The Domus MAX-75 Recessed is an aluminium profile luminaire recessed into a ceiling, soldby the metre 17.3W per metre from a 75mm-wideaperture, with 3000K, 4000K or tunable white and DALI and010V options. 3-year warranty.

Its own sources disagree on the depth and that decides whether it fits

• A 20mm disagreement, on a recessed product, on the figure that decides whether it fitsthe void.
• The two pendant listings agree at 95mm; the two profile listings disagree withthemselves. So the weight of evidence favours 95mm but weare not going to settle a ceiling cut-out on a majority vote.
• Plan on 95mm and confirm with us before you commit. If your void isbetween 75 and 95mm, this is the question that decides the job, and it takes one call toDomus to answer.
• If the depth is genuinely not there, the MAX-75 Surface Mounted version does the same jobbelow the ceiling.

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

• Same 17.3W/m and same 2,466lm/m as the MAX-50 from a75mm aperture instead of 50mm.
• The same light over 50% more emitting area is roughly a third less surfacebrightness. Nothing in the catalogue says so, and a buyer would reasonably assumethe wider profile is brighter.
• Recessed, this matters in corridors and open offices with low ceilings, where anarrow bright line in the field of view is what people notice and complain about.
• It also means a 75mm-wide cut-out rather than 50 more ceiling toopen, and a wider band of setting-out to get straight.

Two more gaps in this listing’s record

• It records no power figure at all, where its siblings record 17, 17.3 or (wrongly)21W. The datasheet says 17.3W/m and we have published that.
• Its datasheet has a parse fault: the 4000K lumen figure has landed in the LEDtype field, so Osram LED Boards does not appear on this one sheet. Every other MAX sheet names them, and the prose on this sheet confirms it.
• Which is worth stating rather than quietly correcting: it is the same light engine,and the gap is in the document rather than the product.

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. On a recessed run, choose the control before the ceilingcloses retro-fitting means replacing a luminaire that is in the ceiling.

Specifying it

• 2,466lm/m at 3000K, 2,600lm/m at 4000K. About150lm/W.
• Extruded 6063 aluminium, clear anodised, black or white. Flat high-outputopal-frost PMMA diffuser.
• CRI 80. 120 a wash, not an accent. 50,000hrs.IP20.
• On request: high-output LED boards and integrated emergency. Neither is a variant and emergency is the one to settle before the ceiling closes.

Where it works

• Corridors and open offices with low ceilings where the low-glare apertureearns its place.
• Reception and retail, in flush continuous lines.
• Not in a void whose depth you have not confirmed the sources disagree by20mm.
• Not where a 75mm cut-out is more ceiling than you want to open.
• IP20 indoor and dry only.

Questions

How deep is the profile 75mm or 95mm?

Its own sources disagree, and on a recessed product that is the figure that decides whether it fits. The datasheet says the profile is 75 75mm; the product record says 95mm high. Measured across the four MAX-75 listings, the two pendants agree at 95mm and the two profile listings disagree with themselves. So the weight of evidence favours 95mm but we are not going to settle a ceiling cut-out on a majority vote. Plan on 95mm and confirm with us before you commit. If your void is between 75 and 95mm, that one call to Domus decides the job.

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

No. Same 17.3W per metre, same 2,466 lumens per metre the difference is the aperture, 75mm against 50mm. The same light over 50% more emitting area is roughly a third less surface brightness, so the MAX-75 is the gentler product rather than the brighter one. Nothing in the catalogue says so, and a buyer would reasonably assume the opposite. Recessed, it earns its place in corridors and low-ceiling offices, where a narrow bright line in the field of view is what people notice and complain about.

What power should I use for calculations?

17.3W per metre, from the datasheet. This listing records no power figure at all, where its siblings record 17W, 17.3W or in the case of the MAX-50 recessed 21W, which disagrees with its own sheet. Over a 10-metre run 17.3W per metre is 173W, and that is the figure to size a circuit or a driver on.

Why does this sheet not mention Osram boards?

A parse fault in the document rather than a difference in the product. On this one datasheet the 4000K lumen figure has landed in the LED type field, so “Osram LED Boards” does not appear where it should. Every other MAX sheet names them and the prose on this sheet confirms it. It is the same light engine as the rest of the range worth stating rather than quietly correcting, because the gap is in the paperwork and you should know that is what it is.

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 the same, so filtering a catalogue on dimmable hides all of them. On a recessed run choose the control before the ceiling closes: retro-fitting means replacing a luminaire that is in the ceiling, which is a very different job from swapping a surface fitting.

Is the 120 beam right for a corridor?

Yes a 120 beam from a recessed line washes floor and walls broadly rather than accenting, which is what a corridor or open office wants. Combined with the wider MAX-75 aperture it gives a notably comfortable result at low mounting heights. What it will not do is create contrast: for a display run or anywhere you want things picked out, this is the wrong distribution.

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. On a recessed run this is the option to settle before the ceiling closes retrofitting afterwards means either opening the ceiling again or fitting a separate emergency luminaire alongside, which breaks a continuous flush line and rather defeats the point.
