Less than $20 for 1300 (?) lumens
For a real bargain try one of these:http://www.ledsupermall.com/tag/ultrafire+501b/
Only $18 including shipping for VERY bright (they claim 1300 lumens, but who knows) light including battery and charger. I have one and it looks to be quite well made and it is too bright to use on anything close up, it actually hurts your eyes (though it has lower output modes you can switch to).
It isn't the conditions its the decisions
