Daymeet TV LED Light Strip (4M) with RGB backlight, remote & music sync for 55–75 inch TVs
Product description
If you like your living room to feel a bit more “cinema” when the lights go down, an LED TV backlight strip is a simple upgrade. The Daymeet TV LED Lights set is designed to sit behind your TV and add colourful ambient lighting, with options for preset scenes and music-driven effects.
That said, it’s not a one-size-fits-all gadget: where it lands best depends on your TV size (it’s aimed at 55–75 inch screens), how you plan to mount it, and whether you’ll actually use features like music sync through the app.
Key takeaways
Daymeet positions this as an RGB 5050 TV backlight strip with scene modes, plus an optional music sync mode. It also gives you multiple ways to control it: a 21-button remote, Bluetooth app control using the “duoCo Strip” app, and a small 3-button controller box on the USB cable.
For everyday use, the appeal is pretty straightforward: you can change the mood quickly (scene modes and colour effects), and you can also let the lights react to music using the built-in microphone. It’s the kind of product that can look great in a dark room without needing anything too technical.
The essentials
At a practical level, this is a 4M USB-powered LED strip that’s meant for TV ambient lighting—powered via a low-voltage 5V USB port for safer use compared with mains-style lighting. Installation is designed to be DIY: you peel off the double-sided tape and place the strip behind the TV.
In the spec details from the listing, you’re getting “over 21 dynamic modes” and “16 million color changes”. That’s a lot of choice for switching up the look, although in real terms you’ll likely stick to a handful of colours or modes you prefer.
There’s also a range of potential placements beyond TV—monitor setups, desks and shelves are mentioned—so if you’re the type who likes updating the look of a room for weekends, parties or holidays, it can pull double duty.
What to know about music sync
The music sync feature uses a high-sensitivity microphone. The idea is you enable microphone mode in the app, and the TV LED backlight colour changes automatically with the beat of music or even your voice.
It sounds fun (and it is, on paper), but it can be a mixed bag depending on your room. You may find it reacts best when the audio is clear and fairly loud, quieter tracks or muffled sound can lead to less dramatic changes. Also, because it’s microphone-based, background noise in the room can influence what it “hears”.
Where it shines (and where it might fall short)
This set looks like a good match if you want colourful ambient lighting behind a TV and you’d like options that don’t require complicated setup. The remote makes it easy to switch scenes without touching your phone, while the app adds more control if you want it.
On the flip side, LED strips like this are always limited by how much space you have behind the TV and how neatly the strip sits out of sight. The listing notes the receiver can be hidden behind the TV, which helps with aesthetics, but coverage and visual effect can depend quite a bit on your TV stand/placement and how straight you apply the tape.
Also, if you’re expecting “the most accurate, high-end sync experience” tied perfectly to your screen content, this listing doesn’t describe that type of advanced on-screen synchronisation—so it’s more about music-reactive mood than pixel-level precision.
Usage tips
A sensible way to get a decent result is to plan placement before you peel the tape. Clean and dry the surface so the adhesive has a good chance to hold, then apply the strip in a straight run behind the TV.
For a quick setup routine: after installation, start with one of the preset scene modes for the first test, then switch to music sync if you want the party effect. In practical terms, that’s handy when you’re deciding what you prefer—calm ambience for films, or reactive colours for games.
If you’re using Bluetooth app control, you’ll need to download the “duoCo Strip” app from Apple Store or Google Play and open it so Bluetooth can connect automatically. That’s a small step, but it’s part of the workflow.

Is it worth it?
Buying this Daymeet TV LED Light Strip makes sense if you want straightforward DIY TV ambient lighting with plenty of colour options, and you’ll actually use the remote or app rather than leaving everything on one setting. It’s especially appealing if you enjoy themed nights—games, festive moods, or music-driven lighting.
You may want to skip it if your priority is precise, screen-content syncing rather than mood-based lighting. It might also be a less satisfying choice if your TV installation space behind the set is tight, because the visual effect depends on how the strip can sit neatly out of sight.
Finally, do check the fit for your TV size (55–75 inch range is stated) and be realistic about what music sync can do when it relies on a microphone and room audio.
