Number of Lights

Number of obstruction lights to be placed on tall structures can be calculated by the following formula –

Number of Lights = N = Y/45

Where Y is the height of the Obstruction.

Light spacing = X = Y/N <= 45m

There should be atleast 45 meter gap between two obstruction lights installed on tall structures.
