SV10 HID 250 Watt

The Sea Vision SV10 model offers the largest aperture of all the fiberglass models giving maximum light output from the 250 watt HID metal halide lamp. It can be installed in the transom or the hull and is suitable for boats with 110-230 volt AC power, including sportfish, yachts and cruisers. The vessel must be hauled out for installation although lamp change and any maintenance can be done in the water from within the hull.

  • The 250W, HID, gas discharge lamp used in this light is not an instant re-strike lamp. This means that it must be allowed to cool for approximately 10 to 20 minutes after being shut off before being restarted. HID lamps generally require approximately 2 minutes to reach full brightness and should be left on for a minimum of 10 minutes. Failure to do so may cause the lamp to flicker when it is turned on the next time.
  • Depending upon water clarity conditions, the light beam can reach up to 30 meters (100 feet).
