All Halcyon lights can be fitted with underwater pluggable cords. This feature allows divers to switch between video lights and conventional HID light heads. Divers using quick-disconnect cords may also swap a damaged light head while underwater. However, divers using this option should weigh the benefit against a possible increase in complexity. For example, a short interruption in the current flowing to an HID light will cause the light to falter. Shutting down the light for five seconds allows the ballast to reset. Divers that require greater flexibility are usually happy to manage the increased complexity. However, you should consider these issues while choosing the system that is best for you.
