I can't. However, I seem to recollect there was a thread here on Autogeek when the Flex light first came out in which people were discussing lumens and all sorts of opinions about it were expressed. I couldn't make head or tail of who "won" that discussion (i.e. whether it would work or not) and I decided to buy one to see. I have 3 white vehicles and one silver vehicle (also a dark blue, but that is a different matter). The Flex light really let me see what the condition of the light colored paint was (it was more or less obvious on the blue one<g>).
I was pleasantly surprised at how effective it is. I have a lot of flashlight type products here and I really didn't expect this one to be more effective than others, but it was even though it is far from the brightest. The light's objective lens is a magnifier which may have something to do with it.
