The Glenwood post., 1911-08-19
Town Lighting By Mythical Company
Proves a Huge Farce Aldermen
Express Their Disgust
MAYOR TAKES BULL BY HORNS

from the fact that the Mutual company
ask 81 a month for 60 candle power
lamps with minimum of $50 lamps IN
stalled, or $500 for 5000 candle power,
while the Glenwood Light and Water
company charges $2s5 for $3.50 candle
power, or per cent less money for
more than five times the light.
Cost, however, is not the only thing
to be considered, and we shall now
compare the two illuminants in ques-
tion.
In the case of the tungsten incandes
cent lamp the light, after it has been
installed a few weeks, generally de.
creases, due mostly to gradual black
ening of the inside of the globe All
who have used the tungsten lamp are
familiar with this characteristic
Another feature of the tungsten incan-
descent lamp is that the light given
is practically uniform all around the
lamp, the result being that the illumini-
alton is maximum right under the
lamp, but decreases very rapidly as the
distance from the lamp increases. For
instance, 10 feet away from the lamp
the lluminatioa will be four times less
than five feet away. At twenty feet
it will be sixteen times less than five
feet; at forty feet, 60 times less, etc.
In addition to the above must be
considered the question of a system in
which the unit would be so small that,
in order to give enough light. several
of them would have to be installed in
each block with corresponding poles to
support them and wire to feed them.
Another point to bear in mind is the
difference in the look of the town at
night when lighted with only 5000
candle power after having enjoyed for
many years an amount of light of
$3.50 candle power.
Coming back now to the arc lamp
system, the light of it is maximum at
an angle of 40 degrees from the hor'-
zontal. This feature is most desirable
for street lighting, since candle power
near the lamp is less and INCREASES
as the distance from the lamp increases,
thus making the illumination, or the
amount of light thrown on the street,
much more uniform than an incandes
cent lamp could make it. The arc
lamps are kept in repair and trimmed
every day at the expense of the Glen
wood Light and Water company, and
this daily inspection keeps the lamp to
its full candle power night after night
and year after year.
If, as is probable, the Glenwood
Light and Water company, taking ad-
vantage of the development of cleo
trical science, decides to install, at con-
siderable cost, their new proposed sys-
tenn of magnetic lamps similar TO sys-
tens installed very extensively in the
city of Denver and most other large
cities, the efficiency figures mentioned
will be greatly increased, making the

} power per month, as compared with the
proposed tungsten system, still greater.
The RESUME OF COMPARISON Of
the two systems from which each per
! son may draw his own conclusions is
then as follows:
: Proposed Tungsten System: -. ....
, 5000 candle power installed for $500
. a month.
, Present Arc 8ystem:
$3.50 candle power for $2s5 a
. month.
Feature of illumination more desira-
} BILE than in the tungsten system and
one which has been in Glenwood Springs
and in operation for many years and
1 has shown itself most satisfactory.
The figures here given can be check
3 ed by anyone from data published by
3 the manufacturers of the Illuminating
. devices mentioned.
The statement Aabbergasted the
trustees, and it evidently took the
breath out Of the Mutual advocate, Mr.
I King. All he could ind to say in reply
