The Domus PIPE-60 is a 60mm linear pendant 21W or 31W, 1.2m or 1.7m, tri-colour,full wrap-around opal diffuser, in aluminium, black or white.

One of its published lumen figures is missing a digit

• The record lists four outputs: 658, 2349, 1797 and 2546lm. One ofthose is not like the others.
• 658lm from 21W is 31lumens per watt. No LED pendantproduces that it is roughly what a halogen lamp achieves. That was the tell.
• The supplier’s own description reads: Lumen Output:1658lm/1797lm 2349lm/2546lm. The figure is 1658, not658. A leading 1 has been dropped somewhere between the description and the field.
• Restored, the whole set makes sense:

Every value now sits between 76 and 86lumens per watt, which is exactly right for adiffused linear pendant. Use 1658lm as the lower figure, not 658. The difference is a factor of two and a half in a lighting calculation.

Osram boards and a remote driver what each means for you

• Domus names the LED source: Osram boards. Very few fittings in thiscatalogue name their emitter at all, and it matters for colour consistency betweenfittings and over time a named emitter is a binned emitter.
• Supplied with remote driver which needs to be mounted separately. The driver is INCLUDED but does not live in the pendant so theceiling needs somewhere accessible to put it, decided before the ceiling closes.
• A remote driver is why a 60mm tube can be this slim, and it meansthe part most likely to fail is the part you can reach. That is a real advantage,provided the location is planned.

Nine variants: three finishes three colour temperatures

Aluminium, black or white; 3000, 4000 or 5000K. The colourtemperature is fixed at order this listing is not switchable, so choose it now.Over a dining table 3000K; over a bench or a workspace 4000K; in a retail or commercial fitout4000 or 5000K. It is also non-dimmable, so the level cannot beadjusted afterwards either.

Made to order, cut to length and custom lengths exist

Allow up to 10 business days. 1.2m and 1.7m are standard, andDomus offers CUSTOM LENGTHS on request which is unusual and worth knowing if abench or table is an awkward size. Ask us.

The published specification

Where it works

• Dining tables and islands 1.2m or 1.7m.
• Retail and commercial fitouts.
• Awkward table sizes custom lengths on request.
• Not on a dimmer non-dimmable.
• Not calculated from 658lm the figure is 1658.

Specifying it

60mm linear LED pendant. 21W at 1.2m or 31W at 1.7m, 240V AC.16581797lm / 23492546lm. 3000, 4000 or 5000K, fixed at order. 120 beam.IP20. Non-dimmable. Full wrap-around opal diffuser. Osram LED boards. Remote driver included, mountedseparately. Anodised aluminium, black or white. Custom lengths on request. 5-year replacementwarranty. ONE PUBLISHED LUMEN FIGURE IS MISSING A DIGIT the record says 658lm where the description says1658lm. 658lm from 21W is 31lm/W, which no LED pendant produces; restored to 1658 the whole setfalls between 76 and 86lm/W, exactly right for a diffused linear pendant. THE DIFFERENCE IS AFACTOR OF TWO AND A HALF in a lighting calculation.

Questions

How much light does it give?

1658 to 1797 lumens at 1.2m and 21W, or 2349 to 2546 lumens at 1.7m and 31W. Note that one published figure reads 658lm rather than 1658lm a dropped leading digit. 658lm from 21W would be 31 lumens per watt, which no LED pendant produces; restored to 1658, every value in the set sits between 76 and 86 lumens per watt, which is exactly right for a diffused linear pendant.

Why does that matter?

Because it is a factor of two and a half in a lighting calculation. If you sized a room on 658 lumens you would specify roughly two and a half times as many fittings as you need. The supplier’s own description carries the correct figure it is the structured record that lost the digit.

Where does the driver go?

Somewhere you can reach it. The driver is included but remote Domus says it “needs to be mounted separately” so the ceiling needs an accessible location decided before it closes. That is why a 60mm tube can be this slim, and it has a real advantage: the part most likely to fail is the part you can get to.

What are Osram boards, and why mention them?

They are the LED source, and very few fittings in this catalogue name their emitter at all. It matters for colour consistency between one fitting and the next, and over the life of the installation because a named emitter is a binned emitter, selected to a tolerance rather than taken as it comes.

Can I change the colour temperature later?

No. This listing fixes it at order you choose 3000K, 4000K or 5000K when you buy, and there is no switch. Over a dining table take 3000K; over a bench or workspace 4000K; in a retail or commercial fitout 4000 or 5000K. It is also non-dimmable, so the level cannot be adjusted afterwards either.

What lengths are available?

1.2m and 1.7m as standard, and Domus offers custom lengths on request which is unusual and genuinely useful if a bench or table is an awkward size. It is made to order in any case, so a custom length does not add a separate process. Ask us.

What is the warranty?

Five years, replacement which is longer than most of this catalogue, where three years is the norm and some exterior ranges carry twelve months. Combined with the named Osram emitter and the accessible remote driver, it suggests a fitting intended for commercial service life.
