303 and 304 Square Refractor

These 20” x 20” lenses utilize unique prismatic configurations that produce either a symmetrical or asymmetrical light pattern for maximum design flexibility.


These lenses are used for indoor or outdoor area lighting, including service station and parking lot applications. Compatible with vertically or horizontally mounted HID, halogen and compact fluorescent, and LED lamps sources.

Before final installation, dissipate static on parts by spraying with de-staticized air or by wiping with a clean, damp rag. This will help minimize dust build up.


  • Rated up to 400watts
  • Model 303 is molded of UV stabilized Clear Acrylic for high efficiency in general lighting applications.
  • Model 304 is molded with Clear Polycarbonate with or without UvaLex® for areas where breakage and high ambient heat are concerns.
