Be- quette worked closely with VOLT® Lighting, Tampa-based lighting manufacturer, to cus- tomize the required fixtures. Several fixture models were used including Elevator™ brass path lights and floodlights and Infiniti G3 brass LED spotlights. Ok for Turtles, but Will Humans Like It? There were many challenges in the project. One of these was to create amber area light- ing around the large pool. And, to use am- ber illumination on pathways that led to the beach. Amber lights are not typically used as general area lighting and there was a concern that guests may not like so much of the oddly colored light. To mitigate the monochromatic effect, Be- quette used spotlights with warm white light sources – but only in very selective ways. Us- ing spotlights aimed away from the beach, with oversized glare shields, he up-lit many of the palm trees with a minimal level of the white light. He tested these to make sure the amount of reflected light towards the beach was acceptable. He also put these lights on circuits separate from the amber lighting – so the white lights could be shut off during prime turtle nesting seasons. Environmental Collaboration The Sheraton Sand-Key project was a suc- cessful collaboration among many parties committed to environmental protection. These included the owners and managers of the hotel, the light manufacturer, Brilliant Nights and turtle experts from the nearby Clearwater Aquarium. If we strive to be lighting designers com- mitted to quality, then we should always consider how our work affects the environ - ment. Note the following definition from the Illumination Engineering Society: "Lighting quality: The intersection of hu- man needs, architecture, economics, energy, efficiency, and environment." While (in the definition) environment is the last word, in some cases, such as with turtles, it is the most important one.

Turtle-friendly lighting guidelines are set by the Florida Fish & Wildlife Conservation Commission (FFWCC), and enforced by the U.S. Fish & Wildlife Service. These guidelines have the following main components: • Keep it Low. Mount the fixture as low as possible, and use the lowest amount of light needed for the task. • Keep it Shielded. Fully shield the light so bulbs and/or glowing lenses are not visible to minimize light trespass. • Keep it Long. Use long wavelength light sources (ambers and reds) in the appropriate lighting fixtures. Right: For added protection to the turtles, the fixtures with white sources were put on different circuits than the amber lighting so they could be turned off during prime nesting times.
