AVIATION OBSTRUCTION LIGHTS :

SPECTRUM Low Intensity Obstruction Lights: For use in vicinity of airports, and on airports and air routes, to indicate obstruction which may constitute danger to aircraft.

SPECTRUM-CAT No.SIA-NEON/Single

Specification:

This aviation obstruction light is a single light unit employing a Neon Cold Cathode Helix and has been specifically designed for use where a light source with an extended life is desirable. The omni-directional light distribution is arranged so that the maximum light output obtained in the zone between 70 degrees above and 10 degrees below the horizontal with a maximum candelas at 20 degrees above.

The body is of corrosion-resistance aluminium castings finished in stove enameled aviation yellow and houses the spent-up transformer. The light source is protected by a thick clear glass dome mounted on a hinged cast ring secured to the body by means of three brass screws.

The transformer is suitable for 200/240 volt 50z and wired to connector block in a terminal box for easy mains wiring. The terminal box provided with a cast lid and gasket, and drilled for two 19 mm E.T entries; One fitted with a compression gland for circular cable and the other plugged. This is provided for straight through wiring to other lights, if required.

SIA Twin (GLS)

The transformer is mounted on the other side of a heavy gauge aluminium plate on which mounted special spring-loaded high tension porcelain sockets. The light source is plugged into the sockets and held on position by spring clips. Installation by means of a 38 mm E.T. stem and two locknuts provided on the base of fitting.

As efforts are made constantly to improve upon the design and process of manufacture of the aviation obstruction lights, the fittings supplied may differ in details from the data given herein.

Specification:

This aviation obstruction is single light unit employing a series of high intensity special LEDs, and has been specially designed for use where a light source with an extended life(approx.100000 hrs.) is desirable. The omni-directional light distribution is arranged so that the maximum light output is obtained in the zone between 70 degrees above and 10 degrees below the horizontal with a maximum of candelas at 20 degrees above.

The body is a corrosion-resistance aluminium casting finished in aviation yellow epoxy paint finish and houses the electronic circuitry for the LEDs. The light source of the aviation obstruction light is protected by a thick clear glass dome mounted on a hinged cast bezel ring secured to the body by means of three brass screws.

The electronic circuitry is suitable for 200/240V 50z and is wired to connector block in a terminal resistance and has a dielectric strength of 2.5K.V with against reverse voltages upto 1K.V.
