Abstract
A permanently-installable LED light fixture including a housing including a substantially water-tight chamber, at least one electronic normal-operation LED-driver enclosed within the chamber and receiving power from a general off-location power source during normal operation, an LED assembly secured with respect to the housing, the LED assembly having at least one LED-array module, and at least one backup battery within the chamber capable of providing power during a power outage. In certain preferred embodiments at least one electronic backup LED-driver unit is enclosed within the chamber, the backup LED-driver unit drawing battery power during a power outage.
