Port of Boston Opts for Self-Contained Lanterns
01 Sep 2002
The Port of Boston in Lincolnshire UK has chosen two Tideland MLED-120SC self-contained lanterns to help mark the navigational channel from the Wash. The busy East Coast port handles vessels of up to 4,000 dwt, with trade links throughout Europe and Scandinavia.
The MLED-120SC is a self-contained version of the company's diode based MLED120 lantern. It consists of a single solar powered unit using light emitting diode (LED) technology to provide a high intensity light with low power consumption and minimal maintenance over an estimated 20 year life. The MLED-120SC DA-65 diode array consists of 30 precision, high intensity LEDs mounted in a Tideland parabolic mirrored reflector to provide an even 360º light source.
Two switches control 256 flash characters.
The navigational channel to the Port of Boston is already marked by solar powered lanterns which feed batteries to power separate light units. The decision to replace two of them with Tideland's single unit lanterns was taken in order to minimise maintenance and reduce the number of separate components kept in stock.
The lanterns are mounted on buoys that initially required modification to accept the unit, but no further maintenance is anticipated during the lifetime of the diodes and batteries.
The lanterns marking the channel to Boston are situated at one mile intervals. The intensity of the light generated by the LEDs is such that a low power setting is sufficient to give a two mile visibility in local conditions.
