Daymeet TV Led Lights 4M Backlight for 55-75 inch TVs – RGBIC, USB-Powered with Remote, Bluetooth APP & Music Sync
Product description
What it is
Daymeet TV Led Lights are a 4-metre RGBIC backlight strip designed to sit behind a TV from 55 to 75 inches. It runs off a USB port at 5V, and uses an enhanced IC to display multiple colours on a single line for a rainbow-like effect. It also offers a broad palette of up to 16 million colours and more than 200 dynamic modes, plus music/voice sync to react to sound in the room.
How it works

The strip adheres to the back of your display via strong self-adhesive tape. Setup is meant to be straightforward: peel off the backing and fix it behind the screen. Control is versatile: a remote, Bluetooth app (DouCo StripX), or a simple USB-connected controller box with three buttons. The Bluetooth control requires enabling Bluetooth and pairing, with automatic reconnect usually present once set up.
Practical use and ambience


If you’re aiming to create a cinema-like atmosphere, day-to-day gaming mood, or a festive backdrop for parties, these lights offer a flexible palette. The rainbow-style effects are designed to run along the entire strip, with patterns that move or chase across the length of the TV. Music-synchronised modes make the backlight respond to beats in real time, which can heighten immersion in games or film scenes.

What stands out and what may not
On the plus side, the combination of an RGBIC setup and a large 4-metre length means richer colour and more dynamic scenes than standard single-colour backlights. The 5V USB power keeps wiring simple and tends to be safe for households with children. The broad compatibility with 55–75 inch screens means it’s a versatile fit for many living rooms or bedrooms.
On the downside, the reliance on a USB supply means you’ll need a spare USB port or a powered hub to ensure stable brightness for longer sessions. The stock description mentions many modes and the rainbow effect, in practice, some users may prefer a simpler, calmer backlight for late-night viewing, and this kit might feel a bit busy for that use. Also, as with any adhesive-backed strip, longevity can hinge on the TV’s surface and room temperature, if the tape weakens, the strip may need reapplication.

Who it’s for


This backlight is reasonable for households looking to upgrade their viewing ambience without buying bespoke lighting. It’s suited to movie nights, gaming sessions, and general room illumination around a large TV. If you enjoy immersive, reactive lighting and don’t mind managing a few setup steps, you’ll likely find value here.
Who it isn’t the best for

If you want pure minimalism or a single, constant backlight colour, this RGBIC strip is more feature-rich than you might need. It’s also not ideal if your TV area cannot spare a USB port or if you’re after a discreet, barely-there lighting effect. For those craving extremely bright, colour-pure effects in a compact footprint, there may be simpler options that keep the setup tidier.
When it makes sense to buy
Consider this when you want a multimedia ambience upgrade that responds to audio and offers varied lighting scenes. If your space accommodates a 4-metre strip and you value adjustable colour dynamics, ties to music, and app control, it’s worth considering.



What to check before buying
- Confirm your TV sits within the 55–75 inch range and that a spare USB port is available for power.
- Note that Bluetooth app control requires downloading the DouCo StripX app and pairing your device.
- Check the installation surface, ensure the TV back is reasonably clean and smooth to maximise tape adhesion.
- Consider how the brightness and colour mix will sit in your room lighting to prevent glare or overpowering colours.
A practical use example

During a quiet movie night, you might set a soft blue gradient behind the TV with a gentle wave effect turning on during action scenes. For a gaming session, you could switch to a high-energy rainbow chase that follows the beat of the soundtrack, using the mic input to sync to in-game sound cues. It can also be a playful backdrop for birthday or festive gatherings when paired with a warm or colour-changing scene.
FAQ
- Do I need a smart hub for this to work? No, it primarily uses a USB power source and the included remote/app controls.
- Can I control it with a mobile app if I don’t use Bluetooth? The app requires Bluetooth pairing, otherwise, the remote or controller box will suffice.
- How easy is the removal? The tape is designed to be strong but can be lifted with some care, residue may occur on delicate painted surfaces.
Is it worth it?
A solid pick if you value flexible lighting, music-reactive modes and an immersive backdrop for a large TV. It may not be the best fit if you want a low-profile, minimal light or if USB power is a concern. If you prioritise ambience and easy app/remote control, this kit offers a practical upgrade without committing to a full smart lighting system.
