LED Buoy Light E822

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

The Buoy Lights of the family E822 utilize high-efficient LED technology to provide omnidirectional flashing light beam to be used as in sea buoys as well on shore.  The lights consist of one or two LED based light sources, of a built-in flasher, and of marine grade aluminum enclosure with a flange and cable plugs. The flanges are available in two versions making the lights usable in different buoys (see Specifications). The lights are currently available in one of the five colours: red, green, white, yellow, or blue.

Under the flange a telecommunication controller with GPS receiver can be installed, the antenna of which will be fixed on the top of the light. Using this additional equipment the lights can be integrated into a remote control and monitoring system.

In order to protect the lights against mechanical shocks and harsh environmental conditions the lights installed under a polycarbonate cupola. The visibility range of the lanterns depending on the colour is from 2.6 up to 3.6 nm when using one light source, and from 3.3 up to 4.9 nm when using two light sources.


  • the solid state built-in flasher of the system using a programmable microcontroller performing the control of flashing  in accordance with the pre-configured light patterns, and  daylight switching ON and OFF of flashing by the  light sensor
  • when equipped with communication controller and GPS receiver, a number of additional features will be available:
  • communication with the remote control and monitoring system using GSM900 mobile telephone network.
  • setting of the time schedule of communications and responding to  the inquiries
  • executing of the commands received from the centre, and correcting of  the  built-in clock by  the  GPS signals 
  • checking the correspondence of the geographical coordinates of the light to the pre-configured  values and sending warning messages to the centre in case of  unacceptable deviation
  • programmable scheduling of mobile phone standby mode in order to save energy
