[Cellar]
In installing lamps for the cellar the time they are lighted should be borne in mind. As this is short, the expense of running larger lamps—25 watt and 40 watt—is insignificant. The following locations should be provided for:
Bottom of cellar stairs 25 watt
Work bench 40 watt
Laundry 40 watt
Vegetable and fruit cellar 25 watt
Lamp in front of furnace 60 watt
This latter lamp is usually close enough to also illuminate the coal bin.
[Care of Lamps and Fixtures]
Lamps and fixtures should he cleaned once a month to insure the maximum efficiency. Reliable tests have shown that dirty glassware reduces effective illumination from 10 to 50 per cent.
