69 <br /> <br /> <br /> <br />Figure 34. INDUSTRIAL DISTRICT PEDESTRIAN LIGHTING RETROFIT CONCEPT: Existing roadway streetlights in the industrial areas today have a <br />single existing high pressure sodium (HPS) “cobrahead” luminaire and arm. These poles could be potentially be retrofitted with one new <br />roadway height LED luminaire and arm (same orientation as existing) and one (as shown above left) or two pedestrian height LED luminaires + <br />arms (two would be in the same line and perpendicular to the existing roadway arm). Power use would most likely be the same or less than <br />existing, allowing existing circuits and footings to remain the same. This would create brighter streets (especially for pedestrians) and add a <br />“tech” theme to workplace district streetscapes at low cost. A “Boulevard” corridor street could be provided with the twin-pedestrian luminaire <br />configuration for a larger-scale character; a “Back Street” location could be provided with a single-pedestrian luminaire configuration for a more <br />modest scale. Where budget permits, new supplementary single pedestrian poles (shown at right) could be installed in between widely-spaced <br />existing roadway poles for more uniform coverage.
