Using your Access Lighting Sienna Three - Light Bathroom Vanity Lighting Fixture is a breeze. First, make sure to turn off the power at the breaker before installation. Since the lamps are not included, you'll need to buy A - 19 type bulbs with an E - 26 base, each with a 60 - watt capacity. Install them carefully into the fixture. You can adjust the lighting brightness according to your needs using a TRIAC dimmer as it's dimmable. When it comes to cleaning, use a soft, dry cloth to wipe the steel fixture and glass shades. Avoid using abrasive cleaners as they can scratch the surface. The fixture is rated for damp locations, but don't expose it directly to water. If you notice any issues with the electrical components, turn off the power immediately and consult a professional electrician. This fixture is UL - listed, so it meets safety standards in the US and Canada, but always follow basic electrical safety rules.
