CM-13 type B Medium Intensity Aviation Obstruction Light

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.

Usually used above 45m and less than 150m buildings, could use alone, also could use with Medium OBL type B and Low intensity OBL type B together


● 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;

● Use the special optical reflector design, the visual range further, angle more accurate, no light pollution.

● Light source adopts import high quality LED, lifespan up to 100,000 hours, low power consumption, energy efficiency and environment protection.

● Based on the single chip computer control, automatic identification sync signal, do not distinguish the main light and auxiliary light, and also could be controlled by controller.

● Same power supply voltage with synchronous signal, integrate in power supply cable, eliminate the damage by error installation caused.

● 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 lever of IP65

● GPS synchronizing function is available

 Installation & Adjustment

a) Installation

●The light is horizontally mounted. Do not install the fascia diagonally, flip it, or vertically.

● When installing, make sure that the mounting plane of the light is strong enough.

●When installing, do not point the photo probe to a nearby light source and it is not blocked by nearby objects.

b) Installation Drawing 

The common installation methods of this product are two kinds of vertical installation methods and side vertical installation methods (see the figure below). 

For steel structures, curtain walls, fans, etc., it is necessary to design supporting brackets according to the specific installation position structure.

(1) Connector distinguish: The obstruction light has a cable with 4 cores, in which the brown and black lines are power supply lines (AC220V or AC110V), the brown one is Live Line (L), 

the black one is Null Line (N), the blue one is Signal Line (X), and the yellow green one is Earth Line (E).

(2) Wring instructions:

  a. When connecting one unit light, only the brown live line(L), the black null line(N) and the yellow green earth line(E) need to be connected. The blue synchronized signal no need to be connected.

  b. When connecting more than one unit light, all lines need to be connected so that the lights can be flashing synchronized.

Every six months or one anniversary, it is necessary to clean the lampshade. The cleaning requires a soft cleaning tool. A rigid cleaning tool cannot be used to 

avoid the scratching lamp cover (plastic material).


●  The lamps are packaged in a single package, and the outer packaging is made of a 5-layer corrugated paper box with a thickness of more than 5mm,

     which is protected by anti-collision,  shockproof and pressure-resistant pearl cotton.

●  Each package contains instructions for use, product certification, and factory inspection report.

●  Packaged light should be stored in an environment where there is no change in ventilation, drying and temperature difference.


● All the connections must be correct, otherwise it will damage the lights, please check the mark and instruction carefully.

● The obstruction light need to be installed below lightning conductor or lightning protection zone, in case light be struck by lightning.

● It’s normal if temperature rise while operating.

● Please do not open any part of lights while operating.

● The light is fully sealed, please do not install or dismantle unless you are professional. Once operated inappropriately, our company will not guarantee the warranty.
