A wireless local area network system comprises a 5. Top and bottom frame ends of the body are interconnected by a flexible wall structure that undergoes deformation in response to movement of one frame end relative to the other. One cycle comprises introducing a pulse of a first precursor, introducing a pulse of a second precursor, and introducing a pulse of a third precursor in which the pulse of the second precursor and the pulse of the third precursor at least partially overlap. A lighting control input means, associated with the bezel allows adjustment of the intensity of light emitted by the light source.
