A light emitting diode linear light which is high powered and has enhanced uniformity and illumination and is safe to humans, environmentally friendly, and possesses an extremely long lifetime is disclosed. The LED lighting comprises a polygonal light pipe, a light reflector panel, two LED packages, two LED PCBs, a plurality of heatsinks, a plurality of heat pipe assemblies, a protective housing, a back cover, and a diffuser cover. The polygonal light pipe comprises a transparent or semitransparent material. A patterned surface on the light emitting surface of the light pipe diffuses the emitted light. A patterned surface on the surface of the light pipe opposite the light emitting surface reflects light. The plurality of heat pipe assemblies comprise heatsinks and heat pipes. The heat pipes are hollow pipes that are filled with a liquid such as water or coolant and cooperate with the heatsinks to dissipate heat.
