Just to share i just got a really good flashlight off ebay for less than $16. It uses the Cree T6 LED and is super bright. It has the option to run on 4-AAA, or one 18650, or one 26650 li-ion. Right now the 26650 is not a cheap option but I hope it will be in the future, the four AAA's are very cheap and will last me a while. The seller got it to me in about 2 weeks, which is real fast from china. The wide beam is very impressive, the narrow show's the LED's die, similar to what the OP posted.
I got this flashlight because of the T6 LED and the fact that it will take 4-AAA's, there are several T6 versions out there that only use 3-AAA's and that odd number is annoying IMO. I would also like to use 26650's when the price comes down.
