Using these GU10 outdoor wall pillar spot lights is easy. First, make sure you've got the right globes. We suggest using the recommended CLA LED globes GU1001 or GU1002. Since the globes are not included, you'll need to buy them separately. A licensed electrician must handle the installation. Each product box comes with an installation instructions sheet to guide them. When it comes to power, these lights work with an input voltage between 110 - 265V AC at 50/60Hz. As for maintenance, because they're made of white powder - coated aluminium and have an IP65 rating, they can withstand outdoor conditions well. But it's a good idea to check them regularly for any signs of damage. Also, always ensure the IP rating is suitable for where you plan to use them to avoid any warranty problems.
