1. A Light Emitting Diode (LED) light fixture equipped with a cooling system, comprising:
a light fixture housing; at least one LED lighting module within the light fixture housing, wherein the at least one LED lighting module comprises a heat sink, a Printed Circuit Board (PCB), LEDs affixed to the PCB, and a lens covering the LEDs; wherein the light fixture housing comprises an opening for the lens of the at least one LED lighting module; at least one driver within the light fixture housing and electronically coupled with the at least one LED lighting module; a power input interface electronically coupled with the driver; a cooling system comprising a watertight liquid cooling manifold within the light fixture housing, wherein the liquid cooling manifold comprises:
a liquid intake fitting and a liquid expulsion fitting;a first transport conduit with a proximal end and a distal end, wherein the liquid intake fitting is positioned at the proximal end of the first transport conduita second transport conduit with a proximal end and a distal end, wherein the second transport conduit is aligned parallel with the first transport conduit such that the proximal end of the second transport conduit is at a same side of the liquid cooling manifold as the proximal end of the first transport conduit, and the distal end of the second transport conduit is at a same side of the liquid cooling manifold as the distal end of the first transport conduit, and wherein the liquid expulsion fitting is positioned at the distal end of the second transport conduit; andtwo or more liquid cooling conduits connecting the first and second transport conduits so that liquid entering the manifold at the liquid intake fitting travels through the two or more liquid cooling conduits to the liquid expulsion fitting, and so that liquid entering the manifold at the liquid intake fitting travels a same distance to the liquid expulsion fitting via any of the two or more liquid cooling conduits; wherein the light fixture housing comprises an opening for the liquid intake fitting, and an opening for the liquid expulsion fitting; and wherein the liquid cooling manifold is arranged so that when the liquid intake and liquid expulsion fittings are positioned at corresponding openings in the light fixture housing, the at least one liquid cooling conduit is in thermal communication with the heat sink of the at least one LED lighting module.
