Anyone know what type of led is in these? The output is very impressive - close enough to my jetbeam cree with a standard lithium that has been used for about an 2 hours on high that I think.............this one cost $2.90 and THIS one cost $70+................I guess I can take comfort in the small size of the Jetbeam and the killer lumens on 14500. I only found 8 more at the store near me, I bought them all....there are 44 more at Fry's nearby-may pick up a few more.
