Thousands of sea turtles are affected every year because of the electric lighting along beachfront properties and coastlines around the country. According to the Sea Turtle Conservancy (STC), 90% of sea turtle nesting in the United States takes place on Florida beaches. For more than 20 years, the organization has worked to tighten the guidelines on beaches where property owners are restricted to amber light sources when visible from the beach to avoid the hatchlings disorientation.
According to the Florida Fish and Wildlife Commission (FWC), turtle-friendly luminaires must limit short wavelength light under 560 nanometers. The table below shows the amount of energy emitted at each wavelength for a typical 5000K LED source showing significant energy (36% of total) emitted below 560nm which is highlighted in blue.
