NEPTUNE: adjustable professional projectors in 316L stainless steel for installation under water, for low voltage halogen lamps, monochromatic and RGB LED. All the metal parts are made of 316L steel, a metal that ensures high resistance to sea air and chemical agents so as to make the NEPTUNE particularly suitable for underwater installation even in seawater, in addition to fresh water. The projectors classified IP68 cannot be installed under water permanentely according to international standard IEC 364-7-702 (max 12V A.C. o 30V D.C. in the water). They can, however, withstand temporary accidental immersion to a depth of 1.3m. For precision aiming of the NEPTUNE projector, it is fitted with a toothed bracket for secure, stable long-term tightening even when installed in moving waters.
