This ETC Source Four ellipsoidal light comes with a stage pin plug and a bulb. Note that a C - clamp is not included.

Using this ETC Source Four light is easy. First, connect the stage pin plug to a suitable power source. Then, insert the bulb if it's not already in place. When using it on a stage, you'll need to find your own C - clamp to secure it. Keep in mind that the light should be used in a well - ventilated area to prevent overheating. For maintenance, regularly check the bulb for signs of wear and replace it if it starts to dim. Also, clean the light fixture gently with a dry cloth to keep it looking good and working properly.
