500MM LANTERN
P R B

This ,500mm, type of lantern with 3600 visibility spectrum were used in Islands and peninsulas where the light beam is required to be seen from all angles. The 500mm drum optic fitted inside is compressed moulded and polished. Normally flashing lamps are used as illuminant inside drum optics. The acetylene gas flashers used in these type of optics are now replaced by electronic flashers with halogen lamps

In PEDESTAL ROTATING BEACON [PRB], light beams are formed without using the combination of prisms and lens(optics). The lamps used in this apparatus are set to project light to longer distance. The lamps are set in different angles and the panel is rotated at constant speed to create flashing light with unique character.
