This Rising Dragon lighting system is used in Wellis brand spas. Its multicoloured LEDs offer six solid colours (red, blue, green, yellow, white and purple) and many light effects. The controller or the 7-LED master light connect to a 12V AC source. You can then link the selected auxiliary lighting (multi-LED spyders and/or slave lights). A splitter also allows a cascade connection.
Below are examples of possible connections (there are many!) of this lighting system, and the parts numbered in the same order at the bottom of the page.
