A test of a new model for the low-to-high (L-H) mode power threshold, based on the stabilization of edge thermal instabilities, is made by comparison with a set of DIII-D (J. L. Luxon, Nucl. Fusion, 42, 614, 2002) discharges at times just prior to a L-H transition. Agreement is found between the measured power crossing the separatrix just prior to the L-H transition and the predicted power threshold for the stabilization of transport enhancing thermal instabilities.
