These MR16 exterior wall pillar spot lights are easy to use. First, make sure you have a licenced electrician install them as required. Connect them to a power source within the 12 - 24V range and use external control gear. Since the globes aren't included, you'll need to get suitable ones for the MR16 lamp holder. To keep them in good shape, regularly check for any signs of damage, especially after bad weather. If there's any problem, you can use the 2 - year replacement warranty. Always ensure the IP65 rating fits your intended use to avoid disappointment and warranty issues.
