A portable LED curing light for dental applications includes a one-piece handle assembly with an angled light-producing end for positioning within a patient's mouth for curing a dental material. A replaceable lens for focusing light emitted by an LED light source is removably attached at the light-producing end. The handle also includes a battery and associated electronics for operating the light, including an operating switch, an audible indicator and at least one visual indicator. The handle is coupled with a base for storage and recharging, which positions the handle at an inclined position for draining moisture away from the handle. Circuitry in the handle monitors the status of battery voltage and handle temperature, and prevents operation of the switch from initiating a next curing cycle when battery voltage is determined to be too low or handle temperature is determined to be too high.
