An energy efficient fluorescent reflector lamp includes a fluorescent light source enclosed in a reflector with a defined cavity and circumferential rim defining a light emitting opening, and a circumferential flange at a mating opening. A housing has an interior surface defining a cylindrical opening. In the illustrative embodiment, the first mechanism is a master oscillator, the second mechanism is a phase conjugate mirror, and the system further includes a power amplifier positioned to amplify the first beam during a first pass and to amplify the second beam during a second pass. The method further includes searching a full motion video database based on the one or more search terms. The methods can use content vector analysis to determine the similarity between the essay and one or more prompts. The support layer includes polyurethane foam having channels aligned with the joints of the articulated sections of the foundation or frame of the adjustable bedding assembly.
