Beginning with suitably placed shaded wall brackets that serve best for coloured high-lights when the hostess employs table candles, one may change the room atmosphere by adding the ceiling unit capable of producing a strong and fairly concentrated downward beam of light intended to cover the table top and to brightly emphasize the centre of interest. The arrange ment suggests at least two separate circuits whereby the central ceiling unit may be turned off at will or reduced in intensity be tween actual meal times. The modern touch is added through the incorporation in the central ceiling unit of a very narrow beam spot-light to concentrate upon a central table decoration. The floor outlet beneath the table permits the convenient attachment of the table cooking appliances or the luminous ornament, includ ing electric candles. In the dining-room the chief secondary centre of interest will be the corner cabinet or sideboard wherein the usual glassware and china form interesting patterns and shadows when lighted from concealed tubular sources around the tops and edges. In general the pure white light will best emphasize the silver and the linen but there is the added charm at breakfast time or at the end of the meal that results from a lowered intensity and a shift from strong white light to the glow of the flame tint colours. In larger rooms the plaster or metal coves some 18 inches to 24 inches from the ceiling can serve this usage but must be planned on the basis of decoration rather than efficiency and to provide a uniform distribution with tubular lamps with a power consumption on the order of 25 watts per running foot.
Here the necessity of a good work light sug gests the diffusing globe at the centre of the ceiling with a 75 to 150 watt lamp supplemented by a 25 or 4o watt shaded bracket light above the sink, and in a larger room a similar local light over the stove. Any semi-indirect bowls or basins are liable to collect dust and increase the maintenance difficulties. The fired enamel finish on all metal parts or the glass and porcelain fixtures are preferable. For convenience there should be the small lamp within deep shelving or in the closet, and the duplicate switching control permitting at least one kitchen light to be turned on re gardless of the door through which the person first enters.
Every normal bedroom should have a central ceiling fixture, preferably of the dense or low bright ness semi-indirect bowl type, or a completely indirect unit, to supply uncoloured general illumination in the range of 3 to 5 f oot candles, sufficient for dressing but not in itself enough for con tinuous reading or toilet preparations. For the sake of the comfort
of the person in bed, this ceiling unit should never be visibly bright and should be controlled from both the main entrance door way and from a switch beside the bed. The warmer tinted table. lamp of sufficient height for reading, or preferably the wall or bedstead unit some 3 feet above the pillow, will be an added convenience. A pair of vanity portable lamps, preferably of not less than 4o watts each, will serve at a dressing-table, or if space be limited then a pendant or bracket unit at the left-hand position when facing the mirror. Beneath the bed and especially for sick room emergencies, there should be at least one twin outlet and at such a position may be plugged in the small wattage night light at base-board level. Around the oft-used mirror, and espe cially in the bathroom, should be a diffusing and continuous trough or line source to flood the face from all directions and yet not brightly glaring. In the bathroom the small wattage ceiling globe provides a good work light but will not suffice for shaving nor is the exposed frosted lamp bulb recommended by the side of the shaving mirror. Each clothes-closet should have its lamp mounted where it will not be in contact with fabrics. Often any lighting unit as in closets, basements or attics that may be forgotten and left burning will be noticed if it is connected with a small luminous indicating bull's-eye on the switch or beside the door. Also as a burglar alarm or in emergencies, there should be several units around the halls and main rooms that can be turned on from a master switch beside the bed and independent of other switch control. Where children play or read there must be especially well-shaded light, the same applying to sewing rooms and for aged persons. The indirect wall bracket over the child's crib acts as a protection against glare and serves to floodlight the entire space. Avoid carefully any switch or pullchain sockets in bathrooms as electric shock under these conditions becomes extremely serious. The approved student reading lamp is the best portable work light, or an adjustable shaded bridge lamp suffices for the writing desk or the sewing table.
