Excellent "Bars" lighting with very good brightness and beautiful design for placement both in a visible spot and in a hidden one.
Personally, I placed it behind a 65-inch television from left to right and I can say that the brightness is sufficient even for a 65-inch TV.
Through the Philips Hue Bridge and the free Philips Hue application, you unlock millions of colors and scenarios.
A. For mobile, the main free application is Philips Hue, which requires you to have the Philips Hue Bridge to fully utilize the Hue lighting.
There are also other notable third-party applications such as:
1. Hue Essentials (Costs about 6 euros and if you don't use the Philips Hue Play HDMI Sync Box, it is a good solution to synchronize your mobile with your Hue lights for image and music).
2. Huegasm (Costs about 5 euros and is a music-only application, but it is worth more than the Hue Essentials application due to better light settings.
Personally, I use both, the first one for movies and YouTube, and the second one for music, and I am fully satisfied with my mobile experience.
B. For the laptop, there is the free Hue Sync application from Philips, with which you can synchronize:
1. Scenes
2. Games
3. Music
4. Video
This specific application fully covered my needs for the laptop and I didn't need to pay for any extra application.
C. For the television, it is necessary to have the Philips Hue Bridge and the Philips Hue Play HDMI Sync Box, or by connecting the television with at least Version 2 HDMI (for better response), you can synchronize your Hue lighting with the television through the free Hue Sync application on the laptop.
In the box (Unbelievable packaging, well taken care of), you will find:
1. Two bars with a long integrated cable in each one separately.
2. The charger, which can accommodate up to 3 bars (Convenient for purchasing a third bar for placement on the back or top of the television).
3. Two sets of brackets with their screws and double-sided adhesive tape.
a. The first set of brackets is for placement with double-sided adhesive tape behind the television.
b. The second set of brackets is for supporting the bars vertically or horizontally in the desired spot.
I already own:
1. Philips Hue Bridge
2. Philips Hue Smart Dimmer Switch
3. Philips Hue White And Color Ambiance Single Bulb E27
4. Philips Hue White and Color Ambiance Play Light Bar 2-pack
5. Philips Hue Smart Lightstrip 2m White and Color Ambiance Plus base pack
All of the above lighting devices will be reviewed, so if you're interested, visit each one and get informed.

Initially purchased (3 pieces) for ampilight lighting in combination with HUE BRIDGE, HDMI SYNC on a 65'' television.
In practice, it left gaps possibly due to the size of the television, but after placing the led strip, they were placed as supplementary lighting at the base of the furniture with impressive results.
They synchronize very easily with the bridge in a Homekit environment.
Up to 3 bars (2+1) do not require an extra socket.
If you want them to work as light effects according to the content of the television, computer, music, the bridge and the HDMI sync are needed.
The price is a negative aspect.
