BETTER LIGHTED
Electrical Engineer Reports
Aggregate CandIepoWer In
!. creased So Per Cent.

Continued modernization of the Dis
trict's street lighting system during
the last fiscal year, ending June 5 4,
increased the aggregate candlepower
about SO per cent. according to the
annual r. IT of Warren b. Hadley,
electrical engineer, submitted yester-
day to the Engineer Commissioners,
Col. William B. Ladue.
The improved lighting system, how
ever, Mr.. Hadley pointed out, has been
limited in general to the main traffic
arteries and to streets being repaved.
1.-THE resulting improvement of visi-
bility," he said, sis a certain comfort
to those using the streets at night,
and / believe has contributed to de-
crease of hazard to life, limb and prop
erty. T,,.a ..ew installations certainly
contribute to the Identification OF thf
city"
Lighting Project Outlined.
The keynote of the new lighting
project, Mr.. Hadley explained. is larger
units, higher mounted, which nave re-
suited in greater Improvement OF VlSl'
bility and making practicable the use
of glassware having a much higher
value of light transmission. New de-
signs of posts, or rather. taller mem
bers of the family of 'Millet' posts. de-
signed for Washington in 1911. he
said. "are used on the more lmpor-
tant thoroughfares, having mounting
heights of from Is to 90 feet, and all
old posts displaced are placed else
where after being supplied with an
extension piece of 10 or % inches, In
creasing the length to mounting
heiehts of 12A to 10 feet, and fitting
with the new Washington type glass
ware"
. The report also pointed out there
has heen an increase of Sc in the num-
Der of 6.6-ampere magnetic arc lamps
to SIT and a decrease of az IN the
number of 4-ampere magnetic arc
lamps to $50, a net increase OF Il IN
the total number of arc lamps TO 9oo.
"The project" it said. "contemplates
eventual displacing OF all the less elI'-
cient 4-ampere lamps.
New Lamps Strikingly Effective.
.'The new type 6.6-ampere lamps
with the Washington type glass Is
strikingly effective, and the color value
of it's light, contrasting with that OF
show windows, gives better Senerai
effect, both esthetically and practl'
callv. than the incandescent street
the highest economical efficiency.
Lamps of this type on ornamental
posts were installed during the year
on E street from Fifth to Thlrteentn
streets. Eleventh street from Penn
sylyania avenue to G street. NJ street
from Twenty-seventh to Thlrty-slXth
streets and on Wisconsin avenue IRON.
M street to Volta place.
The number of incandescent lamps
added during the year coupled with
those discontinued, the report explain
ed. made a net increase of 2.462, whlie
there was a net decrease of 901 IN the
number Of gas lamps in. service. Tnere
also was a. net increase OF lS In the
number Of designation lamps ADDED
during the year.
More Fire Alarm Boxes Needed.
Mr.. Hadley recommended rapid ex-
tension of the fire alarm system ana
stressed especially the need or boxeS |
I'm the suburbs There appears TO |
be a tendency to assume that the |
prevalence of telephone connection |
renders more liberal distribution or |
fire alarm boxes unnecessary, ne oe-
clared. Experience here and else
where does not sustain the position.
Notwithstanding special skill in trans
lating messages from persons natural
ly excited, it frequently happens tnat
a telephone call is not competent.
Mr.. Hadley also called attention TO
the inadequacy of the present equip
ment signal system, ana SAID thaI
further consideration is being given
to a proposal to utilize radio Tor TINS
purpose.
