They claim it is equal to 10 watts halogen. It's not, that's just ad copy. If you put a light meter up against the lens you can get a high reading, but the beam is narrow and hard to ride with. A 10 watt halogen puts out a lot more light and has a much wider pattern and is much easier to ride with. There are many examples of similar claims in the "light selection guide" thread. The first post has links to beam comparison photos of many similar lights. One of the main reasons of the thread and the beam photos is to help understand silly claims like that. Don't take my word for it look at the beam photos.
