144/m APA102 Addressable RGB LED strip, 1m, 5V
There are 144 LEDs in total, and each strip is sold in a 1 meter long length. Each strip can be easily cut, or can be 'daisy chained' with other strips in order to produce long chains of LEDs. At the ends of the strips are male/female 4 pin JST-SM plugs which allow multiple strips to be connected.

This flexible RGB LED strip uses the newer APA102C LED chips instead of the older WS2801 chips. The APA102C chips are easier to control and offer faster (20kHz) PWM rates for flicker free performance. This strip comes with white PCB.
Each LED on the strip is 5050 size, and has an embedded microcontroller inside it which controls brightness levels, and interprets the data you send it. Each strip needs two wires to control all LEDs, one clock and one data. This arrangement makes it easier to use with slower devices like the Arduino Uno.
Power supply to the strip is 5V. It's wise to consider that each LED can consume around 60mA at full brightness - multiply that by 144 (per meter) and you have over 8.6A, or about 43W of power dissipation.
