Street Light Repairs and Facts
City of Mesa
streetlights are NOT numbered. The two digit
numbers on the light fixture tell the Technician the
wattage of the lamp: 10 =100 watts, 15= 150 watts,
40 = 400 watts, etc. This is why we ask you to
provide a precise location or address when reporting
an outage. If the streetlight does have a
five-digit number on the pole, it is maintained by
the Salt River Project, 602-236-8465, not the City of Mesa.
Cycling Lamp
High-pressure sodium lamps have an expected lifespan
of five to six years but must warm up for a few minutes to produce full luminance.
Failing lamps draw excessive electric current and will shutdown until
they cool off and can restart again. This off/on pattern is called Cycling.
As the lamp gets older the "on" time shortens until it is off most of the
time.Day-Burning Lamp or Circuit
A photocell is a light-sensing switch on top of the
luminaire that turns the light on at dusk and off at dawn. The photocell
may be connected to a lighting control cabinet and turn on multiple
lights hooked in to the circuit. When a photocell is damaged, the light or
lights will remain on during the day. Operation of the lights during
the day not only wastes energy but also shortens the lifespan of the lamp and
its components.
Multiple Outages
Multiple outages typically occur when several adjacent streetlights are out.
This may result from a failure in the lighting
control cabinet or in the underground wires. Circuit outages are treated
as high priority because of the large areas effected.
Knock Downs, Vandalism, Exposed Wires
Last year, 73 streetlights were damaged by vehicles, requiring full replacement or major repairs.
In addition, 108,019 feet of copper wire were stolen, 148 poles were replaced due to rust damage,
and vandals broke out numerous streetlight lenses with pellet and paintball guns.
Please report any vandalism to the Mesa Police Department. Always
stay clear of a pole that has
been hit, is moving excessively, has loose components that are hanging
down, or has any exposed wires.
