Sorry I missed this question earlier. Yes, the only expected difference would be in tint, with the 4C being the cool-end of Warm tints (or the warm-end of Neutral tints, depending on your point of view). Output and runtime should be the same, as the T6 output bin is the main determinant for those characteristics.Has anybody tested the m11r "premium" edition? It appears to be the same light but instead of the CREE XM_L U2 LED, it has the CREE XML T6 4C. Is the only difference the T6 4C is a warmer tint?
