Toplight P3.91 500x1000: 3.91 mm pitch, 500 by 1000 mm cabinet.
Cabinet geometry, weight, and power for the Toplight P3.91 500x1000, plus a calculator that turns a target wall size into cabinet counts, resolution, weight, and circuit loading.
Estimated specs. Toplight indoor/outdoor rental preset, 500x1000 cabinet (pro-toplight.com). Pitch/cabinet/refresh per manufacturer; power/weight/brightness are planning estimates, verify by cut sheet (outdoor brightness typically higher). Verify against the manufacturer cut sheet before ordering.
Pixel pitch 3.91 mm, 32,768 pixels per cabinet at 128 by 256
Cabinet 500 by 1000 mm (1.64 by 3.28 ft), 80 mm deep
12 kg (26.5 lb) per cabinet, about 24 kg per square metre
400 W peak per cabinet, 130 W average, about 800 W per square metre at peak
4 cabinets per 20A 120V circuit, 7 per 16A 230V circuit, at peak draw
The Toplight P3.91 500x1000 is indoor or outdoor 3.91 mm pitch LED with a 500 by 1000 mm cabinet carrying 128 by 256 pixels. Each cabinet weighs 12 kg (26.5 lb) and draws up to 400 W.
Those four numbers drive everything else on a build: how many cabinets reach your target size, what the wall weighs on the rigging, how many circuits the distro needs, and what resolution the processor has to feed.
Pixel pitch: 3.91 mm
Cabinet resolution: 128 by 256 (32,768 pixels)

Brightness: 1000 nits
Refresh rate: 3840 Hz
IP rating: IP54
Typical processor platform: Novastar
Power and circuits for the P3.91 500x1000
At the 400 W peak figure, one 20A 120V circuit carries 4 cabinets and one 16A 230V circuit carries 7. Both numbers apply the 80 percent continuous load derate (NEC 210.20, IEC 60364), which is the same maths WireFlow uses when it sizes a real wall.
Size the distro on peak, not average. Average draw of 130 W tells you what the wall costs to run over a show; peak is what trips a breaker during a white flash.
Peak per cabinet: 400 W
Average per cabinet: 130 W
Cabinets per 20A 120V circuit: 4
Cabinets per 16A 230V circuit: 7
Input voltage: 100 to 240 V at 50/60 Hz
Worked example: a 4 by 3 wall
12 Toplight P3.91 500x1000 cabinets in a 4 wide by 3 high grid make a wall 2 by 3 m (6.56 by 9.84 ft) at 512 by 768 pixels.
That wall weighs about 144 kg before rigging hardware and draws up to 4,800 W, which needs 3 circuits at 20A 120V or 2 at 16A 230V.
Wall size: 2 by 3 m
Resolution: 512 by 768 pixels
Weight: about 144 kg
Peak draw: 4,800 W
Circuits: 3 at 20A 120V, 2 at 16A 230V
Build this wall in WireFlow
The calculator above sizes a wall to your target dimensions with this panel's real cabinet geometry, then reports cabinet count, resolution, weight, and circuits. From there WireFlow can drop the finished wall straight into a diagram, already wired to its processors, and the cable schedule and power report update with it.

Frequently asked questions
What is the pixel pitch of the Toplight P3.91 500x1000?
3.91 mm. Each 500 by 1000 mm cabinet carries 128 by 256 pixels, or 32,768 in total.
How much power does the Toplight P3.91 500x1000 draw?
Up to 400 W per cabinet at peak, averaging around 130 W in normal content. That works out to roughly 800 W per square metre at peak. Size distro on the peak figure.
How many P3.91 500x1000 cabinets fit on one circuit?
4 on a 20A 120V circuit and 7 on a 16A 230V circuit, both at peak draw with the standard 80 percent continuous load derate applied.
How much does the Toplight P3.91 500x1000 weigh?
12 kg (26.5 lb) per cabinet, which is about 24 kg per square metre of wall. A 4 by 3 wall of them comes to roughly 144 kg before rigging hardware.
Are these Toplight specs exact?
Estimated specs. Toplight indoor/outdoor rental preset, 500x1000 cabinet (pro-toplight.com). Pitch/cabinet/refresh per manufacturer; power/weight/brightness are planning estimates, verify by cut sheet (outdoor brightness typically higher). Verify against the manufacturer cut sheet before ordering.
Can I design a wall with this panel in WireFlow?
Yes. Pick this panel, give it a target size, and WireFlow works out the cabinet grid, pixel map, weight, and power per circuit, then places the wall into your diagram already wired to its processors. Free to start with three diagrams and no card.
