Yeah, which is pretty meaningless because lux is a measure of light intensity at one particular spot and it doesn't provide any information about the distance at which that's measured, how big an area it'll reach that lux value over, or anything. My little 1 watt torch could probably produce ridiculous amounts of lux so long as it was only over an area the size of a postage stamp, for example.
But that's the only reference on the page.
