OK it’s not got every light available on it, but it’s a pretty good indicator for most current commercially available lights. I particularly like the beam comparison graph at the bottom which shows the spread and shape of the light beam as well as the Lux level at 2m. For instance, comparing a £20 ebay special vs the Gemini Duo, you can see that at the centre of the beam they are equally bright, but the cheapo light has very little spill and is an exceptionally narrow beam.
Oh, and as I’ve just found out (after initially criticising the pictures being taken on a bend) that if you hover over the centre line in the beam shot pic, you can then drag it each way with your mouse to see more or less of each beam pattern you’re comparing!
