Test Program

_________________________________________________________________________________________________________________

Introduction

The City of Flagstaff is currently in the process of testing five (5) new types of Light Emitting Diode (LED) fixtures in five (5) different locations; the Cheshire Neighborhood, Butler Avenue, Fourth Street, Route 66, and the intersection of Cedar Avenue and West Street. At these locations, the City will be replacing old Low Pressure Sodium and High Pressure Sodium fixtures, which will not be supported in July of 2019, to new LED fixtures. The goal is to maintain appropriate lighting levels, while not adversely affecting the City's dark sky natural resources or the missions of the Lowell and U.S. Naval Observatories.

Light Distribution Type

Type 2

The type II distribution is used for wide walkways, on ramps and entrance roadways, as well as other long, narrow lighting. This type is meant for lighting larger areas and usually is located near the roadside. You'll find this type of lighting mostly on smaller side streets or jogging paths.

 

Type 3

The type III distribution is meant for roadway lighting, general parking areas and other areas where a larger area of lighting is required. Type III lighting needs to be placed to the side of the area, allowing the light to project outward and fill the area. 

Type 4

The type IV distribution produces a semicircular light meant for mounting on the sides of buildings and walls. It's best for illuminating the perimeter of parking areas and businesses. The intensity of the Type IV lighting has the same intensity at angles from 90 degrees to 270 degrees.
