The pixels use 8mm diffused RGB LEDs, with a 120 degree beam width. The total max brightness of all

LEDs is about 1600mcd but with the light more evenly distributed & mixed than a clear LED. (Please note:

mcd ratings of LEDs are notoriously inflated by most LED sellers, so be extra-skeptical when reviewing

LED ratings!)

Sold by the strand, each strand has 25 pixels in series! Each strand has two JST SM 4-pin connectors so

you can connect multiple strands in a row, as many as you wish, just watch for how much current they

want. We now have LED pixel strands with the power wires (red & blue) spliced out so its really easy to

connect 5VDC in using a 2.1mm jack terminal adapter. We have a 5V/2A supply that should be able to

drive 2 or more strands and a 5V/10A supply that can drive up to 160 LEDs all lit up at once

If you want to connect to the strand (to wire it to power and a microcontroller), you could cut and solder to

the wires, but better yet just grab a 4-JST cable set - then check the LED modules to see which way is the

input (there's arrows showing the data direction)

You can drive these with an Arduino using any two microcontroller digital pins, check this library which

also has example code to demonstrate the strands and be sure to read our very detailed tutorial on

usage! https://github.com/adafruit/Adafruit-WS2801-Library http://www.ladyada.net/products/rgbledpixel/
