Abstract
A light assembly coupled to a spray gun for spraying electrostatically charged coating material is disclosed. The spray gun includes a gun body comprising a barrel, a nozzle assembly extending from the barrel in a longitudinal direction, a voltage multiplier, and an actuator assembly configured to transition the voltage multiplier between an activated state and a deactivated state. The light assembly includes a light and circuitry electrically connected to the light. The circuitry is configured to supply electrical energy inductively obtained by the circuitry to the light when the voltage multiplier is in the activated state. The light assembly can also include a housing, a lens cover releasably attached to the housing, and a control member for changing a characteristic of the light.
