This ETC Source Four 750 ellipsoidal light comes with a bulb and stage pin, but no C - clamp. A known issue is that the C - clamp is not included.

Using this ETC Source Four 750 ellipsoidal light is easy. First, connect the stage pin to the appropriate power source. Since it doesn't come with a C - clamp, you'll need to use your own if you want to secure it. When it comes to maintenance, regularly check the bulb. If it burns out, replace it with a compatible one. Also, keep the light clean by gently wiping it with a dry cloth. Just be careful not to touch the bulb directly with your hands as the oils can damage it.
