DOMUS GT-537 Siena Sphere Exterior Pendant

The Domus GT-537 Siena is a 300 mm sphere pendant — 600 mm recorded drop, 370 mm deep, IP43, taking one E27 lamp, in aluminium. Five powder-coated colours.

⛔ This item is made to order

Up to 10 business days for production before it ships. ⚠ Order a matched set together — a later powder-coat batch is not guaranteed to match.

✅ It is the best-recorded of the three Siena pendants

⭐ Only this one records everything — the 200 mm records no lamp base or depth, and the 250 mm records its material as Glass where the other two record Aluminium. ✅ So you can specify this one from the page.

⚠ 370 mm deep, and the deepest of the three

• 370 mm against the 250 mm pendant's 330 mm. ⛔ The 200 mm records none.
• ⚠ On a pendant, the depth is the swing radius as much as the projection. Under a narrow soffit or close to a wall, 370 mm is enough to matter — and a pendant that touches a wall when it swings will mark both.
• ⭐ Check the clearance in both directions, not just the drop.

⭐ All three pendants share a 600 mm drop

• 600 mm across the 200, 250 and 300 mm spheres.
• ⭐ So different sphere sizes hang level — a graduated row at one height is a deliberate arrangement, and it works only because the drop is constant. Stated on no listing.
• ⚠ On a 2.4 m covered ceiling that puts the sphere at about 1.8 m. ⚠ At 300 mm this is the largest of the three, so at 1.8 m it will feel close on a small porch — the 200 mm GT-535 is the lighter option there.
• ⚠ Whether the drop can be shortened is not recorded on any of the three. Ask us before a low ceiling.

⭐ The largest sphere glows the most evenly

• ⭐ The same E27 lamp behind a larger diffusing surface spreads more thinly, so the 300 mm sphere glows evenly where a 200 mm can show a bright spot.
• ⚠ It also reads as less bright for the same lamp — the output is unchanged, the apparent brightness is lower.
• ⭐ Which makes this the most comfortable of the three at eye level, and the one to choose where the pendant hangs somewhere people sit or stand under it.
• ⭐ Omnidirectional — it lights the ceiling as well as the ground, which is what makes a covered entry feel generous.

⛔ No maximum wattage recorded

One E27 lamp, not included, no maximum in any source — the same gap across the whole Siena range. ✅ 8–10 W E27 LED, warm at 2700–3000 K, enclosed and damp rated. ⚠ Ask us above about 15 W.

Where it works

• Generous porches, verandahs and covered entries, where a 300 mm sphere holds the scale.
• Above seating, where the even glow is most comfortable.
• Matched with GT-537-sized Siena posts and pillar mounts at 300 mm.
• ⚠ Not on a small porch at standard ceiling height — it will feel close at 1.8 m.
• ⚠ Not under a narrow soffit without checking the 370 mm depth.
