Navaid Energy’s (NE) Marine LED Lantern (Model- NERB-20NMF) is a highly efficient long-range marine rotating beacon with higher optical efficacy to provide a range greater than 22NM with narrow beam of 1.5° to 2° divergence angle for achieving highest range with lowest power, cost effective, maintenance free service as it is electronically controller rotating beacon has no mechanical rotating apparatus, can be easily installed. The special Navaid Energy’s narrow beam angle makes it highly optical efficient long range marine lantern. The NERB-20NMF is sturdily built to high specification to maintain its optical and electrical properties throughout its lifetime.
