The Domus Maxi 40 is a 1.7m suspended LED linear pendant 34W, 3400lm, 4000K atCRI90, dimmable, in a white body with a high diffuser.

Made to order, and no lead time is published

Domus asks you to call and confirm it and an institutional programmewith a handover date should settle that at the start. We will.

For a healthcare, education or civic specification clause by clause

• CRI90 is the clause it clears most comfortably. Clinical and educationalspecifications commonly set CRI80 as the minimum, and skin-tone assessment benefits frommore so this exceeds the requirement rather than meeting it.
• UGR is the gap that can actually block a submission. In a ward or aclassroom people look up a patient on their back, a child at a whiteboard and a glare limit is the clause most likely to be named explicitly.
• Ask us for UGR and the lifespan before submission. They are one enquiry,and the other seven clauses are already in hand.

What you can do about glare while the figure is outstanding

• Specify the PRISMATIC finish. It refracts shallow-angle light backtowards the vertical rather than scattering it, which is the component that reaches anupward-facing eye.
• Do not use CLEAR anywhere people look up.
• And note the diffuser TYPE is not the lever flat, high and low allpublish 3400lm and the same 120 beam, so the type is an appearance andmounting-depth choice. The finish is what changes the optics.

Where IP20 draws the boundary

Wards, classrooms, consulting rooms, corridors, libraries and offices are dryinteriors fine. Ensuite bathrooms, sluice rooms, hydrotherapy areas and covered walkwaysare not. For those, the Domus IMPACT range is IP66 and IK10.

The published specification

Where it works

• Consulting and treatment rooms CRI90 for skin tone.
• Classrooms, libraries and staff rooms.
• Corridors, reception and admin.
• Wards subject to the UGR clause.
• Not ensuites, sluice rooms or covered walkways IP20.

Specifying it

1.7m suspended LED linear pendant. 3400lm, 34W (100lm/W), 4000K,CRI90. 120 down-only. IP20. 1700mm. 3m drop. PLEX-COB-20W strip, integral dimmable driver,DALI and emergency on request. White body, high diffuser. 3-year replacement warranty. Order codeMAXI-40-1.7M-HD-W-4K. SKUs 3027530278. 240V. SEVEN OF THE NINE USUAL CLAUSES ARE SUPPORTED illuminance, colour temperature, CRI90, IPrating, connected load, emergency and DALI. CRI90 EXCEEDS the CRI80 floor most clinical specificationsset. The two gaps are a UGR glare figure and the rated lifespan, and UGR is the one most likely to benamed explicitly. Ask us for both before submission.

Questions

Can this be specified for a hospital or a school?

For most of the specification, yes. Seven of the nine clauses these projects usually name are supported: maintained illuminance from the published 3400 lumens, colour temperature at 4000K, colour rendering at CRI90, ingress protection at IP20, connected load, emergency lighting on request and DALI control on request. The two gaps are a UGR glare figure and the rated lifespan.

Is CRI90 enough for clinical work?

It exceeds the usual requirement. Clinical and educational specifications commonly set CRI80 as the minimum, and skin-tone assessment benefits from more than that so CRI90 clears the bar comfortably rather than just meeting it. Most commercial linear lighting settles for CRI 80 or better, including the Domus MAX-50 profile range, so this is a genuine advantage in a clinical setting.

What about the glare requirement?

That is the gap that can actually block a submission. UGR is not published on any Domus linear listing, and it matters in a ward or a classroom because people look up a patient on their back, a child at a whiteboard. If your specification names a UGR limit, ask us before submission; it is one enquiry to Domus, and the other seven clauses are already in hand.

What can I do about glare in the meantime?

Specify the prismatic finish. It refracts shallow-angle light back towards the vertical rather than scattering it, which is the component that reaches an upward-facing eye. Do not use clear anywhere people look up. And note that the diffuser type is not the lever flat, high and low all publish 3400 lumens and the same 120 degree beam, so the type is an appearance and mounting-depth choice while the finish is what changes the optics.

Where does IP20 stop me?

Wards, classrooms, consulting rooms, corridors, libraries and offices are all dry interiors and are fine. Ensuite bathrooms, sluice rooms, hydrotherapy areas and covered walkways are not. For those, ask us about the Domus IMPACT range, which is IP66 and IK10 and publishes both figures.

What is the rated lifespan?

Not published for this range, which is the second gap. On an institutional project that matters for the maintenance schedule rather than the specification itself. The Domus MAX-50 profile range publishes 50,000 hours as a comparable, but we will not assume the Maxi 40 matches it ask us and we will get the figure.

Can the emergency function replace a separate emergency fitting?

That is the point of it with the emergency option the pendant forms part of the escape-lighting provision instead of needing a separate luminaire alongside. It is ordered with the fitting rather than added later, and what is not published is the duration or whether it is maintained or non-maintained. On a compliance job both are specification items; ask us and we will get them in writing.
