Lamp with variable flickering frequency

A lamp for generating flickering at a selectable frequency corresponding to a desired human brainwave state, comprising:

• a base;
• a light source supported by the base;
• a shade having a plurality of regularly circumferentially spaced apertures defined therein;
• the shade circumferentially surrounding the light source and rotatably supported by the base for rotation about the light source;
• a drive mechanism supported by the base and drivingly coupled to the shade for rotating the shade about the light source;
• the drive mechanism and the light source coupled to at least one power connector for supplying power to the drive mechanism and the light source;
• wherein rotation of the shade while the light source is emitting light produces flickering for an observer looking at the lamp from a fixed position;
• the lamp further comprising at least one speed control coupled to the drive mechanism for controlling the drive mechanism to select a rotational speed of the shade to selectively produce one of at least:
• flickering within a first predetermined frequency range corresponding to a first pre-selected human brainwave state;
• and
• flickering within a second predetermined frequency range corresponding to a second pre-selected human brainwave state;
• the first and second pre-selected human brainwave states being different from one another.
