The Domus Maxi 40 is a 2.4m suspended LED linear pendant 48W, 4320lm, 3000K 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. We will.

Setting out a row the gap, the alignment and the batch

• THE GAP. A gap of about half a fitting length or more reads as adeliberate rhythm; a small gap reads as a continuous run that failed to join which is the uncomfortable case, because it looks like a mistake rather than achoice.
• And there is a lighting constraint as well as a visual one. The 120 beamspreads to roughly 3.5 times the mounting height, so at 1m above the workingplane each fitting covers about 3.5m across which means gaps up to about1m keep the level even between 2.4m fittings. Wider than that and you willsee a scallop between them.
• THE ALIGNMENT. Two suspension points per fitting means four fixings perpair, and any error is visible down the whole room because the fittings are long andparallel. The spacing is not published ask before setting out.
• THE BATCH. Made to order and powder-coated, so a second order is notguaranteed to match and on a white body side by side that shows more readilythan on a dark one. Order the run together.

A row, in numbers

Both columns calculate directly load from 20.0W/m and output from thepublished 4320lm. Turning lumens into lux still needs the room; tell us and wewill do it.

And add a spare

On a run of eight or more, order one extra from the same batch. This is anintegrated LED with no lamp, the rated lifespan is not published, and a replacement is made to order on an unknown clock. A spare removes all threeat once.

The published specification

Where it works

• Rows over benching and long counters.
• Corridors of tables in hospitality and education.
• White and plasterboard ceilings.
• Runs ordered in one go one batch, one finish.
• Not set out until we have the suspension spacing.

Specifying it

2.4m suspended LED linear pendant. 4320lm, 48W (90lm/W), 3000K,CRI90. 120 down-only. IP20. 2400mm. 3m drop. PLEX-COB-20W strip, integral dimmable driver,DALI and emergency on request. White body, high diffuser. 3-year replacement warranty. Order codeMAXI-40-2.4M-HD-W-3K. SKUs 3035030353. 240V. THE GAP IS NOW A CALCULATION, NOT A GUESS the 120 beam spreads to roughly 3.5 the mountingheight, so at 1m above the working plane each fitting covers about 3.5m and gaps up to about1m keep the level even. Wider and you will see a scallop. Visually, half a fitting length or morereads as rhythm; a small gap reads as a failed run.

Questions

How far apart should a row of these be?

There are two constraints and they mostly agree. Visually, a gap of about half a fitting length or more reads as a deliberate rhythm, while a small gap reads as a continuous run that failed to join which looks like a mistake rather than a choice. On the lighting side, the 120 degree beam spreads to roughly 3.5 times the mounting height, so at 1m above the working plane each fitting covers about 3.5m across, and gaps up to about 1m keep the level even between 2.4m fittings. Wider than that and you will see a scallop.

What else makes a row look wrong?

Alignment and batch. Two suspension points per fitting means four fixings per pair, and any error is visible down the whole room because the fittings are long and parallel and the point spacing is not published, so ask before setting out. And these are made to order and powder-coated, so a second order is not guaranteed to match the first, which on a white body side by side shows more readily than on a dark one.

What load and output will a row give?

Both calculate directly: load from 20.0 watts per metre and output from the published 4320 lumens. Three fittings is 144W and 12,960 lumens, five is 240W and 21,600 lumens, eight is 384W and 34,560 lumens. Turning lumens into lux still needs the room’s surfaces and geometry tell us and we will do it.

Should I order a spare?

On a run of eight or more, yes. This is an integrated LED with no lamp, the rated lifespan is not published, and a replacement is made to order on an unknown clock. One extra fitting from the same batch removes all three problems at once, and on a white powder coat it also guarantees the finish matches.

Should I order the run in stages?

No. A later order starts its own unknown lead-time clock and a powder-coat batch is not guaranteed to match which on a row of white fittings seen side by side is exactly where it shows. Order one finish, one colour temperature, one batch.

How much light does each give?

4320 lumens at 1800 lumens per metre, or 90 lumens per watt from 48W, at 3000K and CRI90. The 4000K version gives 4800 lumens for the same power, about 11% more, if the space suits neutral light.

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.
