I suggest having a friend ride your bike with all of your lights on while you follow behind in a car. Lights may seem adequate when looking at them on a bike leaning against a tree but when it's on the road and surrounded by traffic the picture is very different.

A good example of a bright light that, in my opinion, does not cut the mustard on the road is the Radbot 1000. Looks good when you stare directly into it's bright narrow beam - walk a few feet to one side and you can barely see it.
