Using your PINTO 33 Pendant Light is easy. First, find a suitable place on your ceiling to install it. Make sure to turn off the power before installation. Once installed, turn the power back on and screw in the bulb into the E27 socket. When using, keep it away from water as it has an IP20 protection degree, which means it's not suitable for wet areas. For maintenance, clean the chrome - plated steel enclosure with a soft, dry cloth. You can use a mild glass cleaner to clean the glass parts, but make sure to dry them thoroughly after cleaning. Always refer to the downloaded instruction manual if you have any further questions.
