This, :twothumbs
This is my all around "go to" light. It gets carried daily at work, and when I'm not at work it sets at a convenient spot in the house, to be used for
whatever I need a flashlight for.
It has a Nailbender XML2 High CRI drop-in. Modes are: moonlight, low, medium, high, with memory. It has a smooth reflector, L2 tailcap, s.s. bezel, and a Panasonic 3400mah 18650 inside.
It has a level of light for whatever task needs done, long run times, tail stands, and it is waterproof. ( I dropped it in a muddy trench once with two feet of water in it. Thankfully, it was on at the time, so my partner just picked it up and handed it back to me). One of many times it's been dropped, usually on concrete from shoulder level.
I own a 6P, G2, C2, E1e, and E2e, but this is the one that gets used for just about everything, it gets used hard and I don't feel as guilty as I might abusing my Surefires. Also I don't get the runtime with the Surefires, if they were 18650 ready it might be different.
I had a bulletproof Solarforce L2M before this, I gave it to my brother who works construction also and it's still going strong. I liked the L2T format better.
This light works everytime, it hasn't let me down yet so it's the one I grab for just about everything.
The only negative aspect is the size. If I need to carry something smaller though, I'll just grab my s.s. E05 or upgraded E1e.
