LED strip lighting questions

Here is a copy and paste from one of my posts:

Here is a closeup of the strip. Notice that each set of 3 leds are in series with each other and a current limiting resistor. On the top and bottom of the strip there are the + and - buss. at each end there are copper solder pads. This strip can be cut to any length as it is configured in a series-parallel connetion.
