The Domus GT-555 Siena is a 250mm sphere on a post 1,570mm recorded height, 380mm deep, IP43,taking one E27 lamp, in aluminium. Five powder-coated colours.

This item is made to order

Domus builds this fitting to order and asks for up to 10 business days for productionbefore it ships. That is the trade-off for the finish choice the body ispowder-coated in your colour after ordering. Order a matched pair or run together; alater powder-coat batch is not guaranteed to match.

Do not buy a Siena post by its size name

We compared all 14 Siena posts in this catalogue against their names. Thenames and the recorded heights do not agree.

• Eight pairs across the range are named differently and record the same height.
• Compare like with like: a twin-head post is taller than a single-head one, whichis expected. The problem is inside a single head count where two different namesgive the same height.
• We cannot tell whether the heights are wrong or the naming is, and we are not goingto guess.
• What to do instead: buy on the recorded height, not the size word and if theheight matters against a fence, a gate or a sight line, ask us and we will measure a physicalpost. On a made-to-order fitting that is worth doing before the ten days start.

The sphere is the choice, and it comes in three sizes

• 200mm 250mm 300mm across the Siena range. This is the250mm.
• A sphere is an omnidirectional diffuser it throws light in every directionrather than down. Which makes it a presence light rather than a task light: it marks apath and lights the space around it softly, and it does not put a bright pool on the ground.
• So a sphere is seen as much as it lights. At 250mm on a 1,570mm post itsits at about chest-to-shoulder height and reads as a glowing object in the garden.
• Which also means glare matters. A bright lamp in a sphere is visible from everyangle use a warm, modest E27 LED, not a bright cool one.
• Step up to the 300mm on a wider frontage and down to the 200mm where thesphere would dominate.

An E27 holder with no maximum wattage

• One E27 lamp, not included, and no maximum recorded anywhere the same gap thatruns through the traditional Domus ranges.
• An E27 LED at 810W, warm at 27003000K, rated for enclosedand damp use, is what we would fit.
• Check the lamp fits the sphere’s opening. E27 LEDs vary a great deal in length andgirth; a compact globe is safer than a long candle.
• Ask us before anything above about 15W.

And no footing specification

No footing depth, base plate size, fixing pattern or wind rating is recorded on anySiena post. A 250mm sphere at 1,570mm presents real sail area in an exposedgarden. Tell us the site and the soil and we will get the footing detail from Domusbefore your concreter is there.

Where it works

• Driveways and path edges, repeated at regular centres, as a rhythm of glowingspheres.
• Formal and period gardens, where the sphere form suits.
• Alongside Siena wall brackets, pillar mounts and pendants on the same property.
• Not where you need light on the ground a sphere spreads rather thanpools.
• IP43, so not a wash-down or coastal front-line position.

Questions

Is the “Tall” post taller than this “Medium” one?

Not on the recorded figures both record 1,570mm. We compared all 14 Siena posts and found eight pairs named differently that record the same height: single-head medium and tall are both 1,570mm, and twin-head short and medium are both 1,330mm. That is within a single head count twin-head posts are taller again, which is expected. We cannot tell whether the heights are wrong or the naming is, so buy on the recorded height rather than the size word and ask us to measure a physical post if the height is critical.

How long will it take to arrive?

Domus builds this to order and asks for up to 10 business days for production before it ships. It is not held in stock the body is powder-coated in the colour you choose after ordering, which is why five colours are offered. If you are installing a run, order them together: a second order later starts its own ten days, and a later powder-coat batch is not guaranteed to match.

Which sphere size should I choose?

Three are made 200mm, 250mm and 300mm and this is the middle one. A sphere is seen as much as it lights, so the size is largely a question of presence: 300mm suits a wide frontage or a generous entrance, 200mm suits a narrow path where a larger sphere would dominate, and 250mm is the general choice. All three take the same E27 lamp, so the size does not change the output.

Will it light my path?

It will mark it rather than light it. A sphere is an omnidirectional diffuser it throws light in every direction rather than down so it gives soft presence and a glowing object in the garden, not a bright pool on the ground. If you need light on a walking surface, a hooded path light such as the DUSK-PATH range does that job properly, and you can use the Siena spheres alongside for the look.

What lamp should I use?

An E27 LED at 810W, warm at 27003000K, rated for enclosed and damp use. No maximum wattage is recorded anywhere in this range, so ask us before going above about 15W. Warm and modest matters more on a sphere than on a hooded fitting, because the lamp is visible from every angle a bright cool globe in a sphere becomes the brightest thing in the garden. Check the lamp fits the opening too: E27 LEDs vary a lot in length and girth.

What footing does it need?

Not recorded on any Siena post no depth, base plate size, fixing pattern or wind rating. A 250mm sphere at 1,570mm presents real sail area in an exposed garden, so it is worth settling. Tell us the site and the soil and we will get the footing detail from Domus before your concreter is there; it goes into concrete long before anyone tests the light.

Is the Siena sphere available other ways?

Yes 24 listings in all. The same sphere is sold as a wall light, a wall bracket, four pillar mounts, three pendants and fourteen post arrangements including twin and triple heads. No listing mentions the others, which is worth knowing: the same sphere on the gate piers, the garage wall and over the front door is what makes a property read as one scheme.
