This ETC Source Four 750 ellipsoidal light comes with a bulb and a stage pin. It's a great choice for stage lighting. One thing to note is that it does not include a C - clamp.

Using this ETC Source Four 750 ellipsoidal light is easy. First, connect the stage pin to the appropriate power source. Then, install the bulb if it's not already in place. When using it, make sure the light is positioned securely, though you'll need to provide your own C - clamp for that. As for maintenance, keep the light clean and check the bulb regularly for signs of wear. If the bulb burns out, replace it with a compatible one. Avoid using the light in wet or extremely dusty environments to extend its lifespan.
