Buoy Lantern E807
We regret to inform you that this product is DISCONTINUED; please find our current products here
The Buoy Lantern E807 is a LED-based marine signal
lantern with a built-in flasher for application in sea buoys and moorings, as well as in
various fixed lights.
The visibility range of an E807 lantern with one E80x LED disc light source is about 3 NM (according to the Visibility Range Table below); however, the range is easily extended by stacking several LED discs from the E80x family on the lantern. We can offer different configurations of the E807 Buoy Lantern with up to 5 LED discs according to the required range and color.
General benefits of using
LED-lanterns
Long
lifetime (up to ten years). This makes the maintenance costs of
LED-lanterns, in comparison with
traditional
light bulbs, much lower because there will be no need in frequent
and expensive maintenance
trips
to lights only for the purpose of changing of failed bulbs.
Significantly
lower power consumption (up to 1.5 times) due
to higher efficiency of LEDs. This is very
useful
when using them in primary battery powered sea buoys, as well as
in case of lighthouses and
beacons
powered by solar or wind energy.
No
need for colour filters and additional optics. The color of the
light of LEDs is determined by the physical
properties
of light-emitting semiconductor crystals used in them, i.e. by the
type of LEDs. Therefore,
no
additional colour filter is needed which would cause some loss of
light intensity.
Features
-
Programmable automatic control of flashing operation
-
Daylight-dependent activation of flashing using a photosensor
