NOTICE TO ALL DESIGNERS AND CONTRACTORS
The Portland Bureau of Transportation (PBOT) has begun implementation of a new lighting efficiency program.
This notice is to inform all designers and contractors that the use of Light Emitting Diodes (LED), and in some cases, Induction technology, is now standard street lighting practice.
Although some documents may still specify the use of High Pressure Sodium (HPS) lamps, HPS is NO longer standard for street lighting projects.
If the construction of street lighting approved plans has not been initiated, then the plans need to be redesigned to use LED lighting fixtures.
We recommend that you consult the street lighting engineer assigned to your project, who will provide guidance as to the light source that should be used. This process should be followed for both projects and are in design and those that are going into construction.
In general, project estimates should NOT be developed with the assumption that HPS lamps will be used.
