Medium Intensity Obstruction Lights

Where do we need medium intensity lights?

For aviation obstacles higher than 45 m, according to ICAO medium intensity obstruction lights must be used. The obstacles can be buildings, cranes, towers, chimeneas, High voltage network pylons, etc.

When do we need medium intensity lights?

• There are obstruction lights for use during the day and others during the night.

During the day stronger lights must be used, flashing, 20000 cd WHITE color, omnidirectional beam. This light can also be used during the night but must be dimmed to 10% so just 2000 cd. This is the type A medium intensity light.

There are other obstruction lights for use just during the night time. These are types B and C.

The obstruction light type B is flashing RED, 2000 cd. It can be used alone or in combination with low intensity obstruction lights type B.

The obstruction light type C is steady RED, 2000 cd.

What type of medium intensity obstruction lights do we manufacture?

• medium intensity obstruction light type A
• medium intensity obstruction light type B
• medium intensity obstruction light type C
• combined A/C
• combined A/B
• double B/B
• double C/C
• combined visible/infrared

These lights can have internal light sensors for day/night mode.

If more flashing lights are used on a structure all of them must be synchronized. This is made usually utilizing a controller or using GPS synchronization.

We can even integrate UPS into the obstruction lights for powering the lights if the main power supply fails.

We can create many obstruction lighting systems, with redundancy, dual input power voltages, and combined A/C or A/B obstruction lights. We can have double C type or double B type.

What options do you have for medium obstruction lights?

• internal lights sensor
• GPS synchronization
• radio controlling
• redundancy
• integrated UPS
• dual input powering voltage
• dry contact to signal failures
• IR infrared

The controllers can also be customized to signal the failures and to communicate the failures to the BMS systems.
