Moonlight Schedule Should 7e Dispensed
Wlth-Vliaee Paying for More Light
Than It Receives.
Following are some Of the principal
statements and suggestions In Mr.. Ad-
amss report;
Your arc street lamps are stated to
be of two sorts, rated at 1000 and 1900
nominal candlepower respectively but
from inspection of these lamps when in
operation and from certain statements
that have been made to me It seems GER
tain that these lamps are not receiving
as much energy as is usually expended
In lamps OF these ratings. In any future
contracts that may be made for arc
lighting the arc lamps should be des-
ignated by the watts to be expended In
each and then tests should be made to
show whether the contract is being ex-
ecuted. The ratings of 1900 and 2OOO cam
dlepower for arc lamps are merely NOM
inal and do not ensure definite guam
uty of light.
THE six lamps just named (referring
to the all-night lamps) operate with al
ternating current. and such lamps do not
give as much light by fully 25 per cent.
as do arc lamps that consume an equal
amount of energy in the form Of direct
current
Apart from your main streets. mean
descent street lamps will give much bet
ter results than arc lamps of the same
expense TO operate, because the energy
consumed In one of the 1000 candlepoweT
lamps Will operate five OF the Is candle
power lamps and distribute the light bet
ter.
1T is recommended that the six all.
night arc lamps be discontinued and that
incandescent lamps be used In their
places hnpatgR only n
or light Is necessary after midnight
Apart from the main streets all arc
lamps should be replaced by incandes-
cent lamps Both the arc and mean
descent lamps should be operated every
night In the year. whether the moon Is
supposed TO shine or not. All lamps ex-
cept few of the incandescent sort for
all-night service should be operated eOOC
hours per year. Lamps for all night SER
vice should be operated 1000 hours per
year. For each 1000 candlepower arc
lamp, operated 1000 hours per year with
direct current and adjusted to consume
the proper number OF watts q fair rate
Is $50 per year. the sum you are now
paying for operation during much
smaller number of hours. This rate for
arc lamps amounts to SO cents per
thousand watt hours. Each 25 candle
power incandescent lamp II supplied with
energy at the proper rate and renewed
AT least four times year, should be paid
Tor at the rate OF SIS per year of 2OOC
hours operation. This rate amounts 10
SO cents per thousand watt hours For
each 20 candlepower incandescent lamp.
supplied with energy at the proper rate
and renewed at least eight times a year
the rate should be $24 per year OF 4OO0
hours operation. This rate amounts TO
6S cents per thousand watt hours.
AS. far as a short Investigation de-
NRlnnnh IA
suIners for incandescent lighting in Brat
tleboro range from Is cents down to 10
cents per thousand watt hours. The
largest consumers of electric lighting
found I'm your village had lighting bills
of less than SO each for last January.
and only about ons-third of this amount
each for last May. In contrast with
these figures the village OF Brattleboro is
paying fully $500 per month or over $4,000
per year for street lighting. This amount
Is paid for street lighting not only be-
cause the load OF street lamps is prob
ably greater than the load of lamps for
any private consumer. but also because
the street lamps operate more hours per
day than do the lamps OF private con-
sumers. 1t follows that street lighting
Is the most desirable load connected to
the electric system In Brattleboro. and
since private consumers are supplied at
the rate OF 10 cents per thousand watts
street lamps should be operated at
lower rate.
From all available data II seems that
the rates above recommended of SO and
So cents per thousand watt hours for
half night lighting. and 6.S cents for all
night lighting. are fair to both your viii
lage and the lighting company. These
rates, IL adopted under the conditions
suggested, will give Brattleboro a much
Improved lighting service at IA saving of
some hundreds OF dollars annually in
comparison with the present lamps and
rates. The test of reasonable rates most
favored by the courts is that they snail
yield a fair return on the structural
value OF the property necessary for and
devoted to the public service. Ii has not
been possible to apply this test to the
rates at Brattleb0ro because nothing
definite could be learned as to the value
OF the electric system or its net earn
ings, though this and other information
bearing on the subject was sought
Recent improvements in the art prom
tse great Increase OF the amount of
light developed by a unit of electric en-
ergy, and the interests OF the village on
this point should be provided for in any
