Actually, this thread has given me an "aha! What a dope I've been" moment. Yes, those moments are happening more and more frequently these days, much to my chagrin.
I've been using my Photon Freedom around the house a lot. I'd sworn off Photons due to hating to buy coin cells, but bought this one with the idea that: it's got several levels, and since I'll normally use a low level, it'll be centuries before I need to replace the battery. It's turning out to be exactly as expected -- of the 9ish levels, I'm normally at 5 or below.
Philosophically, it's always bothered me that you only get 40 minutes of incandescent with the A2. On the other hand, with LEDs on the same light, I'd bet I wouldn't be using the incandescent very often. The A2 is probably a great fit for me.
Unfortunately, this realization comes too late. I'm guessing that by the way things are going, by a year from now, we'll have luxeon lights that are as bright and have just as much throw as the A2, with multiple levels. No reason to buy a hybrid today, when an LED will be able to do it all tomorrow.
