just bought a 2.5k desisti leonardo fresnel HMI light and a lightmaker electronic ballast (combo 2.5/4k). its my first HMI but i have lots of experience with tungsten lighting, having 10 Mole lights.
was looking for advice on general use/safety precautions specific to using a HMI vs tungsten.
also after installing the bulb, connecting head to ballast, ballast to power, turning on ballast, i hit ignite , nothing happens, any ideas? there is a fuse on the ignite circuit but it checks out of with a continuity meter.
also there is 2 switches on the back of the head, any idea of what they do? they just have a ON (I) and off (O) labels on them.
