Using these spot lights is simple. First, find a suitable location on an exterior wall pillar. Remember, a licenced electrician must do the installation as provided in the instruction sheet in the box. Once installed, you can connect them to a power source within the 110 - 265V AC 50/60Hz range. Since the globes are not included, you'll need to buy GU10 bulbs with a maximum wattage of 35W. When it comes to maintenance, clean the lights regularly with a soft, dry cloth to keep them looking good. In harsh weather or heavy rainfall areas, it's best to protect them or use IP65 fittings instead. This will help avoid any warranty problems and keep your lights working well for the 2-year warranty period.
