This ellipsoidal light comes with a stage pin and a bulb, but no C-clamp. It's a great choice for stage lighting.

To use this ellipsoidal light, first connect the stage pin to the appropriate power source. Then, install the bulb carefully. When using it, make sure the area around the light is well - ventilated to prevent overheating. For maintenance, regularly check the bulb for signs of wear and replace it when necessary. Keep the light clean by gently wiping it with a dry cloth. Do not attempt to disassemble the light on your own as it may cause damage. And remember, since it doesn't come with a C - clamp, you'll need to use your own if you want to mount it in a specific way.
