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 ellipsoidal light is easy. First, connect the stage pin plug to a suitable power source. Then, insert the bulb into the fixture if it's not already in place. When positioning the light, keep in mind that the 19 - degree beam can provide a focused illumination. Since the C - clamp is not included, you'll need to find your own way to mount the light securely. For maintenance, make sure to turn off the power before cleaning the fixture. You can use a soft, dry cloth to wipe away dust. Replace the bulb when it starts to dim or stops working. Always handle the bulb with care to avoid breakage.
