Yes, the 4412 is the correct sealed beam.
PAR46, 12V, 35W, 11000CP and 40x5 degree spread.
I do not know of what you mean with that you have seen differences?
You need a fog sealed beam that create a horizontal I-beam that moves up and down so you will have a distinct flash both directly in front of and at angle of the light.
