Using this ETC Source Four Junior ellipsoidal lighting fixture is easy. First, find a suitable place to set it up. Then, connect the Edison plug to a power source. The included bulb will light up right away. When using it, make sure the power supply matches the fixture's requirements. Don't touch the bulb when it's hot to avoid burns. For maintenance, clean the fixture regularly with a soft, dry cloth. If the bulb burns out, replace it with a compatible one. Store the fixture in a dry place when not in use to prevent damage.
