Hi ,
I have an Arri 1200/575 watt electronic ballast for an HMI lamp. I don’t have the lamp head itself and would like to install a HMI bulb into a film projector lamphouse using the ballast to control the lamp. I’ve tried looking for a circuit design for the lamp ignitor but can’t find any specific information on components. I have an ignitor that should be suitable but my question is does anyone know how I would go about hooking this all up together ? Presumably I would need some sort of timer that knocks the ignitor out once the lamp is established? I realise I may encounter flicker due to the mechanical nature of the projectors shutter although I am hoping the square wave from the ballast will render this unobtrusive. Any help or advice will be gratefully received. Best wishes, Jon
