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.

It is the answer whenever the recessed version will not fit

• The recessed MAX-50 needs 75mm of depth above the ceiling line. Very often that depth is not there: a shallow batten void, a concrete soffit with adirect-fixed lining, a run crossing a duct or a beam.
• This version does the same job below the ceiling. Same 17.3W/m, same2,466lm/m, same 21 variants, same profile.
• So the choice between them is a ceiling question, not a lighting one and itis worth checking the plenum before you specify either.
• What you give up is the flush line. A surface profile reads as an appliedobject; a recessed one reads as part of the ceiling. On a considered architectural ceiling thatdifference is the whole point; in a corridor or a plant room it is immaterial.
• It also fixes to a concrete soffit directly, which a recessed profile cannot do atall.

It is the only MAX listing that records its own output

• This record carries lumens = 2466lm | 2600lm. Its eight MAXsiblings leave that figure to the datasheet.
• Worth crediting, because output per metre is the figure a lighting calculation actually runson a designer working from product records rather than PDFs can use this one and cannot usethe others.
• Its power field rounds 17.3W to 17W a trivial difference on onemetre, but 3W over a 10-metre run.
• 2,466lm/m at 3000K and 2,600 at 4000K works out at about 150lm/W high, where most of this catalogue sits between 60 and 100.

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

• 21 variants including DALI, 010V and TUNABLE/DALI, on a listingrecording 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 profile listings.
• On a surface run, this is at least recoverable: retro-fitting DALI still meansreplacing the luminaire, but a surface profile can be taken down without opening aceiling which is a genuine advantage over the recessed version.
• TUNABLE/DALI shifts colour temperature from the controller. DALI only, in noproduct field.

Specifying it

• Profile 50mm wide 75mm high, all of it below theceiling. Which is worth picturing: a 75mm-deep line across a 2.4m ceiling isa visible architectural element, not a discreet one.
• Extruded 6063 aluminium, clear anodised, black or white. Flat high-outputopal-frost PMMA diffuser. Osram LED boards.
• CRI 80. 120. 50,000hrs. IP20 indoor and dry.
• On request: high-output LED boards and integrated emergency. Neither is avariant.

Where it works

• Anywhere the recessed version fails on ceiling depth.
• Concrete soffits where recessing is not possible at all.
• Corridors, offices and retail, in continuous surface lines.
• Retrofits into finished ceilings.
• Not where a flush architectural line is the point use the recessedversion.

Questions

When should I choose surface over recessed?

Whenever the ceiling depth is not there the recessed MAX-50 needs 75mm above the ceiling line, and very often it is not available: a shallow batten void, a concrete soffit with a direct-fixed lining, a run crossing a duct or beam. This version does the same job below the ceiling with the same 17.3W per metre, the same 2,466 lumens per metre and the same 21 variants. So the choice is a ceiling question, not a lighting one. It also fixes to a concrete soffit directly, which a recessed profile cannot do at all.

What do I give up by surface mounting?

The flush line. A surface profile reads as an applied object; a recessed one reads as part of the ceiling. On a considered architectural ceiling that difference is the whole point, and in a corridor or plant room it is immaterial. Worth picturing the scale: a 75mm-deep line across a 2.4m ceiling is a visible architectural element rather than a discreet one, so it wants to be deliberate aligned with something, or running the full length.

How much light does it give?

2,466 lumens per metre at 3000K and 2,600 at 4000K, which works out at about 150 lumens per watt high, where most fittings in this catalogue sit between 60 and 100. Worth noting that this is the only MAX listing that records its lumen output in a product field rather than leaving it to the datasheet. That is genuinely useful: output per metre is the figure a lighting calculation runs on, and a designer working from records rather than PDFs can use this one and cannot use its eight siblings.

Is it 17W or 17.3W per metre?

17.3W the datasheet figure, and the one every other MAX-50 sheet gives. This listing’s power field rounds it to 17W, which is trivial on a single metre but 3W over a 10-metre run. Use 17.3W per metre for circuit and driver calculations. Worth knowing that the recessed MAX-50 listing records 21W, which is a much larger discrepancy and disagrees with its own datasheet.

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 a surface run this is at least recoverable: retro-fitting DALI still means replacing the luminaire, but a surface profile can be taken down without opening a ceiling, which is a real advantage over the recessed version.

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. It is DALI only, so a 010V system cannot have it, and it appears in no product field at all. On a surface-mounted run it is easier to change your mind later than on a recessed one, but it is still a luminaire replacement rather than a module swap.

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 in the first place.
