so filtering a catalogue on dimmable hides all of them. TUNABLE/DALI also exists, shifting colour temperature from the control system, and it appears in no product field at all. Choose the control before the finish.

What power should I use?

17.3W per metre and this listing records it correctly, matching its datasheet. Worth noting because the MAX-50 recessed listing records 21W, which disagrees with its own sheet and with every sibling in the range. Over a 10-metre run 17.3W per metre is 173W, and that is the figure to size a circuit or driver on.

Why do the Osram boards matter more on this one?

Because a wider aperture gives board-to-board colour variation more diffuser to show on. Banding along a linear run is the commonest visible fault in this kind of lighting, and a 75mm-wide opal face displays it more readily than a 50mm one. A specified light engine makes that less likely, and makes a replacement board years later more likely to match.

Can I get emergency in the run?

Not as a variant, but the datasheet lists integrated emergency and high-output LED boards as available on request. Raise it at quotation stage on a continuous surface line, adding a separate emergency fitting later breaks the line visually, which rather defeats the point of specifying a continuous profile.
