Ambilight Plug & Play Kit

Unbox. Plug in. Your TV glows.

GST included · ships pan-India

This is the kit I hand to people who want the result without the weekend. The ESP32 arrives with WLED already flashed, already configured and already bench-tested with this exact LED strip — I power every board up and run a colour sweep before it goes in a box. The connector is pre-soldered to the strip lead, so there is no iron, no flux and no chance of lifting a pad. You stick the strip to the back of your TV, plug two connectors together, join your Wi-Fi, and you are done. Everything after that — effects, screen sync with SignalRGB, scheduling — is software.

What's in the box

  • ESP32 dev board with WLED pre-installed, configured and tested before shipping
  • 5 m WS2812B addressable LED roll (60 LEDs/m, 300 LEDs), connector pre-soldered to the ESP32 lead
  • Custom 3D-printed enclosure for the ESP32
  • 5V 4A power adapter with DC barrel connector
  • WLED's automatic brightness limiter pre-set to 3,800 mA, so the adapter is never overloaded
  • 3M adhesive clips for mounting
  • Printed QR card linking to the setup guide in the app and on the site

What else you need

  • A TV or monitor, 32" to 75". The kit sticks to the back — it never plugs into the TV, so any brand works.
  • A Windows PC running SignalRGB, but only if you want the lights to follow what is on screen. Everything else works from your phone.
  • 2.4 GHz Wi-Fi. The ESP32 has no 5 GHz radio.

Before you buy

Questions people actually ask

Questions people actually ask

Do I need a PC for this?
Not for the lights. The kit runs standalone on your Wi-Fi — effects, colours, brightness and schedules all work from the WLED app on your phone. You only need a Windows PC if you want the LEDs to follow what is on the screen in real time, which is done with SignalRGB.
Will 300 LEDs be enough for my TV?
A 55" TV has roughly a 3.8 m perimeter, which is about 228 LEDs at 60/m. A 65" is about 4.4 m, or 264 LEDs. So 5 m covers everything up to 75" with strip to spare. You cut the leftover off at a marked cut line and set the real LED count in WLED — the guide walks you through it.
Why is the brightness limited to 3,800 mA?
Three hundred WS2812B LEDs at full white draw about 18 A. No sane adapter does that. WLED's limiter keeps the total draw under the adapter rating by scaling brightness automatically, which is what makes this kit safe to leave running. For ambilight behind a TV you will never notice — you are lighting a wall, not a room.
Does it work on 5 GHz Wi-Fi?
No. The ESP32 has a 2.4 GHz radio only. Most Indian routers broadcast both bands under one name, which is fine — just make sure 2.4 GHz is enabled. If your router splits the bands, join the ESP32 to the 2.4 GHz one.
What if I want to solder and learn instead?
Buy the DIY Ambilight Builder Kit. Same LEDs, same controller, but you flash the firmware and make the joints yourself, and the soldering iron and safety gear are included and yours to keep.
Can I control it when I am not at home?
Out of the box, no — and that is deliberate. It stays on your local network, which is the safe default. WLED supports MQTT and Home Assistant if you want to bridge it yourself.
