In developing the new small-aperture LED downlights, Dasal teamed up with channel partner SESCO Lighting Inc. SESCO works with numerous wildlife conservation organizations and has participated in hundreds of successful “turtle lighting” projects.
Rare loggerhead, leatherback and green turtles return each year to nest on the stretch of coastline where they hatched. Bright lights nearby may discourage females from coming ashore to nest. But more important, newly hatched sea turtles can become disoriented by manmade lighting and fail to find their way quickly to relatively safety of the sea.
Over 100 million years, baby sea turtles developed instincts to immediately crawl toward the lightest horizon: toward the ocean and away from the dark dunes. But today, instead of heading directly into the sea hatchlings go toward the bright lights of homes, buildings and roadways. Those that wander in circles on the sand have a much higher risk of dying of dehydration, exhaustion or predation.
To protect the emerging hatchlings, turtle lighting ordinances along the Southeast’s highly developed coastline mandate careful positioning and aiming of full-cutoff light fixtures. Studies show that certain light wavelengths have minimal effect on sea turtles, so long-wavelength yellow or red lighting is also required.
Many property owners choose amber LED replacement bulbs for sensitive nesting beaches, but unfortunately place them in light fixtures not designed for turtles or LEDs.
The round Aqua Amber LED and square Nemo Amber LED trims and associated housings from Dasal Architectural Lighting produce light exclusively in the “turtle safe” wavelengths at 588 nm. These dedicated LED downlights are holistically designed with a deeply regressed, highly directional light source to reduce glare and spill light; plus optimal thermal management to ensure performance and long life.
