The Sea Vision SV37 Plasma weld in model for aluminum hulls can be installed in the transom or the hull, it utilizes a light emitting plasma (LEP) light source and 110 or 230 volt AC power. LEPs are the next generation of high intensity lighting. Sea Vision has adapted this technology to become the successor to their metal halide line of underwater lighting for mega yachts. The lights can be welded at adjustable angles to suit all hull shapes. The hull shape and positioning will dictate the angle of the light you require, angles available are 0 to 50 degree.
