Govee TV LED Backlight 2 cuttable to fit (RGBWIC) for 32–70 inch TVs with Matter, music sync and app control
Product description
If you want a more “alive” TV setup without going down the rabbit hole of complex wiring, this Govee TV LED Backlight 2 is built for exactly that. The cut-to-fit strip is designed to line up neatly around the back of your screen, and the one-piece snap mounting aims to keep installation fairly painless.
Still, it’s not a universal “stick it anywhere and forget it” product. There are some real-world limits around where you can cut the strip, and this model doesn’t include camera colour capture. So it’s more about ambience, colour effects and audio-reactive lighting than copying what the camera sees.
Key points
This backlight strip is for adding RGBWIC colour and a dedicated white channel behind your TV, with a cut-to-fit design intended to suit 32–70 inch screens (including sizes that don’t match perfectly straight edges). You get plenty of built-in scene modes, music syncing via app audio pickup, and smart control support that includes Matter alongside Alexa and Google Assistant.
On the practical side, the most convincing element is the setup approach: it’s a single strip with a snap-mount style, and the idea is to stick it along the TV’s back edge so it looks aligned rather than leaving gaps. If you’re after a clean “cinema vibe” look for films, games or music nights, that’s where it tends to make the most sense.
The essentials
The strip is described as a 4-in-1 LED setup with a dedicated white light, aimed at richer colours and smoother gradients compared with simpler single-colour systems. The product also mentions 30 LEDs/m for higher brightness and more consistent lighting coverage.
One more important detail: it does not have a camera colour capture function. That means it won’t track colours from the screen in the way some TV bias lights do, instead, it relies on programmed scenes and audio-reactive effects.
Key features
Cut-to-fit for TV sizes and less “weird corners”. The standout feature is that it’s cuttable to fit across different TV widths and even irregular shapes, with a goal of avoiding dark corners. In theory, that helps if your TV’s rear layout makes it hard to match a fixed-length strip.
Beginner-friendly installation (no complex wiring). It’s presented as a one-piece light strip with innovative snap mounting. The approach is “stick it along the TV back” rather than splicing segments together.
Lots of modes, plus music sync. You’re getting 210+ smart lighting scene modes, and the product also calls out 11 music sync modes. The music syncing works through the app using audio pickup, so it’s intended to react in real time to your TV sound or music soundtrack.
Smart control with voice support. It supports Matter with Alexa and Google Assistant, so you can manage lighting hands-free if you’ve already got a compatible smart home setup.
Please note before you cut
There’s a specific cutting limitation: the section between two scissor symbols on the light strip represents a complete circuit. You must only cut at (or slightly after) the marked scissor symbols. Cutting anywhere else can damage the circuit and stop that segment from lighting up.
What you’ll notice day to day
In use, this kind of TV backlight mainly changes the “feel” of viewing—especially in dim rooms—by adding a coloured glow behind the screen. For films and gaming, the combination of scene modes and a dedicated white channel can make transitions look more natural than a basic single-strip RGB setup.
A quick example of how you might enjoy it: start a gaming session, open the app, choose a dynamic scene, then enable music sync when you’ve got a soundtrack or party playlist on. Because it reacts to audio via the app, the lighting should respond as the music or movie sound changes—good for turning an ordinary evening into something more immersive.
That said, if your main goal is “screen-matching” colours using camera capture, you’ll likely feel limited. Since this model explicitly lacks camera colour capture, you may find it more like entertainment ambience than true screen replication.
Who it’s for (and who should be cautious)
It makes sense if you want a DIY-friendly TV backlight that you can tailor to your TV’s size, you like switching between many modes, and you’re happy using app/audio-based music sync rather than camera tracking.
It may not suit you if: - you were hoping for camera colour capture from what’s on the screen - you’re likely to cut the strip without carefully following the scissor marks (the circuit warning is genuine) - you want the easiest possible setup without any measuring/thinking first, because cut-to-fit still means you need to align it properly behind your TV

Final verdict

You may want to skip it if camera colour capture is a must-have for you, or if you’re not comfortable measuring and cutting only at the marked scissor symbols—getting that wrong can stop a segment from lighting.
