GN-34 Light Bulb -Airport Lighting-Description: This is a FAA approved airport lighting xenon flashlamp in a Par 56 with a clear front lens. It is a 3 screw lug terminal design that operates at 2000 volts anode and 60 watts per flash at 2 flashes per second> OAL is 5' and OD is 7". Trigger voltage is 15-18 KV. Life is 4 million flashes. One lamp is clearly new as it has the attached tag. The other lamp is used but have been told it works. The new bulb is not marked with a manufacturer but is identical to marked Genesis bulb that is used. UPDATE: I found the box that the unmarked bulb was shipped in and it is manufactured by AMGLO KEMLITE LABORATORIES. It is a Helical Flashlamp. The box was ONLY labeled with the manufacturer.
