They will be used to refurbish buoy lights, navigation lights and a lighthouse along the coast, in the river and its estuary. Under the contract, Tideland has also supplied tools and equipment to restore the workshops of the Port Autonome de Pointe Noire, which is responsible for all aids to navigation in the country.

Both ML-155 and ML-300 MaxLumina lanterns feature a one piece acrylic fresnel lens designed to deliver maximum beamed light for the lowest possible power consumption. The ML-300 is capable of achieving up to 19,800 candela and a range of 18 nautical miles. For the Congo, the lanterns are equipped with Tideland's TF-3B MicroPower Omnibus flasher/lampchanger equipment, which incorporates a timer circuit card to permit input voltages up to 36V and provides up to 256 user selectable flash codes.

Tideland's RL-200 is a high efficiency range lantern designed to mark entrance channels, rivers, canals and straight channel reaches across bays. There is a choice of power systems, including the TF-3B or TF-3AC flasher/lampchangers or an LED based light source. In the Congo, the first option was chosen.

The TRB-400 will be used to replace the existing optics in the Pointe Noire lighthouse at the southern end of the bay of Pointe Noire. It has a maximum range of over 23 nautical miles.
