LED Range Lantern E855
We regret to inform you that this product is DISCONTINUED; please find our current products here
The Range Lantern
E855 utilizes efficient LED technology to provide narrow high intensity
light beam guaranteeing the visibility range of up to 15 nautical miles at
nighttime. The lantern consits of a light unit and of a marine grade aluminium
enclosure. The light unit consists of a transparent polycarbonate front cover and
of anodized back cover which is used also for dissipation of the heat.
On the site of installation
the lantern will be fixed by a hot zinc coated base plate. The direction
of the light beam around horizontal axis is adjustable by rotation of the
case with the light unit. Around vertical axis the direction of the light
beam is adjustable by deflection of the light unit.
Features
- designed using revolutionary, energy efficient and ultra compact Luxeon™ Star solid state light sources, combining the lifetime and reliability advantages of Light Emitting Diodes
- high intensity (up to 11,000 cd) narrow light beam, adjustable
around vertical and horizontal axes
- external control of flashing using a flasher of any available
type
- the light unit consists of two groups of LEDS with autonomous
power supply and control. This allows to:
use one group of LEDs as a standby (secondary) lantern;
operate at only half light intensity when necessary;
improve the reliability of the lantern – when one group becomes
faulty, another one will continue to operate.

New versions of
the lantern are cureently under the development,featuring GSM communication
controller and GPS receiver, allowing to integrate the lantern
into remote monitoring and control system. and to synchronize the flashing
of a group of lanterns by the GPS time signals.
