Abstract

LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are flood lights. The light fixtures in at least some embodiments include power control features. In flood light embodiments beam angle and power or light output distribution can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. The light fixtures also support tilt angle adjustments and light fixture head adjustments. Beam distribution pattern can also be changed in some embodiments as well as power control. Beam distribution pattern, 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.
