I've had a CMG Infinity Ultra (single AA white LED) on my keyring for the lasy year. It is as bright as a Arc AAA Premium. Big? Well, yes, compared to the Arc AAA. But it's easy to use one handed, it's indestructable, and it stays bright HOURS longer than a Photon. I woldn't mind an Arc AAA Premium, but it is $$. Now, if one arrived under my Christmas tree, I might have to change. But until then, I'd recommend the Ultra if you want a AA LED.
