The X125 series are suitable for security, process control and light industrial applications where a lower cost and energy efficient solution is required. These beacons are of the flashing mode type (single stage alarm) Xenon beacons (sometimes called strobes) are controlled via a PCB and put out a very brief but bright flash of white light by ionizing and then discharging a large current through the xenon gas. The design allows for termination inside the enclosure through the base (except ES version). The ES version has an ES27 Edison Screw cap fitted into the base of the beacon. This design lends itself for use in temporary signalling locations where a warning or hazard is not normally present, or has the ability to be installed in an area using existing electrical lighting points, avoiding any additional wiring.
