LED Sector Lantern E8591
The LED Sector Lights E8591 utilize high-efficient LED technology to provide narrow
high intensity 3-colour sectored light beam guaranteeing the visibility range of
up to 10 nautical miles at night time. The light consists of a light unit
and of a marine grade aluminium enclosure. The light unit consists of transparent
polycarbonate front cover and of anodized base board which is used 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 the 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
