A solid-state lighting device for use in lieu of a gas discharge lamp, includes a housing; a lens coupled to the housing; a circuit board; and a plurality of solid-state light emitters carried by the circuit board and arranged to generate light to pass through the lens. An entirety of a form factor of the solid-state lighting device may be located within a cylindrical envelope having a length less than or about equal to an overall length of the gas discharge lamp and a diameter less than or about equal to the overall diameter of the gas discharge lamp. In addition, a light center length of the solid-state lighting device may be about equal to the light center length of the gas discharge lamp. Solid-state light emitters are arrayed with principal axes of emission radially spaced at least partially around and extending from a central axis of the lens.
