Sea Turtles require a special wavelength of light so that they are not disturbed when coming ashore. The trick is balancing the lighting needs of the public and the protection of the sea turtles. Amber LED's operating a a color wavelength of 590nM complies with marine turtle safe lighting requirements within coastal regions.
Sea turtles are either endangered or threatened (the loggerhead is the only species that has a population high enough to be only threatened in Florida). They are protected under the Federal Endangered Species Act of 1973 and Florida’s Marine Turtle Protection Act (379.2431, Florida Statutes).
