Exclusive products for Broadcasters Broadcasters working directly with JVC have access to products tailored especially for their needs. Examples are the GY-HD250LL, GY-HM700LL and GY-HM790LL, three of our most popular cameras that have JVC's exclusive LoLux feature, enabling them to capture pictures in extremely low light environments. LoLux was developed to assist television journalists when it is not possible to use external lighting. LoLux goes beyond the normal gain boost to produce broadcast acceptable imagery in the most challenging situations.
