I have always liked Surefire for the quality but like a lot of other people shy away from the price. I own 2 surefires a 6P and a E1B Backup and I have had both of these for 9 or 10 yrs. Recently I noticed the E1B Backup which I never use (have gone to Fenix with more output and modes) had a cloudy lens. So I notified Surefire and they gave me a return authorization and I sent it back. They kept it for almost a month and I just got it back and when I opened it something looked different. My original E1B was the 80 Lumen model and the head on the one they sent back looked different. I took it outside after dark and wow! how bright it was. Looked on their website to identify the head and it is the new EB1 Backup Duel Output 300 Lumen! So I have a brand new light that now sells for $220.00 and I paid much less for my original back in the day. So It pays to buy quality and I am more than pleased.
