Aqualuma has been producing underwater lighting since 2005 on Australia’s Gold Coast, with a distribution facility in South Florida. The company utilizes a patented injection-molded, virtually indestructible polymer housing that is tested to 1,300 feet below sea level. The new Gen4 18 Series features the same housing the 12 and 6 Series use, so upgrading becomes seamless. The largest through-hull option offered by Aqualuma, the 18 Series, can be serviced from within the boat. The 18 Series comes in brilliant white with 4,920 low-light fixture lumens and ultra blue with 14,100 low-light fixture lumens. There is a three-year warranty on the internal components and a six-year warranty on the housing. The lights come in 12 volt with a 2.6-amp draw or 24 volt with a 1.3-amp draw, along with 12 feet of number 2 conductor wire.
