The SOBL obstruction lights are based on two lighting lamps a low intensity obstruction of 10cd and 32cd, each od which produces a luminous flux visible in the vertical plane in the range from 4 to 20 degrees. As a light source high-efficiency LED is used. The use of high-quality material used for the construction of the luminaire ensures it’s failure-free and long-lasting operation. Material housing provides resistance to weather conditions (borosilicate glass and an aluminium housing, a frame made of stainless steel). The SOBL lampa are powered by a solar panel.

The SOBL lampa are powered by a solar panel. The control system mounted on the lamp frame performs the function of obtaining energy from solar panel, battery charging, twilight sensor operation, control lamp work. The OBL lamp is built on the basis of two lamps, which ensures reliable operation devices. At the moment od detection of dusk, the control system automatically switches on one of the lamp. When a failure is found, the system disconnects the damaged lamp, while switching on the second lamp. The battery charging system has a built-in MPPT algorithm ensuring optimal energy extraction form the solar panel.
