Some customers have asked whether their older hot tub can be upgraded to include our latest Aurora LED perimeter lighting feature that accents our newest spas in a variety of colours. Unfortunately this particular lighting feature cannot be installed on older tubs as it requires additional electric work and adding lights to the inside of the acrylic. However we can recommend the LED Underwater disco light as a stand-alone substitute for creating a panoramic lighting experience within your hot tub. This LED disco light floats within your spa and provides a great lighting atmosphere without having to install additional packages. It works really well within our hot tubs as the silver marble shell acts as a canvas for the lights to be displayed upon.
