Using these MR16 exterior wall pillar spot lights is easy. First, make sure you have a licensed electrician install them as required. Connect the lights to an external control gear and use an input voltage between 12 - 24V. Remember, the globes are not included, so you'll need to get them separately. For maintenance, simply wipe the lights with a dry cloth every few months to keep them looking good. Since they have an IP65 rating, they can withstand some outdoor elements, but avoid using them in areas with extreme weather conditions. Always check the IP rating is suitable for your intended use to ensure the lights work well and to maintain your warranty.
