ABSTRACT:
An improved image projection lighting device is disclosed. Commands received by a communications port of the base housing may be acted upon to change zoom and focus values of a zoom and focus lens. A cooling system may be provided which compares an input air temperature of the image projection lighting device to an exiting air temperature to determine if a filter needs service. A video projector may project a first image comprised of first, second, and third separate images and the first separate image can be faded up to project light that is void of an image by a first command received at the communications port.
