Long low-voltage runs
A physical 45 m line is not the same as a permissible 45 m feed distance. Power zones and injection points are calculated from the selected load and cable, not from length alone.

MADRIX LED Ceiling System for Large Indoor Projects
Specify addressable RGB or RGBW linear lighting, distributed control, zoned power, cabling, and commissioning as one coordinated project package.
Direct answer
A large MADRIX LED ceiling is normally divided into repeatable power and data zones. A complete package combines addressable linear fixtures, Art-Net or supported sACN transport, matched pixel controllers, local power supplies, injection wiring, connectors, and a tested address map. Final quantities depend on pixel density, watts per metre, run layout, cable resistance, and controller limits.
The ceiling is one visual surface, but it cannot be one electrical run.
Large ceiling projects become unreliable when fixture selection, controller capacity, voltage drop, and cabling are sized separately. The engineering task is to make every zone behave as one mapped canvas without hiding the limits of the hardware.
Pixel and universe capacity
RGB and RGBW use different channel counts. Pixel density, universes, controller outputs, refresh requirements, and design reserve must be checked together.
Mixed component risk
The LED IC, controller output protocol, connectors, power supply, and software patch must agree. A compatible label on one component does not prove the complete chain.
Five layers from the MADRIX canvas to each ceiling zone
This is the review sequence used for early system design. The selected products and quantities are fixed only after the project inputs are known.
- 01
MADRIX 5 software
Build the virtual matrix, content, patch, and universe plan on the control computer.
- 02
Ethernet lighting transport
Send mapped data over Art-Net. MADRIX also supports sACN/E1.31, but the selected controller or gateway must independently support the same mode.
Software support does not automatically prove controller support.
- 03
Network and distributed controllers
Place switches and controllers by zone so data distribution, port loading, service access, and cable distances remain reviewable.
- 04
SPI or DMX fixture output
Match controller output to the LED IC and fixture protocol, then verify pixels per output, channels, refresh rate, and reserve.
- 05
Local power zones
Size supplies, protection, cable, connectors, and injection points for each repeatable zone rather than forcing current through one long feed.
Protocol reference: MADRIX 5 lists Art-Net and Streaming ACN (sACN/E1.31). The complete hardware path must still be confirmed for the selected controller.
Choose the visual result and service strategy before the SKU
The right fixture is the one that meets the ceiling geometry, pixel resolution, white-light requirement, access plan, and control architecture together.
RGB or RGBW
- Selection guidance
- RGB suits saturated effects. RGBW adds a dedicated white channel when cleaner white light is part of the brief.
- Verify before quotation
- Channel count, controller capacity, power load, desired white quality
Pixel strip, neon, or rigid bar
- Selection guidance
- Strip is compact, silicone neon produces a continuous diffused line, and a rigid bar provides a protected straight profile and repeatable mounting.
- Verify before quotation
- Viewing distance, diffusion, bend direction, mounting and service access
12 V, 24 V, or long-run options
- Selection guidance
- Use the voltage and zoning plan that keeps conductor loss, current, connector loading, and supply distribution within the reviewed limits.
- Verify before quotation
- Watts per metre, cable resistance, feed topology, allowable voltage at the far end
Pixel density
- Selection guidance
- Higher density improves spatial resolution but increases channels, universes, controller ports, data traffic, power, and cost.
- Verify before quotation
- Content resolution, viewing distance, refresh target and total mapped pixels
Indoor protection level
- Selection guidance
- Select the construction for dust, cleaning, condensation, plenum or venue requirements, and the expected maintenance method.
- Verify before quotation
- Installation environment, local code, connector and enclosure requirements
Long-run planning
Treat every 45 m line as a layout input—not a one-end-feed assumption.
Power injection spacing and controller placement cannot be derived from length alone. Use the calculators for a first screening pass, then have the selected cable, fixture, connectors, topology, protection, and local electrical requirements reviewed together.
Inputs needed for a reviewable first pass
- Selected fixture voltage and measured watts per metre
- RGB or RGBW pixel density and total channel count
- Actual conductor resistance at the intended installation temperature
- Permitted far-end voltage and connector current
- Power-feed topology, supply locations, protection, and service access
- Controller ports, universes, supported IC, refresh target, and design reserve

Questions buyers ask before comparing suppliers
Can MADRIX control both RGB and RGBW ceiling fixtures?
Yes, MADRIX can map RGB and RGBW fixtures. The fixture definition, channel count, controller capacity, and output protocol still have to match the selected LED product.
Does every Pileds Art-Net controller support sACN?
Do not assume so. MADRIX supports sACN/E1.31, but the selected controller or gateway must list and be tested for the same protocol. Pileds will confirm the exact hardware path during engineering review.
Can a 45 m line of 12 V addressable LED be powered from one end?
That cannot be confirmed from length and voltage alone. Watts per metre, cable resistance, allowable voltage drop, connector limits, injection topology, and local electrical requirements determine the power-zone design.
How many controllers and power supplies will the project need?
The count depends on total pixels, RGB or RGBW channels, universes, pixels per controller output, design reserve, fixture watts per metre, zone layout, cable, and supply placement. A reliable count requires those inputs.
Can Pileds supply the complete system rather than LED only?
Pileds can prepare a matched project package covering the selected LED fixtures, controllers, power supplies, cables, connectors, accessories, and engineering documentation. Final scope is listed in the quotation and BOM.
What will the quotation state about MOQ, lead time, datasheets, and warranty?
Those terms vary by the selected standard or customized build. The project quotation should state the applicable MOQ, production lead time, available technical files, warranty scope, exclusions, and support plan for the chosen configuration.
