Abstract: The present disclosure generally provides for systems and methods that allow for LEDs to be effectively incorporated into existing lighting fixtures, including chandeliers and sconces. In some exemplary embodiments, the light source itself can include a heat sink disposed within a sleeve, a base disposed at the bottom of the sleeve and conductively coupled with the heat sink, an LED component disposed on the top of the heat sink, and one or more optical distributors associated with either or both of the heat sink and sleeve. For example, there can be both an inner and optical distributor, with at least the outer distributor being removable and replaceable. The present disclosure enables LEDs to perform effectively in lighting fixtures such as chandeliers where such performance was previously not achievable. Additionally, the present disclosure provides for ways to retrofit existing lighting fixtures having incandescent lights with LED modules.
