LS 100 LED Range Light Signal High Performance
As with all modes of transport, the lighting systems used by the night are imperative to the vehicle’s safety. Ships, being enormous constructs, needs lighting systems too! In fact, the lighting system in place for a vessel is integral to the safe navigation of the vessel; in fact, it is one of THE MOST important aspects of nautical studies emphasised on in college as well as for competency exams.
The primary function of marine navigation lights is to aid prevention of any major accident from happening. All boats – whether big or small are required to have night lights as a part of the navigation systems. This system was introduced in the year 1838 by the United States and then was followed by the United Kingdom in 1849. In the year 1889, the International Maritime Conference was established by the United States to establish proper guidelines to prevent marine accidents. In the year 1897, these rules were officially adopted internationally. The colour of the lights that were required to be used as specified by a set of rules passed in the UK. On the basis of this rule, three colours were chosen: red, green and white. Even today, the marine navigation lighting consists of these three colours.
There is a pattern in which these lights are set up on the ships and boats in conjunction with the International Association of Lighthouse Authorities (IALA) Buoyage Systems. The pattern can be explained below :
Both the sidelights show an unbroken light over an arc of the horizon of 112.5 degrees such that from right ahead it can be viewed to 22.5 degrees shaft on either side.
A white light is also placed at the back of the boat (known as the stern side). This shows an unbroken light over an arc of horizon of 135 degrees and fixed to show the light 67.5 degrees from right aft on each side
The mast of the boat also has to have night lights. The colour of this light is white. Two mastheads lights are in place, with the second one shaft of and higher than the first, when the length of the vessel is greater than 50 metres. Shows an unbroken light over an arc of the horizon of 225 degrees and so fixed to show the light from right ahead to 22.5 degrees abaft on either side
The LS 100 LED signal is designed for applications requiring short and medium range directional light, such as range lights and port traffic signals.

Marine lanterns are fixed, all-weather lighting devices used to aid navigation on the water. They are designed for use as aids-to-navigation on small buoys and in marinas, rivers, harbors, and aquaculture installations to mark dredging operations and for a host of other applications where hazard lighting is required. They may meet Class A and B applications and deliver brightness and intensity of up to 18 nautical miles.
Solar marine lanterns have highly leveraged the use of LEDs and solar energy technology. A marine lantern could likely be the perfect combination for these technologies. Solar energy is bountiful and can be counted on for a reliable unobstructed power source. LEDs are compact, use relatively little power, and when packaged together properly can withstand some of the harshest weather conditions.
Wired/cabled marine lanterns are available as a traditional and reliable choice for where high luminous applications and long running hours are required.
Colors and Visibility
Marine lanterns are available in a variety of colors to suit navigation or marker applications. Common colors include red, green, white, yellow, and blue.
A key differentiating specification for marine lanterns is the distance from which the lantern can be seen. United States Coast Guard (USCG) approved Class A lanterns can be seen up to 5 nautical miles away. Class B lanterns can be seen up to 3 nautical miles away.
Many marine lanterns operate as a continuous marker or can be set to over 200 rhythmic flashing settings to conform to the Association of Lighthouse Authorities (IALA) flash guidelines. Marine lanterns meet the Aids to Navigation (AToN) and Private Aids to Navigation (PAToN) recommendations established by the International Association of Lighthouse Authorities (IALA).
