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
LED Street Light:
Power = 63 Watts
Lab Test Output = 5,304 Lumens
Lab Efficiency = 84.6 Lumens/ Watt
Delivered Lumens = 3,006 Lumens
Application Efficiency = 57%
Overall Efficiency = 48 Lumens/ Watt
128% Improvement

Lower Light Levels– Less Light Trespass

 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

 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
