I've have several LED and NON led flashlight
Streamlight Twin Task 2 Lithium.
SurefireE2D.
Coast V2 Tactical.
it all depends on what you are looking to use the flashlight for..
1) Brightness (Eg Tactical uses, like blindling).. go for Surefire all the way
2) Mixed uses (Eg some bright, and normal uses) for the Streamlight
3) Normal uses (Ed just normal uses) go for the Coast..
Here are my observations
1) Lumen rating aren't worth the paper they are printed on .. to many differnt methods of calcualtion (Eg the Streamlight is 72, Vs the Surefire 60, and the surefire kicks the Streamlight's ButT for brightness and distance)
2) What goos is a flashlight that only lasts 90-120 mins?? again deepends on the uses, in the case where I use the Surefire, I always carry a tiny streamlight LED backup ( 1/2 inchs by 1.5 Inch)
3) Batteries and availability may be an issue (Eg the Coast uses 3xAAA while the others all use more expensive and harder to find 123A's)
4) Don't be afraid to wait until you can compare them hands on, and side by side..
5) I prefer the tail cap switch (with momentary on-off) but thats a personal prefrence..
6) Check out the candelpower forums (
www.candlepowerforums.com)
7) the cheap LED flashlights are just that.. cheap (Read: you get what you pay for)
Good luck..
