System and method for controlling a group of lighting modules

A system for controlling a group of lighting units, the system including a narrow-beam infrared remote control unit configured for communicating a first control signal to a first lighting unit of the group of lighting units via an infrared frequency communication link, wherein the first lighting unit is configured to:

• (a) perform an operational mode in response to the received first control signal;
• and
• (b) communicate a second control signal from the first lighting unit to at least a second lighting unit of the group of lighting units via a first radio frequency communication link whereby said second lighting unit is configured to perform an operational mode in response to the received second control signal;
• wherein a radio frequency remote control unit is configured for communicating with the first lighting unit and the second lighting units via a second radio frequency communication link so as to define the first lighting unit and the second lighting unit as part of the group of lighting units.
