Using these spot lights is easy. First, make sure you have a licensed electrician install them according to the instructions in the box. The lights work with an input voltage of 110 - 265V AC, so they can be used in many places. You'll need to buy the globes separately, and we suggest using the CLA LED globes GU1001 or GU1002. For maintenance, since they are made of 316 stainless steel and have an IP65 rating, they can withstand outdoor conditions. Just give them a wipe down every once in a while to keep them looking good. Remember, always check the IP rating is suitable for your use to avoid any problems and to keep your 2 - year replacement warranty valid.
