Abstract: A slim LED light includes an LED package substrate, two electrically conductive elements, and an extraction seat having a first light holder main body, a second light holder main body and a connection member integrally connected between the first and second light holder main bodies. The first light holder main body has at least one insertion slot as a first insertion slot. The second light holder main body has at least one insertion slot as a first insertion slot corresponding to the insertion slot of the first light holder main body. The LED package substrate can be inserted into/extracted out of the cooperative first insertion slots of the first and second light holder main bodies. When fully inserted into the first insertion slots, the LED package substrate is electrically connected with the electrically conductive elements. The LED package substrate can be easily replaceably installed on the extraction seat.
