Omnidirectional LED Lanters E8272                                          

The lanterns of the product family E8272 (hereafter, Lanterns) utilize high-efficient LED technology to provide high intensity omnidirectional light beam for application in shore-based navigational lights and are designed for long term operation in harsh environmental conditions. An E8272 Lantern consists of a light sensor, of a controllable power supply for LEDs, and of an overvoltage protector. Light operation is controlled either by optional built-in flasher, or by auxiliary flasher of any type. The Lanterns are typically supplied with adjustable mounting feet for levelling, and a hard-wired power and control cable of 5 m length. Optionally, the Lanterns can be equipped with power connector. The Lanterns can be delivered in several configurations with varying light colour, intensity, and optional built-in flasher:
