Using these GU10 exterior wall pillar spot lights is easy. First, find a suitable location on your exterior wall pillar. Since globes are not included, you'll need to buy the recommended CLA LED globes GU1001 or GU1002 and screw them into the GU10 lamp holder. But don't forget, only a licenced electrician can install these lights. You'll find an installation instructions sheet in the product box to guide the process. When it comes to maintenance, because of the IP65 rating, they can withstand some dust and water, but it's still a good idea to clean them occasionally with a soft, dry cloth. To keep your warranty valid, always ensure the light's IP rating matches where you're using it.
