Practical test of the Govee TV Backlight 3 Lite - simple and effective LED lighting for your TV

Are you looking for a simple to run but effective LED strip for TV mounting? I've got something for you - treat yourself to a report on the installation, setup, calibration and month of using the LED light Govee TV Backlight 3 Lite tested on a 42-inch TV.

What you need to know to get started
The LED lighting presented here helps to significantly enhance the home cinema experience - a coloured LED strip is mounted on the back of the TV and dynamically adjusts the colours to match what is being displayed on the screen. This is determined by a camera mounted on top of the TV, so the whole thing does not occupy HDMI slots or require compatibility with a particular signal type and resolution.
How does the device know which LED is where? This is done by calibration - a very simple process, simply by first determining the orientation of the LEDs and then temporarily placing calibration dots on the screen.
What else can the device show? First of all, we have remote control via an app, the ability to create your own effects, compatibility with Alexa voice control, Google Home, and the modern Matter protocol.
In addition, the product shown here can work with other lights, further improving the effect.

Set contents
In our case, we tested the set for a 40-50 inch TV, although there are separate sets on sale for larger TVs too. When purchasing, it is important to note which version you will need. They differ in the length of the LED strips.

.

In the kit we receive an LED strip (or more precisely four strips connected together, just in time for our TV), a 12V 2A power supply, a main controller with three buttons, a cable for connection, a camera (for examining the image), instructions and warranty card, isopropyl alcohol wipes (to clean the surface before installation), extra clips to grip the strip and orange calibration cubes.



.



Mounting .
First you need to lay the TV safely on the screen - this must necessarily be on a flat surface, otherwise you risk damaging the matrix.

.

Then the LED strip can be glued on. Before sticking it on, clean the surface with the wipes from the kit:

.

The LED strip is on double-sided tape, just remove the foil from it.
When fitting the strap, you can additionally help yourself with the hooks from the kit - these too have a piece of double-sided tape and stick to the plastic.

.

Someone here might ask - which side to stick the strip on? It doesn't matter - later on in the configuration stage, the strip will simply highlight the two edges with the appropriate colours, and we can choose the matching configuration.
At this stage you can already check that everything works:

.

The camera must be mounted so that its foot holds a right angle to the TV screen:

.



Application and calibration .
We download the Govee Home app from the relevant shop (on Android it's Google Play, on iOS it's the AppStore):

.

You then need to set up an account, but this is not a problem - you just need to have an email address, no phone number. I tried to pair the device without an account, but although the hardware was detected, the pairing would not go any further.

.

We enable Bluetooth, WiFi. We allow the application to access.

.

The application will detect the new device itself:

.

The whole pairing process is an afterthought - you have to confirm it by pressing a physical button on the device, so your neighbour can't 'pick up' our equipment.



You will also need to enter the name and password of our WiFi - the 2.4 GHz standard is supported.



The pairing screen also shows us general instructions - you can't even go wrong here:



I mentioned at the beginning that the orientation (order of overlap) of the bar doesn't matter - oh well, here's an explanation of how it works. The app highlights two segments and we choose which edges of the screen they are mounted on:

.

The second part of the calibration is to stick the orange calibration blocks on the screen. We proceed gently, without pressing. The TV must be switched off, while the light in the room must be on so that the camera can recognise these blocks.

.

I was sure it would be a bit of fun with this - but nothing could be further from the truth!



Calibration is very simple. Simply adjust (drag) the virtual points to those set on the screen. In practice, there isn't even much of this adjustment - with me, the default setting almost perfectly matched already. In addition, we have a preview of the camera view, which makes everything even easier.


Practical tests .
To start with something simple - the colour test. Just search on Youtube for a suitable video. This is also useful for colour calibration - more on that later.

.

Now for something better - the animation of the 'fireflies', you can very well see how the bar instantly reacts and adjusts its colours to what is happening on the screen:

.

Now a longer test - more colours:

.

Tests with sample video:

Colour calibration .
The device also allows you to adjust the colours to what we have displayed on the screen. Calibration is available from the mobile app, after entering additional options. Personally, I didn't need to use it, as the results are very good even without calibration.

.


Custom animations .
The strip can also act as an ordinary LED strip. We can set predefined colours, play animations, and there is also a music mode (animation to the rhythm of music) and an animation configurator where we choose the LEDs and their colours ourselves.

.

Example effects:

.

Example of a custom animation - a white strip with several LEDs in red and green:

.

Same animation in the video - you can see the green and red. The rest is white light, although in my case a little bit of the colour of the furniture interferes with that.




Multi-device synchronisation - DreamView effect .
The device also supports the Govee DreamView system that allows external lights to be synchronised with the LED strip discussed here. Simply add another device to the app and then select it in the Synchronisation Centre.




Support Matter .
In the options, too, you can find the QR code needed to pair the device with the Matter. This allows you to make it available on Amazon Alexa/Google Home/Apple HomeKit. Detailed instructions can be found in the screenshots below.

.

Four-colour diodes .
It is also worth noting the construction of the LED strip shown here. This is not a normal RGB like the WS2812 - here we have RGBW LEDs, meaning that in addition to the basic colours (red, green, blue) we also have a separate white. This allows for much better colour reproduction and improves the visual experience.

Power consumption measurements .
Finally, a brief measurement - how much does it cost us to use such a belt? I show separately the maximum power I was able to record (cold white - the whole strip) and the standby power:

.

The actual output during normal use is much lower, as only LEDs of one or two colours are usually lit.

Presentation of effects and commentary - Youtube .
We also invite you to read a summary of the material on our YouTube channel:

Summary .
It's been a good month since I installed these lights on our TV. In that time we've managed to spend a few weekends watching and I can say in good conscience that the effect is really good. The colours are reproduced surprisingly well and the light from the LEDs blends in well with the background behind the TV, although in our case it would have been useful to move the cabinet back a little.
The installation, initial commissioning and calibration of this product also surprised me - I thought it would be more difficult. Basically, it didn't need much tweaking. I think anyone can handle it without any problems.
In addition, I liked the fact that the manufacturer has thought of everything - there are even physical buttons for people who don't like mobile apps. What's more, the product itself correctly turns off the LEDs when the TV is off, so it's basically maintenance-free.
It should also not be forgotten that the stripe used here is more than just plain RGB - the LEDs used have an additional separate white channel, which allows even better colour reproduction.
All in all, this backlighting will effectively liven up any living room or TV.
