[QUOTE="Eyelight, post: 316640, member: 24753"] I'm more or less just listening to this thread in an effort to learn more about modern lights. But seems to me there would be a number of variables that would be difficult to control when comparing one flash unit against a different brand/model. And seems the testing would need to be in a room without any reflective surfaces, if the aim is to test only the power output of the light. A flash going off is like a sneeze. The bulk of the light may go in one general direction, but light goes everywhere, bounces off everything within range. Seems this would be accentuated by tight quarters and a short test distance. But this is mostly my imagination, which as we know can wander off in odd directions at times. [/QUOTE]
