1. A lighting apparatus configured as an N by M array of headlamp modules, the apparatus comprising:
a low beam headlamp module comprising:
a first blue light source device having a first predetermined output power, and comprising a gallium and nitrogen containing material configured to emit electromagnetic radiation having a wavelength ranging from about 400 nm to about 500 nm and having a first beam spot size with a first blue light source output beam;
a first phosphor material configured to interact with first the blue light source output beam of the first blue light source device to generate a first white light output of electromagnetic radiation characterized by an output of 400 lumens to 2500 lumens and 500 Candela per square millimeter and greater;
a first surface mount substrate configuring to attach the first blue light source device on a surface of the first surface mount substrate;
a first lens device operably coupled to the first white light output to focus and spread the first white light output to cause formation of a low beam white light;
a high beam headlamp module, different from the low beam headlamp module, comprising:
a second blue light source device having a second predetermined output power, and comprising a gallium and nitrogen containing material configured to emit electromagnetic radiation having a wavelength ranging from about 400 nm to about 500 nm and having a second beam spot size with a second blue light source output beam;
a second phosphor material configured to interact with second the blue light source output beam of the second blue light source device to generate a second white light output of electromagnetic radiation characterized by an output of 400 lumens to 2500 lumens and 500 Candela per square millimeter and greater;
a second surface mount substrate configuring to attach the second blue light source device on a surface of the second surface mount substrate; and
a second lens device, different from the first lens device, having a total internal reflection (TIR) element operably coupled to the second white light output to focus and spread the second white light output to cause formation of a high beam white light.
