This item is made to order

Up to 10 business days for production before it ships which is what lets it becut to your run and finished in your colour.

It is both the highest-output and the lowest-glare linear in the MAX range

• Two things combine here that are usually a trade-off. The up-down doubles theoutput; the 75mm aperture spreads each half over 50% more area than a MAX-50.
• So it delivers the most light in the range from the lowest-luminance face which is exactly what a large open-plan office or a boardroom wants.
• Both figures double exactly against the MAX-75 Down, so the up-light is afull second board, not a token uplift.
• It needs a ceiling worth lighting. Against a clean white soffit the ceilingwash transforms the space; under exposed dark services it lights nothing and doubles your energy. The honest test is to look up.

Its web address claims the whole model name

• This listing sits at domus-max-75 the bare modelname.
• There are four MAX-75 products: recessed, surface mounted, down pendant and thisup-down pendant. All four are called MAX-75.
• So a URL that reads as a range page serves one specific variant and it is theone most people are not looking for, since the down-only pendant is the commoner choice.
• If you followed a link expecting the MAX-75 range and landed here, this is the UP-DOWNversion. Ask us for the other three.

Its datasheet prose describes the down-only version

The sheet text reads The MAX-75 Down suspension pendant on an up-down product. The specification table is correct itgives 34.6W/m and 2 2,466lm, which are the up-down figures but thedescriptive paragraph was copied from the down pendant. So read the table, not theprose.

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 an up-down fitting dimming earns its keep twice: the ceiling wash iswhat you want to take down first in the evening.
• Whether the up and down halves can be controlled separately is not stated anywhere. Ask us if that matters.
• TUNABLE/DALI shifts colour temperature from the controller DALI only, and inno product field. On an up-down pendant it is particularly effective, because the ceiling washcarries the colour of the room.

Specifying it

• Profile 75mm wide 95mm high. Extruded 6063 aluminium,clear anodised, black or white. Flat high-output opal-frost PMMA diffuser.Osram LED boards.
• CRI 80. 120. 50,000hrs. IP20 indoor and dry. About 150lm/W per board.
• Over a table, 750900mm above the surface and an up-downpendant benefits from a little more height, so the ceiling wash has room to spread.
• On request: high-output LED boards and integrated emergency. Neither is avariant.

Where it works

• Large open-plan offices with a clean soffit the range’s best combination ofoutput and comfort.
• Boardrooms and meeting rooms.
• Reception spaces where the ceiling is part of the architecture.
• Not under exposed dark services the MAX-75 Down does the same job for halfthe power.
• IP20 indoor and dry only.

Questions

Why is this the best MAX for a large office?

Because it combines two things that are usually a trade-off. The up-down configuration doubles the output to 2 2,466 lumens per metre, and the 75mm aperture spreads each half over 50% more area than a MAX-50 so it delivers the most light in the range from the lowest-luminance face. That is exactly what a large open-plan office or a boardroom wants: enough light, and a fitting you can sit under without squinting.

Is the up-light a real light?

A full second board. Both the power and the output double exactly against the MAX-75 Down 34.6 W/m against 17.3, and 2 2,466 lumens against 2,466 which is what tells you it is a genuine second engine rather than a token uplift. But it needs a ceiling worth lighting: against a clean white soffit the ceiling wash transforms the space, and under exposed dark services it lights nothing and doubles your energy. The honest test is to look up.

Why is its web address just “max-75”?

A cataloguing artefact worth knowing about. There are four MAX-75 products recessed, surface mounted, down pendant and this up-down pendant and all four are called MAX-75, but this listing sits at the bare model name. So a URL that reads as a range page serves one specific variant, and it is the one most people are not looking for, since the down-only pendant is the commoner choice. If you followed a link expecting the MAX-75 range and landed here, this is the up-down version; ask us for the other three.

Why does the datasheet say “Down”?

Because the descriptive paragraph was copied from the down-only pendant’s sheet. The specification table is correct it gives 34.6 W/m and 2 2,466 lumens, which are the up-down figures but the prose above it reads “The MAX-75 Down suspension pendant”. So read the table rather than the paragraph. The product is the up-down version.

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. On an up-down fitting dimming earns its keep twice, because the ceiling wash is what you want to take down first in the evening. One thing no source states is whether the up and down halves can be controlled separately; ask us if that matters.

What does TUNABLE/DALI add here?

Colour temperature shifted from the control system rather than fixed for the life of the fitting and on an up-down pendant it is particularly effective, because the ceiling wash carries the colour of the room more than the downward light does. Warm in the evening, neutral during the day, across the whole ceiling plane. It is DALI only, so a 010V system cannot have it, and it appears in no product field at all.

How high should I suspend it?

Over a table, 750 to 900mm above the surface is the usual range but an up-down pendant benefits from a little more height than a down-only one, because the up-light needs room to spread before it reaches the ceiling. Hung too close to the soffit, the ceiling wash becomes a bright stripe rather than an even glow, which rather defeats the point. Tell us the ceiling height and we will suggest a drop.
