in order to save the installation cost and time ,we produced the led flexible strips under the 100--240v working without using extra power supply like old type DC 12 /24V driving methods.
the desirable features that we can connect the strips longer up to 100 meters one time ,so this will save your installation cost and installation process .
the color is red blue green yellow warm white cold white and RGB with smd3528 or smd5050 leds
