I just bought a JETbeam 3M XML (2 cr123) and a BA20 (2 AA) and they're incredible. The 3M is advertized as 450 Lumen and it is brighter than my Inova T4, Surefire 6PX pro, Streamlights C4 stinger and SL20. The BA20 is extremely light and significantly brighter than my Inova T4, and about on par with my 6PX pro. The 3M was $85 and the BA20 is $40. Money incredibly well spent. Given the quality of these, I would not hesitate to try 4Sevens, Fenix and COAST Wanna kill these ads? We can help!
