  Omnidirectional LED Lights Family E825 

We regret to inform you that this product is DISCONTINUED; please find our current products here
 

The Omnidirectional Lights of the family E825 utilize highly efficient LED technology to provide omnidirectional flashing or steady light beam for use in coastal applications, as well as on various moving vessels.  The lights consist of one to five LED based omnidirectional light sources with lenses, of a built-in solid state flasher, and of a marine grade aluminum case  with a flange and cable plugs.  Three customer-selectable lense types with different optical properties can be used for light beam formation to provide a required vertical divergence of 5, 10, or 20 degrees. The lights are currently available in one of the five colours: red, green, white, yellow, or blue.

 

Features

 

  • utilizing highly efficient LED technology guaranteering long lifetime and high reliability of the lights
  • the solid state built-in flasher of the system is based on a programmable microcontroller, providing the control of flashing in accordance with the pre-configured flashing patterns, and light sensor controlled switching ON and OFF

  • by ordering E825 lights with lenses of various optical properties, the customer can select the most suitable vertical divergence, and consequently, the visibility range
