Using these lights is simple. First, make sure you have a licenced electrician install them following the instructions in the box. Once installed, connect them to a power source within the 110 - 265V AC 50/60Hz range. You'll need to buy your own GU10 globes as they're not included. When it comes to maintenance, clean the lights regularly with a soft, dry cloth to keep them looking good. If you live in an area with harsh weather or heavy rainfall, it's best to protect the lights or consider using IP65 fittings. Remember, these lights come with a 2 - year replacement warranty, so if there are any problems, you can get them replaced.
