The Domus GT-692 Vienna Large downward wall light is a wall-mountedexterior lantern 600mm high, 300mmprojection, 295mm wide, B22, 240V,IP23, in five colours.

Its IP23 is correct and it settles a question we raised two batches ago

• This product’s record says IP23 and its datasheet saysIP23. Consistent.
• TWO BATCHES AGO WE FLAGGED THE VIENNA 2LT AND 3LT POSTLIGHTS, whose sheets say IP23 whiletheir records say IP43, and recorded it cautiously as a sheet-versus-record conflict. We can now be much firmer.
• WE MEASURED THE WHOLE VIENNA FAMILY 25 PRODUCTS:
  • ALL 25 DATASHEETS SAY IP23.
  • 20 records say IP23.
  • EXACTLY 4 say IP43.
• SO IT IS NOT A SHEET-VERSUS-RECORD CONFLICT. IT IS FOUR PRODUCTS CONTRADICTING THEIR OWNFAMILY’S OTHER TWENTY AND ALL TWENTY-FIVE DATASHEETS. That is about as firm ascatalogue evidence gets.
• THE FOUR ARE THE NON-GT-NUMBERED ONES: the two wall brackets (15956,15962) and the two postlights (15968, 15974). Every GT-numbered VIENNA product recordsIP23.
• TREAT THE WHOLE FAMILY AS IP23. The difference matters: the solids digitseparates keeping out fingers from keeping out wires and insects, and on a garden lantern that decideswhether the fitting fills with insects the commonest complaint aboutlanterns.

IP23 is a real constraint, and it should shape where this goes

• IP2X keeps out objects over 12.5mm fingers, notinsects. IPX3 covers spraying water to 60 fromvertical. Not driving rain, not hosing, not sprinklers.
• ON A WALL FITTING THAT IS MORE CONSTRAINING THAN ON A POST, because a wall channels waterdown its face and rain arrives at the bracket from directly above.
• THE DOWNWARD ORIENTATION HELPS SUBSTANTIALLY. The lantern hangs beneaththe arm, so its own body sheds water away from the opening rather than collecting it which is whythis is the version to choose on an exposed elevation, ahead of the upwardGT-691.
• MOUNT IT UNDER AN EAVE, IN A PORCH, OR ON A WALL THAT IS NOT THE WEATHER SIDE IF YOUCAN. On a fully exposed elevation expect water to find it eventually, and check the sealsas part of any maintenance.

Downward-facing the considerate arrangement

• The lantern hangs beneath the arm and faces down. NOTHING GOES INTO THE SKY, the lantern body shades the source from anyone looking at the wallfrom a distance, and light lands on the ground where it is useful rather than on the wall above thefitting.
• ON A BOUNDARY WALL, A SHARED DRIVEWAY OR A DENSE STREET THAT MATTERS MORE THAN THEEFFECT. An upward lantern on a party wall is a complaint waiting to happen; a downwardone is not.
• THE COUNTER-ARGUMENT IS APPEARANCE the upward GT-691 is theclassic coach-lamp posture and reads as more traditional. Choose on the position ratherthan the picture.

300 mm projection, and “Large” is a separate range

• IT PROJECTS 300mm and hangs 600mm below the fixing. Enough to catch a door, a gate or someone carrying something past check the swing ofanything near it and the width of the path beneath.
• A USEFUL MOUNTING HEIGHT IS AROUND 2.02.2m to the fixing, putting the lantern bottomnear 1.41.6m. Mount them at a consistent height along a facade; uneven bracketsare conspicuous at night in a way they never are on a drawing.
• THE VIENNA LARGE IS A PARALLEL RANGE, NOT A SIZE OPTION. It uses bracketreference GT-691 and offers fewer arrangements than the standard VIENNA. Decide the largest arrangement a scheme needs first, then pick the family and do not mixthe two sizes on one property, because a large lantern beside a standard one reads as a mistake ratherthan a hierarchy.

