True, but I don't think the Photon Freedom is any better. According to the graphs on CPF, it drops to 40% after only half an hour. So new light is better in this respect.

Would it help to think of it as a 5 lumen light with a longish runtime rather than a 10 lumen light with a short runtime? I suppose I'm concerned that people might have unrealistic expectations, and might turn down a better light because Doug has been unusually upfront about its limitations.

The short shelf life and poor cold weather performance are also a big problem, especially for the masses who are unlikely to bother changeing the batteries on a regular basis.
Sure; I was just interested in the runtime issue.
