In addition to the two flashlights on my person and the three within arm's reach in my laptop bag as I type this, I have no less than nine flashlights in the BOB I keep in my car: Two SO-LEDs (one red, one white), two fauxtons, another keychain coin cell light, two Fenix E01s, an Energizer headlamp, and a Fenix P2D 1x123 flashlight, with an L1D (1xAA) body. I also have a red filter and a white diffuser for the P2D. Not to mention twelve CR123A batteries and twelve Energizer Lithium AA batteries.

I'll run out of food and water way before I'll run out of lumens.
