• Project involves refurbishment of lighthouse and shore beacons on Black Sea coast

Tideland Signal has supplied a range of high-performance LED-based warning lights for a major repair and maintenance project on aids to navigation along the Black Sea coast of Bulgaria.

The project was carried out by a local company Alfori Ltd. on behalf of the Bulgarian State, which involved the refurbishment of a number of lighthouses and shore beacons at Burgas, Nesebar, Primorsko, Rossenets, Tsarevo, Ahtopol, Kavarna and Balchik.

The process involved replacing the old traditional, incandescent lanterns with modern Tideland LED lanterns.

The lanterns included one MLED-300, two MLED-155 and seven MLED120SC’s. A quantity of 30 MLED-120SC lanterns were also supplied for mounting offshore on refurbished buoys along the Bulgarian coast.

The MLED-300 and MLED-155 LED lanterns are fitted with MaxiHALO 60 LED flashers, mounted in theMaxlumina lens. The solar-powered model installed in the Burgas lighthouse achieves >1400cd, a nominal range of 10 nautical miles >16 NM @ T=0.85) with a power consumption of only 8.7W.  Also solar-powered, the six MLED-155s installed on the entrance beacons at Burgas and at Primorsko are configured for ranges from 2NM to 6NM. 

Tideland's high-intensity LED technology, backed by advanced power conditioning circuitry delivers extremely high reliability and long service life both offshore and in land-based installations. In particular, the power efficiency of the Tideland range makes it highly suitable for buoy mounting, beacons, offshore structures and other solar-powered applications.
