Using these spot lights is easy. First, get a licensed electrician to install them according to the instructions in the box. Connect them to a power source within the 12 - 24V range and add external control gear. Remember, globes are not included, so you'll need to buy them separately. For maintenance, keep the lights clean by gently wiping them with a soft cloth. Avoid using harsh chemicals. In areas with harsh weather, it's better to use IP65 fittings. This will help you avoid any disappointment and warranty problems. Always check if the IP rating matches where you plan to use the lights.
