Addressable LED Driver IC Guide: WS, SK, TM & UCS Compared

Choose the LED fixture and its driver IC together, then match the controller output, network input and software. An IC name alone does not specify a complete lighting system. Use this guide to identify what needs checking, then open the detailed comparison for that decision.

Start with the effect and the addressable pixel

Decide whether the installation needs individual points, groups of LEDs, or whole fixtures to change together. Record the number of independently controlled pixels per zone—not just the number of LED packages or metres of strip. RGB and RGBW also need different channel maps; a dedicated white channel is a fixture requirement, not a feature that every IC variant provides.

For strip projects, use the pixel LED strip selection guide to settle colour channels, pixel grouping and supply requirements before selecting control hardware.

Check the IC and the finished fixture separately

An external driver and an integrated driver create different fixture layouts. Neither the family name nor the package appearance establishes the finished strip's voltage, cut unit, current or environmental rating. Ask for the exact fixture model, IC variant and current datasheet.

• WS2811 vs WS2812B: compare external and integrated driver arrangements, then confirm the actual cut unit and grouping.
• SK6812 vs WS2812B: review the colour-channel choice; specify the exact RGB or RGBW variant rather than treating the family name as a complete specification.
• WS2815 vs WS2812B: compare the fixture's supply and backup-data arrangement; verify the wiring and the stated failure conditions on the selected model.

Separate network input from fixture output

Art-Net transports DMX data over Ethernet. A receiving node or controller converts that data into the output required by the fixtures. Art-Net support therefore does not, by itself, establish support for a particular pixel IC. The official Art-Net terminology explains this network-to-output distinction.

Use this check sequence when comparing a controller:

Read DMX512 vs Art-Net for the transport and wiring decision, or sACN vs Art-Net when choosing between network inputs. Do not infer the controller's output compatibility from either protocol label.

Estimate capacity before committing to a model

Enter the independently controlled pixel count and channel map into the controller capacity calculator. Use its assumptions to estimate channels, universes and ports. Network universes are not physical output ports, and the estimate is not a controller rating.

Check the actual model's supported ICs, per-port and total limits, refresh requirements, addressing behaviour and software configuration. The PILEDS LED controller range is the next place to compare available control options, not a promise that every listed controller suits the same fixture.

Turn the decisions into a project brief

For a network-controlled ceiling installation, the MADRIX LED ceiling system shows how fixtures, control, power distribution and cabling fit into one specification. Confirm software version and licensing against the final output configuration; hardware compatibility and software capacity are separate checks. See the MADRIX software documentation for its universe and patching terminology.

Use the project RFQ / BOM template to send PILEDS the fixture model or candidate, IC variant, RGB/RGBW map, pixel count by zone, desired effect, software version and network/output requirements. Mark unknown items for confirmation. A written compatibility check and a representative sample test should precede the final system order.
