I want to get to the bottom of this old wives tale.
Do you or do you not need a crystal sync generator for a HMI light?
All of the HMI's I use have electronic ballasts.
Here is my confusion. Some sources at my college tell me that using the Electronic ballast with a non crystal sync generator will *hurt* the light and could damage the unit. Other sources say that the only negative aspect of using a non crystal sync generator is having a flicker in the light.
I've looked over the web for results and some rental companies even say that "A crystal sync generator is recommended" If it damaged their equipment they would surely not say 'recommended', right?
I am tired of mixed messages from professors and fellow students. Any help?
If the answer is that it just causes a flicker, I know that is not good, but it's better then renting a special crystal sync generator from out of state for a small student film class exercise.
Thanks in advance!
