    Maybe either a General Electric No.50 or Wabash-Sylvania 
No.3. These were about the size of a No.2 photoflood and 
were meant to fit into standard studio reflectors. These 
lamps are listed as having six million peak lumens. The open 
flash guide number for ISO-100 film is around 780. These 
were the most powerful bulbs made. If more light was needed 
you had to use flash powder.
    The GE No.5 or Wabash/Sylvania Press-25 was a bayonet 
base bulb, very common for both press and small amateur 
cameras.
