SAVE:US is an emergency downlight system for buildings that enables rapid evacuation and rescue activity when a natural disaster strikes.

When natural disasters such as earthquakes and typhoons occur, the rapid evacuation and rescue of people is a top priority. Products that assist this aim are of critical importance. Rapid evacuation becomes difficult when the electrical supply to a building is cut, as those trapped inside may have difficulty locating the evacuation routes and exits in the dark.

During normal conditions, SAVE:US takes the appearance of a regular downlight. In an emergency situation, a flashlight with an embedded GPS module drops down like an oxygen mask in an aeroplane. The emergency light is charged by standby power during non-emergency times, and thus is always ready to use. Due to the presence of the GPS module inside the emergency flashlight, the location of an evacuee can be easily deciphered by the rescue team.
