Because they run on low voltage dc they require a power supply device that converts 120v 240v ac depending on your location into the voltage signal that led strips can use.
Using computer power supply for led lights.
The power supply also known as a transformer or driver is one of the most important components of an led system.

The c 3 led device or assembly includes reversed opposing die or leds with an integrated or on board matching capacitor.
A lot of power supplies such as mean well products will be rated for the full range but it is always helpful to know your ac input and make sure that the power supply you use is suited for this.

Led strips unfortunately are not as simple as traditional incandescent light bulbs when it comes to installation and set up.
Compared with using the same die in a dc driven resistor based circuit the c 3 led approach can provide higher brightness at the same power or alternatively uses lower power at the same brightness depending on the device or system design.
Batteries also output dc power so it is easy to make a battery powered led light with these flex strips.
Make sure you know whether you have low line ac power 90 120vac or high line ac power 200 240vac.
It is also important to know your input ac voltage and be certain that it coheres with the products.
