The Domus Maxi 40 is a 1.2m suspended LED linear pendant 24W, 2400lm, 4000K atCRI90, dimmable, in a black body with a high diffuser.

Made to order, and no lead time is published

Domus asks you to call and confirm it. We will.

A 120 beam, and what it means for spacing a row

• 120 is a wide beam a general wash rather than an accent.The light spreads to roughly 3.5 times the mounting height in width, so apendant 1m above a bench throws a pool about 3.5m across.
• Which gives you a usable spacing rule for a row. To keep the light evenbetween fittings, space them at roughly the mounting height above the working plane, up to about 1.5times it so at 1m above a bench, fittings on 11.5m centresgive a continuous level, and 2m centres will scallop.
• The wide beam is why these work in a row rather than only over discrete tables. A narrow-beam fitting at the same spacing would leave dark bands between the pools.
• These are planning proportions, not a lighting design. With 2400lmand a 120 beam published, a real calculation is now possible tell us the roomand we will do it.

“Down only” is the other half of the beam figure

• Domus records the sub-category as DOWN ONLY. All 2400lm goesdownward; none is thrown up onto the ceiling.
• That is efficient every lumen lands where the work is and it makes the ceiling read darker than an up-down fitting would.
• Against a black or exposed ceiling that is the intent. Against whiteplasterboard in a low room, an all-downward fitting can make the space feel more enclosed, which is worth knowing before you specify a row of them into a domestic-scaleinterior.

The published specification

The 120 figure is recorded identically across the flat, high and low diffusers, and so is the lumen output which is consistent, and means the diffusertype is not changing the distribution in any way Domus publishes.

Where it works

• Rows over benching on 11.5m centres at 1m mounting.
• Exposed-services and dark ceilings.
• Workstations and studio benches at 4000K.
• Not in a low white-ceilinged room if the space should feel open.
• Not anywhere damp IP20.

Specifying it

1.2m suspended LED linear pendant. 2400lm, 24W, 4000K, CRI90.120 beam, down only. IP20. 1200mm. 3m drop. PLEX-COB-20W strip, integraldimmable driver, DALI and emergency on request. Black body, high diffuser. 3-year replacement warranty.Order code MAXI-40-1.2M-HD-B-4K. SKUs 3018030183. 240V. 120 IS A WIDE BEAM light spreads to roughly 3.5 the mounting height, so a pendant 1mabove a bench throws a pool about 3.5m across. For an even row, space them at roughly the mountingheight up to about 1.5 it; 2m centres at 1m mounting will scallop. Down only means theceiling stays dark the intent under exposed structure, worth checking in a low white-ceilingedroom.

Questions

What does a 120 degree beam mean in practice?

It is a wide beam a general wash rather than an accent. The light spreads to roughly 3.5 times the mounting height in width, so a pendant 1m above a bench throws a pool about 3.5m across. That width is why these work in a row rather than only over discrete tables: a narrow-beam fitting at the same spacing would leave dark bands between the pools.

How far apart should I space a row?

To keep the light even between fittings, space them at roughly the mounting height above the working plane, up to about 1.5 times it. So at 1m above a bench, fittings on 1 to 1.5m centres give a continuous level, while 2m centres will scallop. Those are planning proportions rather than a lighting design but with 2400 lumens and a 120 degree beam both published, a real calculation is now possible. Tell us the room and we will do it.

What does “down only” change?

All 2400 lumens go downward and none is thrown up onto the ceiling. That is efficient every lumen lands where the work is and it makes the ceiling read darker than an up-down fitting would. Against a black or exposed ceiling that is exactly the intent. Against white plasterboard in a low room, an all-downward fitting can make the space feel more enclosed, which is worth knowing before you specify a row into a domestic-scale interior.

Does the diffuser type change the distribution?

Not in any way Domus publishes. The 120 degree figure is recorded identically across the flat, high and low diffusers, and so is the lumen output. That consistency is worth noting: whatever the diffuser type changes, neither the total output nor the published beam angle is affected by it.

How much light does it give?

2400 lumens at 2000 lumens per metre, or 100 lumens per watt from 24W that is the 4000K figure. The 3000K version of the same fitting gives 2160 lumens. Combined with the beam angle, that is enough to plan a row properly rather than guess at it.

Why the black body at 4000K?

It is the exposed-services and studio combination a black body joins bare or dark structure instead of fighting it, and 4000K keeps the space reading as a workplace rather than a bar. Against white plasterboard the same fitting becomes a deliberate graphic statement instead.

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.
