Using these GU10 copper exterior wall pillar spotlights is a great way to light up your outdoor areas. First, find a suitable location on your exterior wall or pillar. Since the globes are not included, you need to purchase the recommended CLA LED globes GU1001 or GU1002 and screw them into the GU10 lamp holders. Remember, a licensed electrician must handle the installation. You'll find an installation instructions sheet in the box to guide the process. For the best results, ensure the input voltage of your power source is within the 110 - 265V AC 50/60Hz range. As for maintenance, due to the IP65 rating, these lights are quite durable against dust and water. However, you should occasionally check for any signs of damage or loose connections. Also, to keep your warranty valid, always make sure the product's IP rating matches your intended use.
