4. 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.
