A New Zealand manufacturer of LED fixtures has turned the technology to an innovative use - protecting the country's sea turtles.
Axiom offers outdoor lighting for beachfront hotels, using Nichia LEDs which operate at a wavelength invisible to the creatures.
Stephanie Prather, director of sales for Axiom, said artificial lights confuse the hatchling sea turtles, causing them to wander inland where they are in danger of dehydration and road traffic.
"New laws in Florida as well as efforts in other responsible countries like Australia and New Zealand are looking at ways to light the way for humans, yet protect sea turtles from running aground in the wrong places," she added.
The turtle-friendly lighting products sell for about the same price as the halogen and incandescent or compact fluorescent bulbs they replace.
All species of sea turtles are currently classified as threatened or endangered, as new fishing methods and beach developments make their habitats unsafe.
