QTS-100-RGBW-Ti The QTS is the latest light introduction from Underwater Lights LTD. This light is the next generation of the hugely popular QT-100, with an almost identical hole cut-out but with improved optics and LED’s. The lens has now reverted to its original flat design whilst still maintaining a 140 degree light spread.

The QTS is now also made out of Titanium which is a huge step-up from the previous Aluminum Bronze material used on all other high quality lights. Titanium is incredibly hard wearing, corrosion and electrolysis resistant and offers huge benefits to customers; that they never need to worry about their housing potentially corroding out of the boat should there be a boat in their marina with a electrolysis problem. Electrolysis has historically become a huge problem and there is very little a boat owner can do about other vessels emitting harmful voltage into the water which will affect all nearby vessel other than making sure their cathodic system is fully isolated which doesn’t always help save their metallic thru-hulls.

The QTS is being positioned to be the only light you will ever need from smaller 30-40’ cruisers to the largest 300+ ‘ Superyacht. With the QTS, there are 7 different options to choose from, single colors and color changing units all depending on your budget, output desires and boat requirements.

The QTS-100-Ti underwater light fixture has a titanium face, flush mounted borosilicate glass lens and an AC powered external driver. The fixture also allows for an increase in LED power dor extra light output. The light installed in carbon fibre, GRP and Timber of 20+ (subject to Lloyds approval) Distance between the lights can vary from 1-1.5 meters on the transom and 2-5 meters port & starboard for the best illumination.

Never feel trapped by this fixture as the LED projector is designed for RGBW, white, blue or dual colour and can be easily removed for servicing and upgrades without hauling your boat.

With its 140 degree beam angle the flush fixture provides a perfect spread of light.

Lloyds Register Approval and ABS Design Approval on all components. Using the latest technology allows our underwater lights to perform well in the harshest of environments.
