Sure there are the well known brands like: Adorama Flashpoint, Balcar, Paul C. Buff, Inc (Alien Bees/Einstein/White Lightning/Zeus), Bowens/Calumet, Briese, Broncolor, Comet, Dynalite, Elinchrom, Hensel, Lumadyne, Metz, Multiblitz, Norman, Novatron, Quantum, Photogenic, Profoto, Speedotron, Sun Star Strobo, & Vistek,
but what other electronic flash manufacturers do you know of that most photographers in the USA haven't heard of but should know of?
