TRANSCRIPT
70o
Spec Compliant Light Source:• Drive the light out without waste and glare• Produces uniform illumination • Minimal uplight or glare• Light at or below 70° critical• IES compliance requires uniformity• Dark skies compliance• Rebate approval
Highest Intensity
The Retrofit Goal:Meet or exceed the performance
of the existing light source per IES standards
Uplight & Waste
Critical Photometric Performance
Source of Glare – gives the appearance of brightness but is wasted light

Successful LED Retrofit:
Important Principals to Understand:• High Pressure Sodium is very efficient (90-120 LPW)• Most LED systems are about the same efficiency (80-120 LPW)• How can someone replace HPS with LED and get an energy savings without reducing light
levels and coverage?
Efficient light control is the only way an LED system can replace high pressure sodium without violating national ANSI/IES lighting standards
Most corn cob style products have little to no light control. MaTech uses only highly engineered optics to manage light.
