How to Retrofit Right the First Time The Fundamentals: Uplight & Waste 20 o Highest Intensity Critical Photometric Performance 70 o Source of Glare – gives the appearance of brightness but is wasted light Highest Intensity 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 The Retrofit Goal: Meet or exceed the performance of the existing light source per IES standards

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.
