A low-power illumination system for use with an associated barrier operator, or independently, comprises at least one illumination unit adapted to be operable via mains power and a backup power supply, such as a battery. Accordingly, if mains power fails, a low-power light element maintained by the illumination unit may be responsively powered by the backup power supply to provide backup lighting. Alternatively, the barrier operator may be configured to detect a mains power failure, such that when such failure is detected, an illumination command signal also needs sent to the at least one associated illumination unit causing for it to be illuminated.
