with ceilings eleven feet to sixteen
feet in height, and these include prob.
ably ninety per cent of the factory
rooms in Wisconsin, he recommended
the one hundred watt tungsten lamp
with a fourteen or sixteen inch white
porcelain enameled steel, shallow bowl
reflector. These should be hung ten
feet from the floor and at twenty foot
centers. He emphasized the import
ance Of not necessarily arranging these
lamps uniformly over the room, but ar
ranging them with regard to the ma
chimes in the room. He stated that in
all industries such as woodworking
and paper industries where the work
is not fine work, individual machine
lighting can be done away with if the
above type of lamp and reflector are
located over the individual machines
as far as it is possible.
In rooms, such as warehouse rooms,
where the ceilings are nine to eleven
feet in height, the sixty watt lamp
should be used with twelve inch shall
lew bowl reflector.
In foundries the following lamps
were recommended for the height as
given as follows: Lamps hung under
20 feet from the floor, 200 watt; 20 to
25 feet from the floor, 800 watt; IS to
80 feet from the floor, 400 watt; 80 to
35 feet from the floor, 500 watt; IS to
40 feet from the floor, $50 watt; over
40 feet from the floor, 1000 watt.
A deep bowl reflector, seventeen
inches in diameter was recommended
for the $50 and 1000 watt lamps. A
fifteen inch deep bowl reflector was
recommended for the 300 and 400 and
500 watt lamps in foundries where the
width Of the foundry is less than
two and one-half times the height. In
wider foundries the shallow bowl re-
Electors were recommended on the
above lamps. In all foundries where
the 200 watt lamps are required the
shallow bowl reflector is recommended
Stairways should be lighted with 40
watt lamps, hung as high as possible at
the head of the stairways. A ten inch
bowl or cone reflector is recommended
For yards a 800 watt tungsten lamp
with a sixteen inch fiat disc reflector
is recommended These should be hung
twenty feet from the ground and from
two hundred to three hundred feet
apart.
For all individual machine lighting
Mr.. Price recommended % watt lamps.
1t has been found advantageous in
many cases, he said, to attach these
lamps to brackets or fixtures which
will hold the lamp in place. These
fixtures should be so constructed as to
make it possible to adjust the lamp.
The reflector should be so attached as
to completely hide the lamp from the
eyes Of the operator Individual lights
should be provided for all machines
on which fine work is done and suf-
fcient light should be furnished to
avoid eye strain.
A IS watt lamp with ten inch re-
flector was recommended for benches.
These lamps should be hung eighteen
inches above the bench and about
eighteen inches in from the front of
the bench. Where the work on
benches is not fine work the lamps
for general illumination will give suf-
fcient light.
For drafting stables 40 watt lamp
with a ten inch cone reflector or a
twelve inch bowl reflector, was recon-
mended. These lamps should be hung
about three and one-half feet above
the center of the table.
Mr.. Price stated that where rooms
are properly whitewashed it adds at
least twenty per cent to the efficiency
of the natural and artificial light. The
windows in the factory should be
cleaned regularly This increases the
efficiency of the daylight very much. -
