Abstract: In one aspect, luminaires are described herein enabling independent thermal management of driver and LED assemblies. For example, a luminaire comprises a driver assembly vertically integrated with a LED assembly, the driver assembly comprising a driver heatsink having an interior in which a circuit board assembly is positioned, and the LED assembly comprising an array of LEDs and LED heatsink, wherein a barrier is positioned between the driver heatsink and the LED heatsink, separating convective cooling of the driver assembly from convective cooling of the LED assembly.
