Here you see a Philips-Idman type 7A Double Lamp Aircraft Obstruction Light, designed for marking structures Buildings etc, which could be a danger to Aircraft in Flight and on or around a Airport, this Light uses 2 x 80 watt Mercury Vapour Lamps and has a Integral Ballast & Capacitor as well as a Change over Relay which switches from the Mail Lamp to the Standby Lamp in the event of the 1st Lamp fails. I just need to get 2 80w Mercury Lamps to test this Light.

Fluorescent and low pressure sodium are best!
