Aspects of the presently disclosed embodiments may include a wireless power outage lighting system comprising one or more power change detection apparatuses and one or more wireless lighting modules where the system is implemented to allow management of multiple groups in the same area such that interference may be avoided when there are multiple transmissions in the same area. A power change detection apparatus may be configured to transmit to avoid interference with another power change detection apparatus. A power change detection apparatus may also be configured through the user input method to operate different groups of wireless lighting modules such that lighting zones may be created. Multiple lighting zone allow a user to configure lighting provided by the wireless power outage lighting system based on their preference.
