A lighting device is arranged to receive or determine information indicative of geospatial location (and optionally additional information such as time, time zone, and/or date) and automatically adjust one or more light output parameters (e.g., luminous flux, color point, color temperature, spectral content, and operating time) based on such information to operate one or more emitters differently on different days of a year. Information indicative of geospatial location may be received or provided by a user input element, a signal receiver, and/or at least one sensor. Brightness and/or spectral content of lighting device emissions may be further adjusted intraday based on sensed ambient conditions, conditions of an illuminated space or surface, information indicative of weather conditions, and/or user inputs.
