Applications

Six recipes for WLED

For each application: which strip, which controller, how big the power supply, how to set it up and where projects typically fail.

Shopping list

  • StripPixel strip warm white 24 V, 48 pixels/m
  • Length (example)4 m
  • Power67 W
  • Power supply24 V, from 81 W

Alternatives: Pixel strip warm white 24 V, 48 pixels/m, Pixel strip RGB 24 V, 10 pixels/m; 4336-116-RF, 4336-616, 4336-211

Kitchen & living

Task light that turns into ambience at night

How to

  1. Mount the strip in an aluminium profile with opal diffuser: no visible dots, better cooling.

  2. Choose a controller with relays so the strip is unpowered when off.

  3. Create two presets: “Cooking” (100 %, neutral) and “Evening” (30 %, warm). Put them on a push button: short = on/off, long = switch preset.

  4. Under LED Preferences set “Turn LEDs on after power up” and a boot preset so the wall switch works as usual.

Effect tip

Solid in warm white, “Wipe” from left to right when switching on

Pitfall

Pixel strips behind glass or above a glossy worktop show every dot. Dense strips (e.g. 336 LEDs/m) and a deep profile prevent that.

Stairs & hallway

Light that walks with you, step by step

How to

  1. One strip section per step; connect the sections in series and watch the data direction (arrows).

  2. Connect a motion sensor to a free input and set it up as “PIR” in Button Configuration. It recalls a preset.

  3. For a real step animation from bottom and top there is the “Animated Staircase” usermod. It needs a custom WLED build.

  4. Night light: set Timed Light to e.g. 2 minutes with fade and low brightness so nobody is dazzled.

Effect tip

“Wipe” as switch-on transition; motion sensor (PIR) as button input

Pitfall

Long jumper cables between steps lengthen the data line. Beyond a few metres of free cable a signal booster helps. Plan power injection at top and bottom.

Shopping list

  • StripPixel strip RGB 5 V, 60 pixels/m (heavy copper)
  • Length (example)3.5 m
  • Power58 W
  • Power supply5 V, from 70 W
  • Controller4336-USB

Alternatives: Pixel strip RGB 5 V, 60 pixels/m (heavy copper), Digital Vision strip RGB 5 V, 60 pixels/m; 4336-USB, 4336-310

TV, gaming & desk

The wall behind the screen lights up with it

How to

  1. Mount the strip on the back of the device, about 2 cm from the edge. Start at the bottom centre so corners are symmetrical.

  2. Small setups (under 1 m) run directly on the mini controller via USB. Larger ones need their own 5 V power supply.

  3. Set the current limiter (ABL) to the power supply's value. With USB power this is mandatory.

  4. For ambilight that follows the picture: software such as Hyperion or HyperHDR captures the image and sends the colours to WLED via DDP.

Effect tip

“Colorloop” or “Pacifica”; real ambilight via Hyperion/HyperHDR over DDP

Pitfall

A 5 V strip with 60 LEDs/m draws 3.3 A per metre at full white. A 3 A USB charger is not even enough for one metre. Without the current limiter the controller reboots.

Shopping list

  • StripPixel strip RGB 24 V, 10 pixels/m
  • Length (example)8 m
  • Power104 W
  • Power supply24 V, from 125 W
  • Controller4336-616

Retail & shop window

Products by day, a stage at night

How to

  1. Create your own palette in brand colours in the palette editor (WLED 16 and later).

  2. Presets for day, evening and night, started by schedules (Time & Macros). The time comes via NTP.

  3. Connect the controller by Ethernet: shop windows are often far from the router, and metal frames weaken Wi-Fi.

  4. Staff use the ESP-NOW remote, not the app. That keeps the configuration untouched.

Effect tip

Gradient in brand colours (“Running”, “Colorloop”), schedule via NTP

Pitfall

Fast blinking and strobe effects in a shop window look cheap and can endanger people with photosensitive epilepsy. Slow gradients look more premium.

Shopping list

  • StripPixel strip RGB 24 V, 10 pixels/m
  • Length (example)10 m
  • Power130 W
  • Power supply24 V, from 156 W
  • Controller4336-616

Alternatives: Pixel strip RGB 24 V, 10 pixels/m, Digital Vision strip RGB 5 V, 144 pixels/m; 4336-616, 4321-WL4

Trade fair & events

Set up, plug in, start the show

How to

  1. Set up and back up the complete configuration before the fair (cfg.json, presets.json). On the stand, just plug in.

  2. Bring your own small router and connect all controllers by LAN: exhibition hall Wi-Fi is overloaded.

  3. Synchronise several controllers via UDP sync or drive them centrally from xLights over DDP.

  4. For logos or lettering plan dense 5 V strips (144 pixels/m) with a power feed every metre.

Effect tip

Built-in effects as a playlist, or a show from xLights over DDP / Art-Net

Pitfall

Trade fairs have the organiser's fire safety and electrical rules. Power supplies and cables must comply; the stand builder clarifies this in advance.

Facade, garden & holidays

Roof edge, fence and tree, controlled centrally

How to

  1. Choose strips in an IP66 silicone sleeve: selectable in the shop configurator for the 24 V WS2811 and the 5 V WS2812B-V5 strip; IP67/IP69K and other strips on request.

  2. Controller and power supply belong in a sealed enclosure (at least IP65) in a dry spot. The controllers themselves are IP20.

  3. Choose 24 V: less current, less voltage drop along long roof edges.

  4. Schedules: e.g. on at sunset, off at 11 pm. The time comes via NTP.

Effect tip

“Twinklefox”, “Fairy” or calm warm white; schedule by time of day

Pitfall

Outdoor installations and anything on 230 V mains belong in the hands of a qualified electrician. Condensation in the enclosure is the most common cause of failure.
