I started this so maybe I can end it.

First of all how bright the sun is most definitely is not the point. The point is how bright is the LED device vs. other objects illuminated by the sun. This is very different.

My initial reaction was on a very cloudy late afternoon coming out of a dark garage and 'simulating' the positions of two vehicles facing each other in left turn lanes. I found what I saw to be somewhat alarming. I ended up buying a lower power unit that (surprisingly) is not that much dimmer in strobe mode.

I've done more experiments and this really is primarily a low light (dusk, dawn, very cloudy) issue. If I had it to do all over again I probably would not have purchased the lower power unit and would simply take some amount of care to point my 650 a bit down (like you would at night anyway).
