ELECTRONIC BALLASTS FOR FILM & TV LIGHTING; HIGH SPEED PHOTOGRAPHY; EVENT LIGHTING AND SOLAR SIMULATION For over 25 years the ... largest rental companies and motion picture studios worldwide have chosen Power Gems to supply one key element in the lighting system used in film and TV production - the electronic ballast. Founded in 1991, Power Gems is the biggest independent designer and manufacturer of HMI ballasts. The lighting equipment uses the latest silicon carbide technology to control the arc in HMI lights, to provide the 'flicker-free' light required for location filming. Not a year goes by without a new addition to the Power Gems family or refresh of the core 20 product lines - many are regarded as workhorses of the industry. Initially developed for use in film and television production, Power Gems have been adapted for new markets: solar simulation, high speed photography and events. For many original equipment manufacturers we are the preferred supplier, helping to bring their products to market.
