The invention is a light that operates in many different modes based on a settings switch and environmental conditions such as ambient light levels and the detection of movement near the light. In one of the modes, the light will only come on after a darkness threshold has been reached and movement is detected near the light. By limiting when the light is on maximizes the amount of time the light can operate without recharging the energy storage unit. In another mode, the light comes on when there is movement detected near the light regardless of the darkness threshold conditions. A walk-in closet light is an example of this type of light use. In all modes the light will operate for multiple days without power being available to recharge the energy storage unit. In each mode, the light brightness is determined by the brightness control. Lowering the brightness will increase the time the light will operate without an external power source to recharge the energy storage unit.
