1. A high-power light emitting diode (LED) lamp, comprising:

  • a mounting mechanism to mount said lamp to a pool/spa or a pool/spa device;

    a removable cylindrical housing having a cavity and an open end, a groove around a perimeter of an inside surface of said cavity proximate to said open end for mounting a replaceable lens therein, said housing made of a heat conductive material;

    one or more high power LEDs disposed on a printed circuit board (PCB), said PCB mounted to said housing within said cavity using a thermally conductive bonding material such that at least some of the light from said LEDs is directed out said open end of said housing; and

    an encapsulating material substantially filling said cavity, said encapsulating material encasing said LEDs and portions of said PCB and contacting said inside surface of said cavity, said encapsulating material providing a waterproof covering over said LEDs and at least partially transmitting light from said LEDs out said opening, heat from said LEDs conducting away from said LEDs and through said encapsulating material and said housing to dissipate in the ambient around said lamp.
