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.

The up-light is a full second board, not a token uplift

• Both figures double exactly, which is worth saying: the upward half is afull board at full output, not a decorative uplift.
• Which changes what it does to a room. An equal up-component washes theceiling, and a lit ceiling is what stops a suspended pendant reading as a bright object in a darkplane it is the difference between a room that feels lit and a table that feelsspotlit.
• It needs a ceiling worth lighting. Against a white plasterboard soffit ittransforms the space; against exposed dark services or a high void it lights nothing and doubles yourenergy.
• So the honest test: look up. If there is a clean surface within about1.5m, take the two-way. If not, the down-only version does the same job for half the power.

It is 15 mm deeper than every other MAX-50

• 90mm high against 75mm the only MAX-50 with a differentsection. Width stays 50mm.
• Fifteen millimetres is small until it is not. On a suspended pendant itmatters for sight lines across a table and for the visual weight of a long run; and ifyou are matching a two-way run to a down-only run in the same space, they will not sit flush.
• Check it before mixing types in one room.

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

• 21 variants including 3000K/DALI, 4000K/DALI, 3000K/0-10V,4000K/0-10V and TUNABLE/DALI on a listing recording dimmable =No.
• The base product is non-dimmable and control is a variant choice; a singleyes/no field cannot say that, so filtering on dimmable hides all 9 MAX profilelistings.
• On a two-way fitting dimming earns its keep twice over: the up-light iswhat you want to take down first in the evening, and on DALI the two halves are still oneaddressable luminaire rather than separately controllable.
• If you want the up and down halves controlled separately, tell us nothingin the record says whether that is possible.
• TUNABLE/DALI shifts colour temperature from the controller DALI only, andin no product field.

Specifying it

• Profile 50mm wide 90mm high. Extruded 6063 aluminium,clear anodised, black or white. Flat high-output opal-frost PMMA diffuser.
• CRI 80. 120. 50,000hrs. IP20 indoor and dry. Osram LED boards.
• About 150lm/W on each board high for this catalogue.
• Over a table, 750900mm above the surface; but a two-waypendant benefits from a little more height, because the up-light needs room to spread before itreaches the ceiling.
• On request: high-output LED boards and integrated emergency. Neither is avariant.

Where it works

• Open-plan offices with a clean white soffit where the up-light does themost.
• Boardrooms and meeting rooms, suspended over the table.
• Reception spaces where the ceiling is part of the architecture.
• Not under exposed dark services or a high void the down-only version doesthe same job for half the power.
• Not mixed flush with down-only runs it is 15mm deeper.

Questions

Is the up-light a real light or a token uplift?

A full second board at full output. The power doubles exactly 34.6W per metre against the down-only 17.3 and so does the output, at 2 2,466 lumens per metre. Both figures doubling exactly is what tells you it is a genuine second engine. That changes what it does to a room: an equal up-component washes the ceiling, and a lit ceiling is what stops a suspended pendant reading as a bright object in a dark plane. It is the difference between a room that feels lit and a table that feels spotlit.

When is the two-way version not worth it?

When there is no ceiling worth lighting. Against a clean white plasterboard soffit it transforms the space; under exposed dark services, a high void or a dark-painted ceiling it lights nothing and doubles your energy. The honest test is to look up: if there is a clean surface within about 1.5m of the fitting, take the two-way. If not, the down-only version does the same job on the table for half the power.

Will it sit flush with the down-only version?

No it is 90mm high against 75mm, the only MAX-50 with a different section, though the width stays at 50mm. Fifteen millimetres is small until it is not: on a suspended pendant it matters for sight lines across a table and for the visual weight of a long run, and if you are matching a two-way run to a down-only run in the same space they will not align. Check it before mixing types in one room.

Can I dim it?

On the DALI or 010V variants, yes and on a two-way fitting dimming earns its keep twice over, because the up-light is usually what you want to take down first in the evening. The listing records dimmable as No regardless, because a single yes/no field cannot express a variant axis; nine MAX profile listings are in the same position. One thing the record does not say is whether the up and down halves can be controlled separately on DALI they may be one addressable luminaire rather than two. Tell us if that matters and we will ask Domus.

What does TUNABLE/DALI add?

Colour temperature shifted from the control system rather than fixed at 3000K or 4000K for the life of the fitting warm in the evening, neutral during the day. On a two-way pendant that is particularly effective, because the ceiling wash carries the colour of the room more than the downward light does. 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 a two-way 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. Tell us the ceiling height and we will suggest a drop.

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 commercial job that conversation is worth having at quotation stage, because retrofitting emergency into a suspended linear run afterwards means installing a second product alongside it visible, awkward, and more expensive than specifying it once.
