ekta™ LED Range Lights E8271

Range Lights E8271 utilize highly efficient LED technology to provide narrow light beam in horizontal plane for application in range lights. The light consists of an aluminium pedestal for mounting, a pipe-formed support/enclosure, a signal head module for electronic circuitry, and a plastic hood. The E8271 is a cost-efficient visual signalling solution intended for reliable long-term operation in field conditions.

The 8271 Range Lights are currently available in one of the four colors: red, green, blue, or white, and in one of the three light beam configurations with two options:
       - high light intensity and narrow horizontal divergence;
       - lower light intensity and wider horizontal divergence;
       - lower light intensity and extra wide horizontal divergence;
       - optional built-in solid state flasher;
       - optional hard-wired power supply cable connection.

Features

designed using revolutionary, energy efficient and ultra compact Luxeon STAR^TM solid state light sources, combining the lifetime and reliability advantages of Light Emitting Diodes

compact design and small dimensions make the Lanterns E8271 particularly suitable in many locations

external control of flashing using a flasher of any available type

new versions of the lights featuring a built-in flasher and a light sensor are currently under the develöpment
