What I find very good: It does not matter how many bars you use, you must not take all. Since I did not want any lights below, handed me above 3x30 cm and at the sides of each 1x40 cm (47 inches). So I have 3 bars left as a substitute.
I have the strips mounted directly behind the edge of the TV is now about 20 cm from the wall - the backlight is perfect, no light cone, everything illuminated beautiful uniform.
The light in warm white is more yellowish, but that's ok like this.
Conclusion: Very good LED strips at a good price, Easily assembled and to install and good uniform luminosity.
I recommend the variant L (42-60 inches, 107-152 cm) to buy. Even if you have a smaller TV, it's in the price relatively cheaper, because then you have still the same bars as a substitute left.
