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
IP65 sealing on cabinet joints, driver covers and cable glands — the build is tested as a sealed assembly, not per component
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, eight-point rigging and a stamped connection detail are included in the drawing package
Max draw is 50.3 kW at 1,000 W/m² — we size the distribution board and the cable runs from this figure, not from a rule of thumb
Four metres is the most ordered outdoor diameter: big enough to be seen from a road, small enough to ship in standard crates. It is also where clients start specifying a media façade controller instead of a single player.

FAQ
Practical questions
What resolution does a 4 m sphere give at P4?
3,142 × 1,571 px, about 4,936,082 pixels in total. The horizontal count is the circumference (12.57 m) divided by 4 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 905 kg for the screen and shell together, assuming 18 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.
