Every decade or two a quantum leap occurs in ideas and technology that sets the stage for years to 
come. While most are content to follow the leader and add a feature or two, a few innovators take the 
lead with revolutionary advancements that redefine the future state of the art.
Paul  C.  Buff,  Inc.™  has  a  track  record  for  such  innovations,  first  in  1986  with  the  forerunner  of  the 
modern  self-contained  studio  flash  –  White  Lightning™  Ultra.  Then  again  in  2001  with  the  first  full 
featured affordable-yet-professional monolight for the new masses of young digital photographers – 
the colorful little light that could – and did – AlienBees™.
We are now pleased to present the most advanced integrated studio flash system ever conceived – at 
any price, with performance and features far beyond any “Professional” monolight. After two years of 
intense design, evolution, blood, sweat, and tears, welcome to the brave new future of studio lighting 
-  Einstein™,  and  the  companion  Cyber  Commander™  extreme  integrated  wireless  control  system. 
Proudly designed and manufactured in America.
