What are low voltage LED strip lights?

12V LED strip light is a low voltage lighting. The safe voltage that the human body can withstand is 36V. The voltage below 36V is called low voltage. Low voltage LED strip light has 5V, 12V, and 24V version. The most used are 12V and 24V.

International Electrotechnical Commission(IEC) defines the voltage below 120 DC as extra low voltage. So 12V and 24V LED strip lights are not only low voltage but extra low voltage, and can be used in a variety of occasions, posing no danger to the human body. This low voltage provides a super protection against electric shock and arc flash, creating an electrically safe condition for home, office, and commercial use.

Normally, short circuit with line voltage system is very dangerous and would cause sparks or loud explosions. But if you accidentally cause a short circuit with low voltage system, it would not cause any sparks or loud explosions. Therefore, any amateurs who want to try products such as LED strips can are very safe to do so.

Do you know why our human body's safe voltage is 36V? The reason why there is a safe voltage is that the human body is equivalent to a resistor, when a person touches a voltage, it generates a current, and it is the current passing through the human body that causes hurt to human.

Therefore, scientists have determined the maximum resistance of the human body under normal circumstances through experiments, and then obtained the human safe voltage value. This is why the human body safe voltage is 36V.

In summary, low voltage LED strip lights are very safe to use, posing no risk of electric shock or arc flash to human body.
