GT-570 Siena - Twin Spheres Medium Exterior Posts

The Domus GT-570 Siena twin-sphere medium post is a twin-head exterior post — 1,330 mm high, 730 mm wide, Ø300 mm spheres, 240 V, IP43, in five colours.

⭐ 1,330 mm is deliberately low — and that is a different job

• ⭐ The lantern posts elsewhere in this catalogue run 2.1 to 2.5 m. ⭐ This is 1,330 mm — roughly waist to chest height.
• ⭐⭐ A TALL POST LIGHTS AN AREA. A LOW ONE MARKS A LINE. ⭐ At 1.33 m the spheres are below eye level for most adults, so you look down at them rather than up — and what they do is define an edge: the side of a drive, the boundary of a lawn, the run of a path.
• ⭐ THAT SUITS A RUN, WHERE THE TALL LANTERN POSTS SUIT A FOCAL POINT. ⭐ Three or four of these down a drive reads as a rhythm; three or four 2.4 m lantern posts reads as an avenue, which is a much heavier statement.
• ⭐ IT IS ALSO THE LESS OBTRUSIVE CHOICE FROM INSIDE THE HOUSE. ⭐ A glowing sphere at 1.33 m sits below most window sight lines; a lantern at 2.4 m is in them.

⭐ Twin spheres at 730 mm across — the proportion is unusual

• ⭐ Two Ø300 mm spheres spanning 730 mm on a 1,330 mm post. ⭐⭐ THE SPHERES ARE LARGE RELATIVE TO THE POST — together they are more than half its height across.
• ⭐ SO THIS READS AS TWO GLOBES HELD UP RATHER THAN AS A POST WITH LIGHTS ON IT. ⭐ It is a sculptural object more than a light fitting, which is the reason to choose it and also the reason to place it carefully.
• ⚠ THE 650 mm FOOTPRINT IS SUBSTANTIAL. ⭐ It will not fit a 600 mm bed, and the footing has to be wider still.
• ⭐ TWO LARGE SPHERES ALSO CATCH WIND — ⭐ less than a tall post would, being lower, ⚠ but a 730 mm span of solid form is a real sail area and the footing matters.

⭐ Two lamps, and in spheres they must match exactly

⭐ Two lamps are needed and neither is included. ⭐⭐ MATCHING MATTERS MORE ON SPHERES THAN ON LANTERNS, because a sphere is an evenly lit surface with nothing to break it up — any difference in colour temperature or brightness between the two is read directly as a difference in the objects themselves. ⭐ On a lantern, glazing bars and shadows disguise a small mismatch; on a sphere nothing does. ⭐ Buy them as a pair from one batch and replace them as a pair. ⭐ Use opal globe-shaped lamps sized to fill the Ø300 mm spheres — ⚠ a compact lamp lights the lower half and leaves a visibly dim crown, which on a sphere at below eye level is exactly what you are looking at. ⭐ Warm rather than cool.

⚠ IP43, and what a low position exposes it to

• ⭐ IP4X keeps out wires and most insects; IPX3 covers spraying water to 60° from vertical. ⛔ Not driving rain, hosing or sprinklers.
• ⚠ AT 1.33 m THE SPHERES ARE WITHIN SPRINKLER RANGE, which a 2.4 m lantern is not. ⭐ Check the irrigation layout before setting the post — a pop-up sprinkler aimed upward reaches further than people expect, and IPX3 does not cover a direct jet.
• ⚠ IT IS ALSO WITHIN REACH OF MOWERS, EDGERS AND FOOT TRAFFIC. ⭐ Keep the base clear of mulch and soil, and expect the bottom 300 mm of the post to take the damage.
• ⭐ THE SPHERES THEMSELVES SHED WATER WELL — ⭐ a curved surface has no horizontal seam to hold it, which is where a lantern usually lets water in.

⭐ The Siena shape across a property

⭐ The sheet names related references — the GT-502 and GT-503 wall brackets, the GT-504 pillar mount and the GT-544/545. ⭐⭐ SO THE SIENA SPHERE CAN RUN FROM THE GATE PIERS TO THE DRIVE TO THE WALL BESIDE THE DOOR, and read as one scheme because it is the same form. ⭐ Using spheres for the run and a pair of pillar-mounted spheres at the entrance is exactly what the range is built for. ⚠ Tell us the arrangement you want and we will confirm which references it takes.

⛔ Made to order

Allow up to 10 business days for production. ⭐ Published, which is unusual in this catalogue.

✅ What is published

Where it works

• ⭐⭐ Marking the edge of a drive or lawn — ⭐ a rhythm, not an avenue.
• ⭐ Where a tall post would be in window sight lines.
• ⭐ With Siena pillar mounts at the entrance — ⭐ one scheme.
• ⚠ Not within sprinkler throw — ⭐ check the irrigation first.
• ⚠ Not in a bed under about 800 mm — ⭐ 650 mm base.

Specifying it

Twin-sphere exterior post. 1,330 mm high, 730 mm wide, 650 mm footprint, Ø300 mm spheres. Two lamps required, neither included. 220–240 V. IP43. Aluminium. Five colours. Made to order, up to 10 business days. 1-year warranty. ⭐ AT 1,330 mm THIS IS DELIBERATELY LOW, AND THAT IS A DIFFERENT JOB FROM THE 2.4 m LANTERN POSTS ELSEWHERE IN THIS CATALOGUE. A tall post lights an area; a low one marks a line. At this height the spheres sit below eye level for most adults, so you look down at them rather than up, and what they do is define an edge — the side of a drive, the boundary of a lawn, the run of a path. That suits a RUN where tall lantern posts suit a focal point: three or four of these down a drive reads as a rhythm, where three or four 2.4 m lantern posts reads as an avenue. ⚠ AT 1.33 m THEY ARE ALSO WITHIN SPRINKLER RANGE, which a tall post is not — check the irrigation layout before setting the post.
