My two favorites are the L2 and A2. I think of both lights primarily on the low level with high if I need it. The L2 on low will take care of almost all the general light needs I have. I also can not express how accustomed I have become to having the L2 (or A2 or old style L1) around my neck and having instant access to one handed, two levels of light. I commonly have the light on low, using the lanyard only, then grab the light and hit the button for a brighter, more directed blast if needed. I am no longer an LEO or in the military and my needs are more general and 'civilian' these days, but if I could have one and only one light I would have a brain cramp trying to decide between the L2 and A2.
I was raised on cheap 2 D cell flashlights, used the old angle head flashlight in the US Army, so I get a kick out of hearing how 'big' the L2 is. I do like the E1L, ArcAAA, my 5 led Peak AA. But the L2 has a really nice feel or balance and I love to use it. I have the square sided model and when I heard they were changing it to a rounded version I bought another square one and put it away. I like it that much.
The beam on my two L2's is absolutely perfect, I can't imagine a more perfect light. The only nitpick I have is the price. But then again, nothings perfect.
