Using your Helford wall light is easy. First, find a suitable outdoor spot like your front door, garage, or fence. Make sure to choose a dimmable bulb if you want the dimming feature. The lamp operates at 230V, so ensure your electrical setup can handle it. Since the cable isn't replaceable, be careful when installing. As for maintenance, the brass material is weather - resistant, but you can gently clean it with a soft cloth every once in a while. Avoid using abrasive cleaners as they may damage the brass or the frosted glass. Remember, this lamp isn't suitable for direct mounting into insulation. And with its 15 - year warranty, you can enjoy peace of mind while using it in your outdoor space.
