Aqualuma 18 Series LED Underwater Light GEN 4



Product Description

The 18 Series is the latest edition to Aqualuma’s Thru-Hull range. Designed to illuminate the world’s largest super yachts.

A unique upgradeable and serviceable LED underwater light. Aqualuma lights are the world’s first and only underwater lights with a one-piece housing that has no lenses or seals, which means they can be serviced and upgraded without the need for haul out. Corrosion-proof and injection moulded, the thru-hull underwater lights feature Aqualuma’s patented polymer housing, the most sophisticated and strongest material available in underwater lighting. These lights are virtually unbreakable and have been pressure tested to 1300 feet below sea level. The real advantage of the Aqualuma thru-hull system is the ability to continually upgrade as LED technology advances. Many of Aqualuma’s original customers have taken advantage of this service, to stay up-to-date with the latest in advancing technology.

Bigger, best, brightest. The 18 Series is the latest edition to Aqualuma’s Thru-Hull range. Designed to illuminate the worlds largest superyachts. The 18 Series is our largest thru-hull option. Designed for large vessels and superyachts, the 18 Series delivers a huge light output at an affordable price in our patented, one piece polymer housing and has the ability to be serviced from inside the vessel. The 18 Series ultra light is encased in our 12 Series housing and gives Aqualuma 6 and 12 Series owners the ability to upgrade to the18 Series from inside the boat with no haul out.
