You can buy a color-changing light from your dealer - Tiger Rivers are made to accept it as an option. It needs to be the HotSpring/Tiger River type, the generic ones will not fit and the voltage is wrong.
Should be less than $200 - if it's more, email me and I'll ship one to you. You can install it yourself.
$200 or less? wow my HS dealer quoted me $300 for it, but that was off the top of his head.. I understand that the IQ2020 board will pretty much control any HS accessory, so I figured that it could handle the different light options..
I am seriously considering the light, and I will shoot you an email if the local dealer quotes me over $200 on it after I make him look it up and sharpen the pencil.. I figure the project has me over $12k now and $200 more isnt gonna make much difference..
When they were installing the tub I noticed the light placement and it looked easy to replace.. I just wish the light on the waterfall would change with it.. o well.. I would still like to have different color options.. The blue is really nice, and now that I have settled into things a little more I am not unhappy with it, I just wish I had more colors hehe..
The other night I got my first opportunity to soak alone, with no kids and no wife around, and I turned off the light and the jets and it was pretty nice.. It was amazing how much of the city I could hear from my backyard.. there was a train running through town about 5 miles off and I could hear it pretty clearly.. It was kind of nice in its own way.. Now I just gotta do that at about 3 am when its really quiet..
