MEL 500L

The MEL 500L Port Entry Light (PEL) is a sector leading light of maximum resolution between its colour sectors, made up of a LED light source, able to provide a day range of up to 5 nm and a nominal night range of 23 nm.

The main advantage of this beacon is its accuracy between its colour sector boundaries (<0.05º). Light emission generates a unidirectional beam in three colours, with a horizontal divergence between 1º and 15º. Colour sector configuration is expressly done for every case. The use of high-intensity LED diodes ensures minimum consumption, maintenance free.

MEL 500L light is designed according to IALA Recommendations and Guidelines, providing a great aid to the navigator to know its position in the channel. As an option, it can be delivered with oscillating boundaries, thus offering accurate information on his lateral distance from the leading axis.
