New marine searchlight developed by innovative Swedish company, ColorLight AB, is fast becoming an invaluable aid to rescue teams when searching for people and small boats in distress at sea. The ColorLight searchlight is unique in that it is dual-headed offering both halogen and UV (ultra violet) lights in one unit. Although halogen lights are sufficient during normal darkness and clear conditions, the UV light has definite advantages during difficult conditions such as rain, fog, snow, as the invisible UV beams can cut through such obstacles more effectively. In addition, fluorescent materials such as lifejackets become luminous when exposed to UV light beams.

In clear weather, the halogen light range is approximately 4,000 metres whilst the UV light range is some 1,400 metres. Remotely operated by a joystick, the searchlight can be rotated in either direction through 360 degrees offering complete freedom of movement. It features acid proof stainless steel housing for durability and is built to meet IP66 approved for heavy seas.The Swedish Sea Rescue Institution in Halmstad (Sweden) is amongst those who have used the equipment. “The range of the halogen light is more than double compared to our conventional equipment. As the new searchlight can be rotated both vertically and horizontally it means that we can be more efficient in our search operations. Another advantage is that when using UV light one avoids dazzling the other rescue team members, reducing their ability to see in the dark. The UV technique can definitely become a valuable complement for sea and rescue teams and can help save lives in darkness and during severe weather conditions,” reports Rescue Team Leader Stig Helmerson.
