Yes, the Q-III is the TM-303X and the 1W version of the Q-III is the TM-306X. The lights are identical from the outside and this fact combined with some mixup problems at Nuwai is also the source of the Q-III "seconds". Earlier this year, I learned of some Q-III's that had significantly lower output but were otherwise the same, including the 3W logo on the clip. All the Q-III's I had seen so far had the same (high) brightness. Later, milkyspit bought a Q-III from me and then contacted me about the light not being as bright as expected, even so it had the 3W logo on the clip. But there was something strange about his light: the logo on the top left of the package said 1W instead of 3W. I sent milkyspit another Q-III and checked the few I had left, and indeed, there was another one of these hidden among the 3Watters! Obviously, Nuwai has at one point mixed up 1W and 3W versions of this light. I am not sure if all the 1W lights disguised as 3Watters come in the package with the 1W logo, but the 2 I received from Nuwai were that way. So it's definitely worth looking at the silver logo on the package of every Q-III.
