Re: Flash Lights
JETBeam BA20 270 lumen - the most useful and durable thing I've bought, probably ever. Literally use it everyday. Take it on fishing trips, boats, hikes, anytime I travel. Used it several times working on the GP. Dropped it from 3-4ft onto concrete a few times, still works perfect. JetBeam gives you extra O-rings and rubber button too. Still got my originals on and its been nearly 2 years since I've owned it.
I just use rechargeable AA+, Eneloops are the best but I just use 2400MAH+ Energizers & Duracells. Personally, I would avoid any flashlight with proprietary batteries. They will without a doubt wear out and be more expensive than some rechargeable AAs.
Best part about this light = it switches modes via rotating the bezel/head. Rather than having to half-press the button several times to get to the mode you want. Sounds like a minor detail, until you start using the light everyday. Have some other lights like that, don't like it.
Plan to get another one of these in the future to keep in the car permanently.
My dad has the mentioned TerraLux flashlight. Much prefer my JETBeam to it. The BA20 is slightly lighter weight, brighter, and switches modes at the head. And...well.. the BA20 is easier to hold in your teeth when you need too..lol.
I liked this light so much I got
JETBeams 830 Lumen BC-40 , but it ain't no pocket friendly light.
