Light fixtures for illumination of liquids in a variety of environments. In one example, multi-color LED-based light fixtures are employed to achieve a wide range of enhanced lighting effects in liquids. In another example, a pool or spa is illuminated by one or more multi-color light fixtures that may be employed as individually and independently controllable devices, or coupled together to form a networked lighting system to provide a variety of programmable and/or coordinated color illumination effects in the pool or spa environment. The light fixtures may have a significantly thin depth dimension to facilitate streamlined mounting in the pool or spa. Additionally, the light fixtures may be particularly constructed to take advantage of the liquid in contact with the light fixture so as to facilitate the dissipation of heat generated by the light fixture.

The apparatus of claim 8, wherein the housing further includes a back plate, and wherein the gap pad is disposed between the at least one light source and the back plate.10. The apparatus of claim 1, wherein the lighting fixture comprises at least one mounting mechanism to mount the lighting fixture to the inner surface.11. The apparatus of claim 10, wherein the at least one mounting mechanism includes at least one suction mechanism to mount the lighting fixture to the inner surface.12. The apparatus of claim 1, wherein the one of the pool and the spa has a range of typical liquid levels of the liquid during use, and wherein the lighting fixture is adapted to be disposed below the range of typical liquid levels.13. The apparatus of claim 1, in combination with the one of the pool and the spa.14. The apparatus of claim 1, wherein the lighting fixture includes at least one LED.15. The apparatus of claim 14, wherein the at least one LED includes at least two differently colored LEDs.16. The apparatus of claim 14, wherein the at least one LED includes at least one red LED, at least one green LED, and at least one blue LED.17. The apparatus of claim 12, wherein the lighting fixture is adapted to be submersible in the liquid.18. The apparatus of claim 1, wherein the first dimension is less than 2.25 inches.19. The apparatus of claim 1, wherein the first dimension is less than 2.0 inches.20. The apparatus of claim 1, wherein the first dimension is less than 1.75 inches.21. The apparatus of claim 1, wherein the first dimension is less than 1.5 inches.22. The apparatus of claim 1, wherein the first dimension is less than 1.25 inches.23.
