Example embodiments of the present invention described herein generally relate to an LED lamp or LED lighting device wherein the operating light aspects or qualities (e.g., brightness, color temperature, CRI, and/or the like of the light emitted by the LED lamp or LED lighting device when the LED lamp or LED lighting device is being operated and/or is turned on), is selectively configurable. For example, example embodiments of the present invention described herein generally relate to an LED lamp or LED lighting device wherein the operating color temperature (e.g., the color temperature of the light emitted by the LED lamp or LED lighting device when the LED lamp or LED lighting device is being operated and/or is turned on), is selectively configurable. However, it should be understood that principles of the present invention may be used to provide an LED lamp or LED lighting device for which one or more aspects or qualities of the light provided during operation of the LED lamp or LED lighting device may be modified through selection of a particular mode. Examples of the aspects that may be modified through mode selection may include, but are not limited to, brightness, CRI, color temperature, and/or combinations thereof.