B22, no lamp, and opal at a door

The lamp is not included. ON A WALL BRACKET THE LANTERN IS AT OR NEAREYE LEVEL FOR ANYONE APPROACHING THE DOOR, so a clear or filament lamp is a bright point directly in theirview. An opal B22 fills the lantern and reads as a glowing object. On the Large lantern that matters more, because a small bright source inside a big diffuser lookswrong. Warm rather than cool: at an entrance, cool white reads as institutional andunwelcoming.

Made to order

Allow up to 10 business days for production. Published, which is unusual inthis catalogue five colours in a made-to-order range means the finish is applied to yourorder.

What is published

Where it works

• Boundary and party walls nothing upward.
• Exposed elevations the downward body sheds water.
• Two-storey facades the Large lantern holds its own.
• Not near a door swing 300mm projects.
• Not mixed with standard VIENNA the sizes clash.

Specifying it

Exterior wall bracket, downward, LARGE lantern. 600mm high, 300mm projection,295mm wide. B22, lamp not included. 220240V. IP23. Aluminium. Five colours. Bracket referenceGT-691. Made to order, up to 10 business days. 1-year warranty. ITS IP23 IS CORRECT, AND IT SETTLES A QUESTION WE RAISED CAUTIOUSLY TWO BATCHES AGO. Weflagged the VIENNA 2LT and 3LT postlights for saying IP43 where their sheets say IP23, and recorded it as asheet-versus-record conflict. Measuring the whole family of 25 makes it firmer: ALL 25 DATASHEETS SAY IP23,20 RECORDS SAY IP23, AND EXACTLY 4 SAY IP43 the two wall brackets and the two postlights, every one ofthem non-GT-numbered. That is not a sheet-versus-record conflict; it is four products contradicting theirown family’s other twenty. TREAT THE WHOLE FAMILY AS IP23.

Questions

Is its IP rating reliable?

Yes its record says IP23 and its datasheet says IP23. That matters beyond this product, because it settles a question we raised cautiously two batches ago about the VIENNA postlights.

What was that question?

The VIENNA 2LT and 3LT postlights say IP43 in their records while their sheets say IP23, and we recorded it as a sheet-versus-record conflict. Measuring the whole family makes it much firmer: all 25 VIENNA datasheets say IP23, 20 records say IP23, and exactly 4 say IP43 the two wall brackets and the two postlights, every one of them non-GT-numbered. That is not a sheet-versus-record conflict; it is four products contradicting their own family’s other twenty.

So what should I assume?

Treat the whole VIENNA family as IP23. The difference matters: the solids digit separates keeping out fingers from keeping out wires and insects, and on a garden lantern that decides whether the fitting fills with insects the commonest complaint about lanterns.

Is IP23 enough on a wall?

It is a real constraint. IP2X keeps out objects over 12.5mm, which is fingers rather than insects, and IPX3 covers spraying water to 60 degrees from vertical not driving rain, hosing or sprinklers. On a wall that is more constraining than on a post, because a wall channels water down its face and rain arrives at the bracket from directly above.

Does the downward orientation help?

Substantially, and it is why this is the version to choose on an exposed elevation ahead of the upward GT-691. The lantern hangs beneath the arm so its own body sheds water away from the opening rather than collecting it. Still, mount it under an eave, in a porch, or on a wall that is not the weather side if you can.

Why downward rather than upward?

Nothing goes into the sky, the lantern body shades the source from anyone looking at the wall from a distance, and light lands on the ground where it is useful. On a boundary wall, a shared driveway or a dense street that matters more than the effect an upward lantern on a party wall is a complaint waiting to happen. The counter-argument is appearance: the upward GT-691 is the classic coach-lamp posture.

Is “Large” just a bigger version?

It is a parallel range rather than a size option, using bracket reference GT-691 and offering fewer arrangements than the standard VIENNA. Decide the largest arrangement your scheme needs first, then pick the family and do not mix the two sizes on one property, because a large lantern beside a standard one reads as a mistake rather than a hierarchy.
