percent humidity. Operate the lamp in the horizontal position. Ensure that the
glass envelope and base have a maximum seal temperature of 662 °F (350 °C).
Ensure that the glass is free of any impurities that might allow moisture build up
within the lamp. Ensure that the glass envelope of the lamp is indelibly marked to
show: original manufacturer’s identification, rated voltage, rated lumens, rated
average life, rated wattage, date of manufacture, and batch code.
Furnish materials according to the Department’s Qualified Products List (QPL).
C. Vehicular and Pedestrian Light Emitting Diode (LED) Lamps. Prequalify
vehicular and pedestrian LED lamps according to Supplement 1097.
Furnish LED signal lamp units that meet or exceed all the requirements of the
current Institute of Transportation Engineers (ITE) publications - Vehicle Traffic
Control Signal Heads (VTCSH) - Light Emitting Diode (LED) Circular Signal
Supplement 2005; Pedestrian Traffic Control Signal Indications (PTCSI) - Part 2:
Light Emitting Diode (LED) Pedestrian Traffic Signal Modules and Vehicle
Traffic Control Signal Heads - Part 3: Light Emitting Diode (LED) Vehicle Arrow
Traffic Signal Modules, unless otherwise stated herein. . LED module shall be
certified by the Intertek LED Traffic Signal Module Certification Program.
All LED signal lamp units shall be the latest model currently in production
and new. Equipment no longer being manufactured shall not be accepted, even if
it meets the following specifications.
LED signal lamp units shall conform to the following criteria:
1. Physical and Mechanical Requirements
a. The LED traffic signal lamp unit shall be designed as a retrofit
replacement for existing incandescent signal lamps and shall not require any
special tools for installation. The 12"(300 mm) retrofit replacement LED traffic
signal lamp unit shall fit into existing traffic signal housings built to ITE VTCSH
standards without modifications.
b. Installation of a retrofit replacement LED traffic signal lamp unit into an
existing signal housing shall only require removal of the existing lens and
incandescent lamp. The new unit shall fit securely in the housing door and connect
to existing electrical wiring or terminal block by means of simple connectors.
Removal of the reflector is optional.
c. Each LED signal lamp unit shall be identified on the back side with the
following:
1) Manufacturer’s name and trademark
2) Part number
3) Serial number
4) Voltage rating
5) Power consumption (watts and volt-ampere)
6) Vertical indexing indicator (i.e., “up arrow”, or the word “UP” or
“TOP”) if specific orientation of the module is required.
7) Date of manufacture (minimum information required - month &
year)
Single units shall have identification markings as to the type and color of the
module. Bi-Modals shall be marked with module type.
