Using these spot lights is easy. First, make sure you have a licenced electrician install them following the instructions in the box. Connect the external control gear as required and choose a compatible power source within the 12 - 24V range. Since the globes aren't included, you need to buy them separately. When using, ensure the IP65 rating is suitable for your outdoor environment to avoid any damage. For maintenance, simply wipe the black aluminium surface with a soft, dry cloth to keep it looking good. If you have any problems within the 2 - year warranty period, you can get a replacement.
