About Us



August 2019, Sevenoaks, Kent, UK - Underwater Lights Limited has developed another market leading underwater LED marine light taking the standard for the industry to yet another level; their new QTS-100 is small in size yet powerful enough to project a brilliant 20,000 lumens of light output - enough for the largest of composite Superyachts yet compact enough for a mid size runabout.


Making its debut at the prestigious Fort Lauderdale International Boat Show this November, the QTS-100 is small in size with a low enough profile to allow it to be flush-mounted in nearly any location on the hull or transom.

The QTS-100 is available in 3 formats and is designed with a hole cut-out of 74mm making upgrading to LED technology easy and without costly hull repairs. It’s proven AB2 housing construction has been a solid performer for 27 years throughout the Underwater Lights Limited product range.

The QTS-100 Internal is the DC model which has a lumen output of 10,000 and is recommended for composite boats up to 30m/100ft. You can space each fixture between 1-5 meters/3-9 ft apart for the best even illumination as it has a standard 140 degree beam angle providing a wide-spreading light pattern preventing dark spots between fixtures. It is controlled by a standard on/off switch with a 11-28V DC power range and is available in a single color white and blue or the new dual color white/blue option.

The QTS-100 External is The AC version (110-240vac) and has an external driver which provides the brightest light output of 20,000 lumens. Suitable for vessels over 20 meters/65 feet with the same 140 degree beam angle. It is controlled by a standard on/off switch and is available in white and blue.

The QTS-100 RGBW is the full color change model available in both DC or AC. Powered via an external driver which is controlled via a DMX controller (sold separately).

QTS-100 joins an impressive line-up of underwater marine lighting products from Underwater Lights Limited including retro-fit models meaning any vessel already equipped with underwater lighting can be easily upgraded to the latest LED technology without hauling.

The complete QTS-100 range has been Lloyds certified for test and design pressures to 100 and 25 bar.

Come see the new QTS-100 and meet the Underwater Lights Limited team in the Superyacht pavillions at the Fort Lauderdale International Boatshow booth #692 and booth #10.104 at the Metstrade Show in Amsterdam.
