Abstract

The claimed subject matter provides systems and/or methods that facilitate remotely controlling a wireless lighting module. The wireless lighting module can include a power source such as a battery, a solar cell, and the like as well as an array of light emitting diodes (LEDs). The LEDs can be controlled based upon a received input (e.g., communicated by way of a radio frequency signal, an infrared signal, . . . ). For example, the input can be obtained from a remote control, a sensor, a differing wireless lighting module, an radio frequency identification (RFID) tag, and so forth. The input can be utilized to switch one or more LEDs on or off, change the intensity or color of illumination, modulate illumination, alter the direction of illumination, etc.
