Most lighting books differentiate between task lighting, general lighting, and accent lighting. For example, a kitchen needs bright lighting over the food prep areas and at the desk but less lighting is appropriate at the table. And that flower vase will look dramatic with a recessed M-16 pinpoint halogen spotlight directed down to it.      Lighting plans are more complicated now, with xenon and halogen bulbs to compliment the incandescent bulbs.  Even incandescent bulbs came in a variety of shapes and sizes. Recessed lights are still appropriate, however, especially with dimmers to adjust light levels. Recessed lights with white baffles put out a lot more light than those with black baffles if you install basic bulbs. PAR lamps work best for directing light down out of the ceiling in recessed fixtures. Options for recessed lights are numerous, so go to the lighting showroom that offers a demonstration area.       Track lights have evolved into art forms in recent years. New tracks resemble flat two inch bands that can be curved to fit a wall or formed into an S-curve for fun. The track light "heads" have become designer features unlike the white cylinders of past. Avoid track lights that point at you—the glare can be miserable.       Low-voltage lights can be placed inside cabinets, inside ceiling trays, above crown molding, and under kitchen wall cabinets. Low-voltage lights require a transformer to step down the 110 voltage, but one transformer can serve several lamps.        Uplights from the floor or above cabinets or on top of beams will spice up a dreary room. Look for ways to light up your favorite artwork. Look for light fixtures in lighting showroom catalogs rather than at home supply centers, and you will find some exciting designs to compliment your remodeled rooms.       Most lighting design is uncomplicated, but teaming up with a good lighting designer will improve your end result every time.
