A lighting system for providing a selection of different colors of light and a desired duration that the light remains on includes a light housing and a hook portion being attached together. The hook portion is configured to engage the support surface and suspend the light housing from the support surface. Each of a plurality of light emitters is coupled to the light housing. Each of the light emitters is configured to emit a color of light different than other ones of the light emitters. A globe is couplable to the light housing and extends over the light emitters. A control assembly is operationally couplable to the light emitters. The control assembly is configured to engage a power source. The control assembly controls which of the light emitters is energized and a duration the light emitters are energized.
