The number that surprises people

A 1.5 m indoor LED sphere at P2.5 typically lands between USD 9,000 and USD 16,000 depending on specification, before shipping and site works. The spread is not haggling room — it is the difference between six cabinet moulds and eleven, between a bolted frame and a welded one, between one controller and two.

Line 1 — LED modules and cabinets (45–55%)

For a 1.5 m sphere the surface area is about 7 m². At P2.5 that is roughly 1.1 million pixels, and the module cost scales almost linearly with pixel count. The cabinets are where the oddity lives: each latitude band has a different curve radius, so the aluminium cabinet is a different part number. Six bands means six tooling sets, and tooling is a one-off cost per shape, not per square metre.

This is why a 2.5 m sphere often costs less per square metre than a 1 m sphere. Same tooling spread over four times the area.

Line 2 — Curved cabinet tooling (8–15%)

Tooling is the line most buyers try to cut, and the one that ruins the result if they succeed. A cheap tool means the cabinets do not butt together cleanly, and on a sphere every seam is visible from some angle. If a supplier's sphere quote is dramatically below everyone else's, ask how many moulds they are cutting.

Line 3 — Control and pixel mapping (8–12%)

A sphere is not a rectangle, so the controller has to know the spherical coordinates of every pixel. That is a mapping file, usually generated from the same CAD model used for tooling. Novastar and Colorlight both handle it; the cost is in the mapping work, not the hardware. If your supplier cannot supply the mapping project, budget for a media server instead, and that is a four-figure addition.

Line 4 — Structure and rigging (10–18%)

A 1.5 m sphere weighs around 95 kg. The steelwork needs to hold three times that, and if it hangs over a public space it needs a certified anchor and usually a secondary safety bond. Budget the structure with the screen, not after. On suspended installs the steel often costs more than the difference between P2.5 and P3.

Line 5 — Content adaptation (0–6%)

Anything shot in 16:9 has to be re-projected into 2:1 equirectangular before it looks right on a ball. Some clients do this in-house with After Effects and a plug-in; others ask us to pre-render their launch video. It is a small line but it is the one that decides whether opening night looks good.

Line 6 — Shipping, duties and site works (5–20%, highly variable)

A 1.5 m sphere ships in three crates, around 1.4 m³ and 140 kg gross. Sea freight to Europe runs roughly USD 400–900 depending on the season; air freight is three to four times that. Installation by two technicians is typically two days on site. If the ceiling needs a genie lift or scaffolding, that is a site cost the client carries.

What you can cut, and what you should not

Cuttable: pitch (P3 instead of P2.5 saves 15–20% and is invisible past 3 m), hemisphere instead of full sphere (saves around 45%), and cabinet count by increasing band height. Not cuttable without regret: tooling quality, structure certification, and the pixel map. Those three are what separate a ball that reads as one surface from a stack of rings with visible joins.
