LED wall power calculator

Enter the wall size and a W/m² figure and you get the maximum and typical kilowatts, the amps and the circuit count, sized the way working crews size them: on the full-white maximum at an 80% derate. Pick a real panel to use its datasheet figure instead of a guess.

Wall power

Typical max power, W/m²:
Max draw
23.0 kW
full white, full brightness
Typical
7.7 kW
normal content: generator sizing, not circuits
Amps
100 A
at 230 V on max, summed across all circuits
Circuits
8× 16 A / 230 V
sized on max at 80% derate (2,944 W usable each)

Circuits are sized on maximum draw. One white flash frame must not open a breaker. Electrical work must be verified by a qualified electrician where the law requires one. For feeders, distros and the full run plan, open the planner.

LED wall power, answered

How much power does an LED wall use?

Published maximum draw in the database runs from 168 W/m² (Sharp LD-FE093, a 608 × 342 mm fixed-install cabinet) to 1,387 W/m² (Digital Projection RCS-G 1.9 Medium, a 500 × 750 mm rental and fixed-install cabinet); the middle half of the indoor rental panels sits between 500 and 680 W/m². Multiply by wall area for maximum draw, and expect typical content to draw roughly a third of that.

Why size circuits on maximum instead of typical draw?

Content is unpredictable (one white flash frame, one test pattern, one source failing to a white screen), and the distribution has to survive all of it without opening a breaker mid-show. Typical draw answers a different question: what to tell the venue or which generator to order.

How many amps does an LED wall draw?

Amps are the maximum draw divided by the supply voltage. A 4 × 3 m wall of a 600 W/m² panel draws up to 7,200 W, which is 31 A at 230 V or 35 A at 208 V, spread across the circuits the calculator counts (each 16 A circuit carries 2,944 W at an 80% derate). On a three-phase distro the total splits across the three phases.

How many LED panels fit on one 16 A circuit?

A 16 A / 230 V circuit at an 80% derate carries 2,944 usable watts. Divide by the panel's maximum per-cabinet draw: eighteen 160 W cabinets, nine 320 W cabinets. Always the datasheet maximum, never the typical figure.
