The Solar Obstruction Light DWS501A is a Solar Powered Aviation Obstacle Light as a FAA L-810 or ICAO Low-intensity Type B with the characteristics of solar self-contained, durable and anti-UV .It is widely used in the Aviation Obstacle Warning of Telecommunication/Power Towers,Chimneys,Cranes,High-Buildings and other dangerous Prominent Parts.

It installs in minutes and requires no maintenance or servicing for up to five years.

1.What are characteristics of obstacle lights in the standards of ICAO and FAA?

According to ICAO Annex 14 Volume Ⅰ,the characteristics of low-intensity obstacle lights are as follows.

      Light Type                 Color           Signal Type/(flash rate)    Peak Intensity(cd)    Intensity(cd) at given angles                                                                                                                                                      +6°               +10°

Low-intensity,Type A        Red                      Fixed                            10  Min.                   10 Min.          10  Min.    

  (fixed obstacle)

Low-intensity,Type B      Red                      Fixed                            32  Min.                    32 Min.          32  Min.

  (fixed obstacle)

Low-intensity,Type C       Yellow/Blue         Flashing                          40     Min.                                  

    (mobile obstacle)                                       (60~90fpm)                   400  Max.

Low-intensity,Type D       Yellow                  Flashing                          200  Min.                               

  (Follow-me Vehicle)                                  (60~90fpm)                   400  Max.

 

The Specifications for Obstruction Lights in FAA AC 70/7460 -1k can be seen in the above Table 2.

2.How to install the solar obstruction light? 

 

There are two installation methods:

2.1. Direct installation

The Drawing and Hole map of DWS501A are as follows:

 

 

 

 

2.2. With the Flangebase

The solar obstruction light DWS501A can also be connected to other structures via a Flangebase, as shown in the figure below.
