Voltage drop or 'drop volt' occurs in all types of electrical installations. When the larger power cable being installed more complex calculations to be done to resolve the issue. But when the LED strips or tapes are concerned there are some simple guidelines to follow.
Volt drop across the LED strip occurs when the LED is positioned too far from a power source or when more people walking (or rows) are attempted. This happens because not enough power or electric current reaches the LED, because it has further to travel. This causes a voltage decrease or drop towards the end of the run.

Volt drop can be compared to a person climbing a mountain, the higher the altitude, the oxygen becomes thinner and less people can breathe.
LED at the beginning of the line will appear bright at 100% output but towards the end of the line LED will begin to fade. brightness will decrease exponentially; much got away from a power source.
Volt drop in a single color strip looks barley, especially in short lengths. Color changing strip is visible when you turn white. If there is not enough tension towards the end of the strip clear white color will be pink towards the end of the line.
However, it requires less voltage than the red green and blue. When the strip away from the power supply, green and blue are not getting enough voltage and be weak, while the red color becomes more prominent and turns white to pink.
