This ellipsoidal light comes with a bulb and an Edison plug, but it doesn't include a C - clamp.

Using this ellipsoidal light is easy. First, find a suitable place to set it up. Make sure to connect the Edison plug to a proper power source. Since it comes with a bulb, you can start using it right away. However, remember that it doesn't come with a C - clamp, so you'll need to get one if you plan to mount it. When using, keep it away from flammable materials and don't touch the bulb when it's on as it can get very hot. For maintenance, turn off the light and let it cool down completely before cleaning. Use a soft, dry cloth to wipe the exterior. Replace the bulb when it burns out following the manufacturer's instructions.
