In answer to Penguin - Maybe it's just me but I thought the old Infinity Ultras were a kind of perfection, like the Arc AAA. It was about as bright as you can reasonably drive a 5mm LED (up there with the Dorcy 1AAA and the Arc AA/AAAs) - which is about twice as bright as the Recon. It was a small envelope for a 1AA light while the Recon has (I think) and ungainly head size for not much light. The front twisty was well sealed, smooth, and well protected from accidental turn on, and it had good run time. It was basically just rock solid and perfectly functional. Now it's become a big Sonic, which I like less, while the Recon seems to be to be a big, ungainly, and dim Sonic.
