Background Reading: 6-R: Lighting
By law, there has to be a light in every hot tub. Some have an incandescent on/off white bulb, while others have a single-colour LED on/off, while others have a multicoloured LED bulb that has several settings. An LED upgrade package might include perimeter lighting, jet lighting, lit waterfalls, cup-holder lighting, and additional underwater lighting.
Most multicolour lights are made up of diodes consisting of the three primary colours (red, yellow and blue), and the colour changes are based on the combination of whatever colours are lit up. Sometimes one, two or all three of the colours in any given LED light fails, so it’s off synch with the other lights in the hot tub.
-Check to make sure the hot tub has at least one main light that illuminates the footwell.
-For upgraded multicoloured lighting packages, pause at each colour individually, checking each light to make sure they’re all displaying the same colour, and that there’s no dead ones.
-It’s not the end of the world if the fancy lighting isn’t working as it should. If it bothers you, you can deactivate the problematic daisy chain altogether and consider it an expendible feature.
