Hilariously, Supernova warns against looking into the headlight, because they think even the standlight is dangerously bright
haha, well, I don't want to argue as I have not used an e3 myself...I have a Cyo and the standlight is about 50% of full brightness.
I also want to say that I think I lost the emphasis I was going for in my previous post - point I was trying to make was that even with a 200-400 lumen battery light, in that kind of traffic I would still want to have a 2nd blinking light in order to stand out as a bike, regardless of how weak/powerful my primary front light was. Without a blinking front light you stand a good chance of getting lost in the sea of powerful car headlights. (This is not meant to disagree with your point - if it really is less than 10% that might go over the threshold into "completely invisible to drives", I've seen some people with some cheap AA powered lights that are so weak I actually couldn't even see them as a driver until I was about 10 feet away)
