The same dome that halogen FB2.Hey Dan!
You briefly touched on the FBII strobe but you forgot to mention the EARLY FBII strobe w/ the dome insert versus the later, actual fresnel dome:
That is correct. They slid a fresnel insert under the standard FBII dome during the early years...The same dome that halogen FB2.
Dmathieu, are you sure that there are FB-FH with halogen bulb ?Federal Signal's 2nd Version Flash Ball was still a non rotating light like the Version 1, with some design changes.
It had the larger magnet, was available in halogen or incandescent bulb, and had a new reflector and socket design.
The reflector was still stationary. The bulb was flashed by a flasher for a directional warning.
These Flash Balls are even more rare than the Version 1 Flash Balls.
Thanks Dmathieu, if you have pics with FB-FH with halogen bulb, i'm interested.The clear is F7, in keeping with the newer version FB series, and yes, the 2nd version Flash Ball was made in both incandescent and halogen versions.
Yes, the center plug was used by Federal on later series B1 FB-1s, and newer versions FB11s.
There was also a Serial FBF F2.
Correct, mono it is.I suspect it would take a mono plug, not a stereo plug. There's just power and ground.
