Abstract
A light unit assembly adapted to illuminate liquid below a liquid surface (for example of a pool or spa) includes (a) a lamp unit including a metallic housing adapted to be cooled by heat transfer to the liquid, and lamp circuitry, (b) a thermostat coupled to the lamp circuitry to control electrical energization of the lamp, and (c) a heat conductive metallic strip associated with said housing and thermostat to become increasingly heated for changing the conductive state of the lamp in response to diminished cooling of the housing by said liquid.
