All of Wagner's sealed beams are junk. So are Sylvania's, and Eiko's, and most of GE's. The only readily-available sealed beam in the 7" round size that's worth using is this one. It is nowhere near the world's greatest headlamp, but it is the only 7" round headlamp that is both very cheap and passably decent. Step up from there is these lamps (specifically) with a set of these bulbs (specifically).
