== What are LED Strips? ==
The idea with the LED Retrofit is to provide the HS with an effective yet sleek lighting solution, by using color-changeable LED strips which are controllable via the network.
Here is an exhaustive explanation and tutorial from [http://www.ladyada.net/products/rgbledstrip/ laydyada]. In essence, there are 3 SMD (Surface Mount Technology) RGB (Red Green Blue) LEDs (Light Emitting Diodes) on a segment with 3 resistors which allow the ~3 v LEDs to be drivven using a 12v power supply. These 'segments' are continuously joined together to form spools 5 meters each. Sometimes you can buy them in smaller bits (1 meter, 50 cm, 1 foot, etc), but sticking to a 5 meter spool is the best.
