Matrix® Thru-Hull SeaLite®

After extensive R&D, DeepSea is proud to introduce the Matrix® Thru-Hull SeaLite®, the next leap forward in underwater lighting for boats.

The Matrix® Thru-Hull SeaLite® is an elegant combination for cutting edge technology and proven engineering. The light employs a highly thermally conductive copper alloy fitting which allows the densely configured LED’s to be utilized to their fullest potential. For heat transfer, copper is one of the absolute best materials, resulting in an LED light with outstanding light output and a very long life.

Designed with a scratch resistant sapphire crystal port and thermal cut off circuit that automatically protects the LEDs from over temperature, no details were overlooked. The standard fitting length accommodates a 3” thick hull, and an optional longer length fitting is available for thicker hulls.

The Matrix® Thru-Hull SeaLite® underwater LED light provides the peace of mind in knowing that it was designed by a company with over 25 years experience manufacturing underwater lights for deep diving submersibles, offshore oil and commercial divers.
