EKTA logo LED Range Lights E8511 and E8512

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

The E8511 and E8512 Range Lights utilize LED technology to provide narrow  high intensity light beam, controlled by a built-in flasher. They consist of marine grade  aluminium case, hot zinc coated base plate and polycarbonate light unit housing for the  LED matrix, flasher unit and power supply. The light unit is protected to IP67 and contains a silica  gel humidity absorber package. 

The   light  E8512 differs from the light E8511 by mounting arrangement: it is delivered without the steel base plate. This light will be fixed  to the host structure by a bent  fringe. The lights can be installed on site  without any additional cupola. The direction of the light beam is adjustable within 12 degrees around  both  vertical and horizontal axes using a detachable sight.



  • high intensity (up to 2000 cd) narrow light beam, adjustable around vertical and horizontal axes
  • programmable automatic control of flashing
    daylight-dependent control of the flashing mode by an internal photosensor
  • readiness for connection to  RS-485 local area net-work (optionally RS-232 interface is available)
  • when equipped with an optional GSM communication controller, the light can be integrated into a remote control and monitoring system
  • when a group of  lanterns is equipped with  optional  GPS receivers, the  flashing of this  group of  lanterns  can be synchronized without physical (cable) connection between the units
