The electronic lighting device includes an outer shell with a first opening at a top surface and a core contained within the outer shell. The core includes a left semicircular structure and a right semicircular structure arranged to form a circular shape that is aligned with the first opening at the top surface of the outer shell. The device includes a flame component positioned partially in the internal cavity. The device also includes a light emitting element disposed at least partially in a lighting element installation cradle on a sidewall of the core to hold the light emitting element at a non-zero angle with respect to a longitudinal axis of the electronic lighting device to allow illumination of the flame component. The device further includes a control circuit to control an operation of the lighting emitting element.

A method is for dynamically adjusting a circadian rhythm of an observer via a user device that includes control circuitry and an associated memory. The method includes accessing a calendar, identifying future events to precondition for and determining a preconditioning schedule for at least one of the identified future events. Determining the schedule includes identifying a circadian shift needed for the at least one identified future event, determining a magnitude of the circadian shift, determining a timeframe for preconditioning, determining a magnitude of a per-day shift based upon the timeframe, and determining if the per-day shift exceeds a maximum allowed per-day shift. Also, the method includes, upon a determination that the per-day shift exceeds the maximum allowed per-day shift, setting the preconditioning schedule responsive to the determination, establishing communication between the control circuitry and a light source, and operating the light source to emit light based upon the preconditioning schedule.

A solid state lamp includes a connector and a bulb portion with multiple strips.
