Has your Softub light gone out? A new one is $120 and must be installed by a dealer costing major $$$. This is a sensible work around your light problem. These lights are rechargeable, submersible LED lights, and they come with a Remote. They are also IP68 Waterproof and have 16 colors to choose from. The clever holders hook right to the gap between you intake and tub. All you have to do is slip it on the intake and slide it all the way back (see images).  This secures your light in a convenient spot instead of having it float to the bottom. THESE HOLDERS ONLY WORK IF YOUR TUB IS PRE 2009 WITH A  4 INCH INTAKE SEE PICTURE.
