Underwater lighting solutions

For applications where the electrical systems will be submerged for extended periods of time, the assemblies need to display certain properties that are very specific to the application. Most notably, the sealing rating has to be extremely high, as water ingress could put technicians at risk, as well as the electrical equipment.

Long immersion

For applications where the systems will be submerged for extended periods in water, the minimum IP rating required is IP68. IP69K rated products will protect against water ingress even when the equipment is subjected to high pressure jets of water coming from 360°, guaranteeing the safety of your staff and equipment. This is critical, as a faulty connector dropped into a fountain could create an electrocution risk for anyone that comes into contact with the water. For these types of situations, there is no space to negotiate, the highest degree of safety, and consequently of sealing, will be highly recommended.


The ideal choice will therefore be a plastic connector that is easy to mate and unmate, and robust enough to be submerged in water for extended periods of time. Ideally, an overmold cable assembly will provide higher water-resistance, and if the installation is outdoors, resistance to UV exposure is also important.
