5 m
The simplest and least fragmented version is the connection of material up to 5 meters long. In this case, you can do without an amplifier and an additional power supply for 12V.All you need is 1 PS of suitable power, RGB controller and LED material itself. So, the connection scheme for a multicolor ribbon of 5 meters looks like this: 
This option is rarely used due to the small length of the conductor. It is recommended to use it if you need to carry out original lighting on the balcony.
10 m
This length will be enough to illuminate the perimeter of a small room, for example, a corridor. If the power of the tape is not too large, you can connect two devices in parallel to one power supply and the controller. The main thing is that the power of the latter is higher than that of the two lamps. To your attention the connection scheme of RGB LED strip up to 10 meters:
If you bought a powerful tape( more than 60 led per meter), you will have to mount to an amplifier and an additional power supply. In this case, the project will look like this: 
15 m
With this length of material, you can not do without an additional RGB amplifier and power supply. It is recommended to choose devices of high enough power that they would be enough for the maintenance of two segments. Typical scheme of connecting RGB LED strip not more than 15 meters is as follows: 
This length will be enough to create a hidden ceiling lighting or lighting installation in the kitchen.
20 m
Well, the last, the most difficult option - the connection of multi-color tape, up to 20 meters. Here we recommend using the following connection scheme, with two power supplies and an amplifier: 
If you correctly select the power parameter for all the constituent elements of the circuit, the backlight will work for a long time and without any problems! If the length of the materials is even greater( 30, 35 meters, etc.), you need to act in the same spirit - add amplifiers and BP.You can see the connection process in the video below:
Here are all the most popular schemes for connecting an RGB tape with an amplifier and a controller to the 220 V network! Choose the most suitable option and proceed to connecting the wires. There is nothing complicated in the installation works, as you can see from the article, to which we referred at the very beginning!
