B.The portable light fixtures are those movable ones like table lamps, desk lamps and standard lamps. The standard lamps and traditional lamps emit diffused light while the desk lights emit light directed straight to the working area. The desk lamps save space because they come with a stand or clip-on fixing. Examples of portable lights are table lamps, hi-desk lamps, standard lamps, adjustable desk lamps and wall lights.

Wall lights are controlled with a dimmer switch and mostly used in dark rooms to illuminate dark areas and halls. These fixtures cast a diffused light. The modern wall fixtures radiate a concentrated light which can be directed to a table, chair or used to highlight a decorative plants or pictures or posters. The different kinds of wall lights are bulkhead light, cone-shaped wall light and imitation gas light.

C. Spotlights illuminate directional light in medium, narrow and wide beams. These type of light fixtures can be mounted to a ceiling or recessed for flexibility. They can also be fixed to a clamp on desks, bookshelves or clipped into a wall as lighting tracks. Examples of spotlights are general purpose spotlight, low-illumination spotlight, cowled spotlight and uplighter and downlighter spotlights.

Downlighters are used to radiate light to a lower level from the ceiling. These fixtures are cylindrical and squares. They can be installed fully in a hollow into the ceiling or mounted into the surface of the ceiling. Narrow uplighters and downlighters highlight a certain area while the wide light kind gives more light. The uplighters are fitted opposite giving light up into the ceiling.
