Wasted Light ~ 20%+ LED Pole Lighting: - Less Sky-glow – Dark Sky Compliance - Directed Optics – No Upward Light Wasted or Refracted Losses - Optics Design – Less Light Trespass, Control Over Shaping of Pattern

Optical Design and Control

Better Vertical Illumination = Ability to See Pedestrians

Better Horizontal Illumination= See Roadway or Sidewalk Features

Less Waste




Wasted Light ~ 20%+ High Pressure Sodium (HPS) Street Light: Power = 128 Watts Lab Test Output = 6,432 Lumens Lab Efficiency = 50.1 Lumens/ Watt Delivered Lumens = 2,694 Lumens Application Efficiency = 42% Overall Efficiency = 21 Lumens/ Watt

Lighting Design - Color Choice ◦ Warmer Temperatures to emulate incandescent look

& feel ◦ Cooler Temperatures for nigh vision acuity

Fixed Source Temperature v. Selected Color ◦ HPS / Metal Decorative Pole Lamps – Fixed Color

Temp. HPS – 2,100K / Metal Halide – 4,200K

◦ LED Lamp Sources Available in Range of Color Temps

Color Temp (K) Source LED Choices

2,700K – 3,300K Incandescent Lamp 2,700K

3,000K Warm White CFL

4,100K Moonlight

5,000K Daylight Horizon

5,500K Daylight Noon

6,500K Daylight Overcast 6,500K




CRI – Ability to predict color appearance of an object under the light ◦ Distinguish a standard set of colors

Ability to naturally see colors of objects on pathways, roads, parking lots, etc.

Incandescent Lamp = 100 ◦ Older Standard / Familiar Source

Screw-In Designs ◦ Orientation – Has to be designed for base up

or base down for post tops or teardrops Heat dissipation requirements

◦ Places blub in same orientation as existing lamp sources

◦ Integrated or Non-Integrated LED Drivers ◦ Light Patterns – IES Distributions ◦ Rebates – Sometimes not available unless the

lamp is physically attached to fixture

Bolt-In Designs ◦ Often able to be oriented for Pole Lamps or

Teardrop Pole Lighting Styles ◦ Uses thermal mass of fixture housing and pole

for heat removal ◦ Driver typically located on bracket in housing ◦ Greater control of light pattern ◦ Typically better able to cutoff lighting for dark

sky requirements ◦ Rebates available
