**NOTE** - All underwater color LED lights from all vendors only work at 12VAC. Larger fixtures hide the transformer inside but due to the slim size of this light we ship 120V versions with a weather resistant outdoor pool safety transformer that must be installed at your house to convert 120 to 12VAC. Any light ordered as 120V will come with an EMCOD transformer included in the price. Details on this device can be found at the link below.
We also offer a smaller version designed to fit inside existing junction boxes, this version is very small, dimensions (inch): H = 1.31, W = 1.62, D = 3.4
and fits into most standard junction boxes, if you prefer the smaller internal version just let us know:
