How to Retrofit Right

Bright may not be good enough – many people evaluate a light source based on how bright it appears. This seldom factors in national lighting standards and issues like glare, uniformity, light levels at distance, and more. Getting the performance you need takes a high performance directional LED source.

Vega Light Control Systems retrofit solutions give you the power and performance to replace high output light sources with LED without degrading the system performance. We use some of the industry’s best lighting engineers and some of the highest performance optics, LEDs, drivers, and surge suppressors to deliver a system second to none. The following information will show you how we do it.

The Fundamentals:

How to retrofit right

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.Vega Light Control Systems use only highly
engineered optics to manage light.
