Every cabinet is cut for the 4,000 mm shell — the latitude bands, the truncations at top and bottom and the cable exits are tooled for this one diameter
8,775,955 pixels run as a single 2:1 canvas, so a stock equirectangular video maps without re-cutting
Front-service modules on magnetic carriers: one dead module comes off with a suction tool, no need to open the shell or hire a lift
Load ring, three-point rigging and a stamped connection detail are included in the drawing package
Max draw is 40.2 kW at 800 W/m² — we size the distribution board and the cable runs from this figure, not from a rule of thumb
Four metres at P3 puts 4,187 px on the equator, which is what makes full-motion brand content hold up under close inspection. Most builds this size ship in eight to ten crates and need a crane window booked with the venue.

Same shell, different module. The resolution and the price both move with the pitch — this table is the fastest way to see what you are choosing between.

FAQ
Practical questions
What resolution does a 4 m sphere give at P3?
4,189 × 2,095 px, about 8,775,955 pixels in total. The horizontal count is the circumference (12.57 m) divided by 3 mm; the vertical count is half that, because a sphere maps as a 2:1 equirectangular image.
How much does a 4 m LED sphere weigh?
Around 653 kg for the screen and shell together, assuming 13 kg per m² of surface. That is an estimate for early structural conversations — the final figure comes from the shell design and we issue it with the drawing set.
Can it be built in a different diameter?
Yes. Anything from 0.8 m to 20 m is quoted from a drawing; the sizes on this page are the ones with existing tooling, which is why they are cheaper and faster. An odd diameter means a new mould set, and that shows up as a separate line in the quotation.
