| description | An emergency lighting system including a light source, a variable constant current drive, an emergency alarm, and a controller. The light source includes a first light channel that produces light at a first correlated color temperature and a second light channel that produces light at a second correlated color temperature that is less than the first correlated color temperature. The variable constant current drive is configured to supply DC current to the first light channel and the second light channel. The emergency alarm is configured to be triggered upon detecting the presence of an emergency condition. The controller is configured to determine whether the emergency alarm is triggered, increase the DC current supplied to the first light channel when the emergency alarm is not triggered, and decrease the DC current supplied to the first light channel when the emergency alarm is triggered. |
