Using these Horus bollard lights is easy. First, find a solid surface like a concrete path or a sturdy timber deck to mount them. Remember, a licenced electrician has to install the lights, and there are installation instructions in each box. When making the connections, use circular cable in the junction. For parallel and single connections, it's best to use an appropriate IP68 connector. These lights work well with 2 - way switching and can be paired with PIR or Microwave sensors. But they're not suitable for dimming. As for maintenance, since they're made of anti - corrosion materials, they're pretty durable. However, if you live in an area with harsh weather or heavy rainfall, it's better to choose IP65 fittings instead. Make sure the IP rating of the product matches your intended use to avoid any warranty problems.
