  • CK-11LS Dual low intensity obstruction light Type B

CK-11LS Dual low intensity obstruction light Type B

Product Description


Widely used in various fields of the Air Force, civilian airports and obstacle free airspace, helipads, iron tower, chimney, ports, wind  power plants, bridge and city high-rise buildings where require aviation warning.

Key Feature

● Lamp cover of the light adopts PC with anti-UV which is high efficiency light transmission up to 90%, quite high impact resistance and fit the bad environment very well.

● House of the light is made of aluminum alloy and painted by spraying plastics,the structure is high strength, resistance to corrosion.

● Using Fresnel lens optical design, range further.

● Light source adopts LED with long lifespan up to 100,000hrs, lower power consumption and high efficiency.

● Based on the single chip computer automatic control, and also could be controlled by controller.

● Used the photosensitive probe fit for the natural light spectrum curve, automatic control light intensity level.

● The circuit of the light has surge protection so that the light is suitable to harsh environment.

● Integral structure, protection level of IP65.

● Ignitability rate UL-94V0, fit for all kinds of industrial situation.

● Could choose controller to control the synchronous switch function.

● Main light and standby light, it will be automatic transfer
