Pros: Bulb Durability, Battery Life, Durability, Brightness
I got this to tuck away for emergency purposes. I have the 6P, G2, Streamlight Poly-tac and Scorpion, as well as a few other brands and have been carrying this as my main light for the last month or so to test it out, see if it's up to snuff. This light seems well made and very rugged. Been using it outdoors: shooting, fishing, backpacking, hiking and around the house. Has good grip texture in the hand and slight bezel crenelations. Not sure if it's an effective strike bezel, but it will leak light around the edges to show if it's left on while sitting upright. It's bright for its rating, about as bright as my friend's light that's rated at about twice the lumens. The low setting is good for work where high is just too bright and it conserves the battery nicely. It's a trade off with these lights. The E1B is brighter on high, but at the expense of burn time. I also like the two-stage button on the E1B better, versus having to click the E1L off and back on to get the high setting. Still, I went with the E1L. It has the longer burn time and still respectable high power. Also, note that the E1E has just one brightness setting that's kind of medium-bright that's good for most purposes.
