A process for hydroprocessing a distillate stream to produce a stream exceptionally low in sulfur, with total aromatics and polynuclear aromatics being moderately reduced. One embodiment of a light emitting diode chip comprises an LED and a composite high reflectivity layer integral to the LED to reflect light emitted from the active region. The method also includes holding, by the controller device, the media against the substrate in the predetermined zone to force the leading edge of the media to bend in a direction opposite the curl of the leading edge to counteract the curl of the leading edge.
