Power Necessary

157. While the list which we give herewith is based largely upon area, it may be taken as a basis of calculation for lighting equipment.

It is estimated that 300 square feet of a hallway requires four sixteen-candlepower, or eight eight-candlepower units.

In a room 20 x 20 feet, with furnishings of mahogany and green, broken up by bookcases and other furniture producing heavy shadows, it is estimated that twelve eight-candlepower lights are suffici

nt if worked into the frieze, and that a reading lamp of not less than thirty-two-candlepower be used as a drop light.

Assuming a room is 15 x 15 feet, and furnished in light tones, four eight-candlepower lamps are ample.

A living-room 20 x 25 feet, in light tones of color, requires two thirty-two-candlepower lights, centrally located, and about twelve eight-candlepower lights. This should provide brilliant illumination.

A room 15 x 20 feet, in dark wood and hangings, needs eight eight-candlepower reflector lamps, backed up by six more eight-candlepower lamps.

Bedrooms 15 x 15 feet in size, where they are not furnished in deep colors, should be equipped with two sixteen-candlepower lights.
