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

Two of its four finishes share one product code and this is the awkward pairing

• Prismatic and frosted are hard to tell apart on delivery both present as adiffused white face but they do genuinely different optical jobs.
• PRISMATIC refracts shallow-angle light back towards the vertical, which iswhat stops the fitting reflecting in a monitor. FROSTED scatters instead softer to look at, and it still emits that shallow-angle component.
• So a wrong delivery here does not announce itself. It surfaces monthslater as glare on screens which is why this pairing matters more than thefrosted-and-black one elsewhere in the range.
• Tell us the finish in words and we will confirm the code with Domus before the order goesin. 49 of the 53 listings run their SKUs consecutively with no repeats, so thisis a genuine break rather than a convention.

And white + 4000 K is the open-plan office specification

A white body recedes into a plasterboard or grid ceiling, 4000K isthe working neutral, and 3400lm at 100lm/W over a two-person desk bank iswell matched. Which makes it a listing likely to be ordered in quantity and therefore one where getting the finish code right once, at the start, matters most.

The published specification

Made to order, and no lead time is published

Domus asks you to call and confirm it and we will confirm your finishcode in the same call.

Where it works

• Two-person desk banks at 1.7m.
• Open-plan floors with white or grid ceilings.
• Meeting rooms and reception.
• Not ordered on the dropdown alone two finishes share a code.
• Not anywhere damp IP20.

Specifying it

White body, flat diffuser. 3-year replacement warranty. Order codeMAXI-40-1.7M-FD-W-4K. SKUs 3024530248. 240V. “PRISMATIC” AND “FROSTED” BOTH RESOLVE TO 30245, and 30246 is absent. These two are hard totell apart on delivery but do different optical jobs prismatic REDIRECTS shallow-angle light wherefrosted only scatters it. So a wrong delivery surfaces months later as glare on screens rather thanimmediately. Tell us the finish in words.

Questions

Why do two finishes have the same product code?

“Prismatic” and “Frosted” both resolve to SKU 30245, and 30246 the code the sequence requires is absent. It is a genuine break rather than a convention: 49 of the 53 Maxi 40 listings run their four variant SKUs consecutively with no repeats, and seven Domus products across four families carry the same fault.

Would I notice if the wrong one arrived?

Probably not, and that is what makes this pairing the awkward one. Prismatic and frosted both present as a diffused white face, so they are hard to tell apart on delivery but they do genuinely different optical jobs. A wrong delivery does not announce itself; it surfaces months later as glare on screens. Elsewhere in the range the same fault pairs frosted with black, which are visibly unalike, so the error is caught immediately.

What is the actual difference between them?

Prismatic refracts shallow-angle light back towards the vertical, which is what stops the fitting reflecting in a monitor the reflection you see is shallow-angle light from a fitting behind you. Frosted scatters instead: softer to look at, and it still emits that shallow-angle component. Over desks, prismatic is the one to use.

How do I make sure I get the right one?

Tell us the finish in words and we will confirm the code with Domus before the order goes in. It takes one line on an email and it removes the risk entirely which matters more here than elsewhere, because this listing is white plus 4000K, the standard open-plan office specification, and therefore one likely to be ordered in quantity.

How much light does it give?

3400 lumens at 2000 lumens per metre, or 100 lumens per watt from 34W, at 4000K and CRI90. Over a two-person desk bank at 1.7m that is well matched. Across a floor, roughly four to five per 20 square metres gives a 320-lux general-office level at ordinary factors.

Is there a glare rating?

No UGR is not published on this or any Domus linear listing, which is the gap most likely to matter in an office specification. Specify the prismatic finish regardless, since it is the right optic whether or not the number is available. If your specification names a UGR limit, ask us before committing.

Can I use it in a damp space?

No IP20, dry interior only. For bathrooms, covered outdoor areas, commercial kitchens or unsealed bays, ask us about the Domus IMPACT range at IP66 and IK10.
