DCFirst Claim
1. An LED light base assembly, comprising:
- a driver housing including a base portion including a control knob opening in a wall of the base portion;
an LED driver assembly including a potentiometer;
a seal;
a dimming control knob including a shaft portion, said seal being positioned between a rear side of said dimming knob and a surface of said wall of the base portion of the driver housing, said shaft of said dimming control knob being in physical contact with a rotatable control of said potentiometer, said seal providing a water tight seal between the dimming control knob and the surface of said wall of the base portion of the driver housing; and
wherein the driver housing base portion of the LED light base assembly includes a top portion including a flat surface, said flat surface including a top opening through which at least a first wire extends, said first wire being coupled to said LED driver assembly; and
an insulating film covering a top portion of said LED driver assembly, said insulating film being positioned between a bottom surface of the top portion of the LED driver housing and the top portion of said LED driver assembly, said top portion of the LED driver assembly facing toward the bottom surface of the top portion of the LED driver housing.

Abstract
LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.
