The SeaArc 5000 is the latest addition to DeepSea Power & Light's well-established line of underwater gas discharge lighting. Designed for demanding underwater applications where durability and high efficiency are absolute requirements, this state of the art 70-watt HID fixture offers an integrated ballast for maximum reliability and is available in depth ratings of 1,000, 3,000, and 6,000 meters.

Gas discharge lighting offers many benefits over traditional halogen lighting. HID lights are typically 3-5 times more efficient (lumens/watt) than comparable halogen lights. This increased efficiency enables the SeaArc 5000 to generate an output equivalent to a 250-watt halogen light, while consuming only ~70 watts of power. The whiter light provided by the gas discharge lamp also penetrates further underwater than conventional incandescent lamps. In addition, the average 250-watt halogen lamp has a life of 2,000 hours and can experience filament failure due to vibration, while the SeaArc 5000 70-watt HID lamp has an operating life of approximately 12,000 hours and has no filament to break.

A key feature that distinguishes DeepSea Power & Light's SeaArc 5000 from similar fixtures is that the SeaArc 5000 utilizes an integrated ballast. This means that the ballast is enclosed in the light head assembly with the lamp and igniter, and as a result, only one interconnect cable is required instead of the two cable configuration that most users are familiar with when using a typical separate light/ballast arrangement. Also, the SeaArc 5000 has been designed to be cost effective for the end user by utilizing the same dome, cowl, and retaining rings as those used on the proven Multi SeaLite and Deep Multi SeaLite products.

Initial market response to the SeaArc 5000 has been very favorable. Most recently, a pair of SeaArc 5000's were mounted on a Navy MR-2 ROV used during the U.S.S. Monitor turret recovery. Feedback was extremely positive and by all accounts, the lights were a tremendous success.
