While all our lights come with a five year warranty, they are built to last much longer with an LED lifespan of at least 50,000 hours.
Yes, our lights are completely watertight when submerged from cold and also when submerged hot (causing negative pressure). Every lamp leaving our UK manufacturing facility is pressure tested to confirm seal integrity, backed up by our five year warranty.
We carefully select the LEDs for each product / range depending on a variety of different factors including physical light properties, thermal performance, and prodicted end-user application. We use advanced simulation software, coupled with endless real-world testing, to ensure the perfect balance of lighting performance versus LED longevity and product reliability and robustness. In some instances a light will support use of 11W LEDs, while other lights might be better suited to a greater number of lower power LEDs. Often we will use a combination of LEDs in any one lamp to achieve the best performance and distribution of light, albeit always at the same 5000K colour temperature, to ensure a perfectly homogenous and even beam pattern.
