It has been discovered that light shining brightly from buildings within 1,000 feet of the seashore attracts marine turtle hatchlings away from their natural environment at sea.
Due to the phenomena, the Florida Model Lighting Ordinance for Marine Turtle Protection requires architectural glass to transmit no more than 45 percent of the light from inside the coastal buildings. Originally, Versalux Blue 2000 was intended to transmit more than 45 percent of interior light. But, research indicated that a darker blue glass would not only better serve environmental needs, it would be more attractive. The resulting Versalux Blue 2000, by transmitting only 42 percent of light, complies with the coastal lighting code and is presently specified for numerous Gulf Coast buildings. Since the introduction of Versalux Blue 2000, additional products have been developed by Visteon Float Glass Operations that comply with the ordinance
