Vandal resistant lighting has evolved. At one time, any fixture that contained polycarbonate was considered a security fixture. Today, we offer the only fixtures that from concept to final production are engineered to meet the stringent demands placed upon a vandal resistant light. Using advanced computer techniques, such as 3-D modeling and finite element analysis, we have increased the yield strength of our lenses by as much as one third over traditional designs. Additional benefits of our investment in high technology include aesthetic improvements as well. For instance, utilizing the latest mold design software, we were able to eliminate visible witness marks from our refractors, resulting in a cleaner, more pleasing appearance.
