Using these spot lights is easy. First, have a licensed electrician install them according to the instructions in the box. Connect them to an appropriate power source within the 12 - 24V range and use external control gear as required. Since the globes are not included, you'll need to buy suitable MR16 globes with a maximum wattage of 20W. When it comes to maintenance, keep the lights clean by gently wiping them with a soft, dry cloth. Check the IP rating before placing them in an area to ensure they're suitable for that environment. If you face any problems within the 2 - year warranty period, you can get a replacement.
