Using these bollard lights is simple. First, make sure you have a licenced electrician install them according to the instructions in the box. You can mount them on a solid surface like a concrete path or a sturdy timber deck. When connecting the cables, use circular cable in the junction to keep the IP54 rating. For parallel or single connections, use an appropriate IP68 connector. Remember, these lights are not suitable for dimming, but they work well with 2 - way switching. They can work in temperatures from - 20 to 50°C, but avoid using them in harsh weather or heavy rainfall unless they are properly protected. If you're in such an environment, consider using IP65 fittings instead. To keep them in good condition, check the lights regularly for any signs of damage. And if you encounter any problems within 3 years, you can get a replacement as per the warranty.
