The L2 was the first real light I bought. Before my L2, the only thing I knew of good lights was a nice Mag. Therefore, I will always have a special place in my heart for the L2. That being said, I sold mine in favor of an A2 (I'm a hypocrite, I know). I'm a pilot, and my L2 was frankly too bright, even on low, for the cockpit. I love my A2, but I find myself missing my L2 at times. The wall-of-light the L2 is famous for is beyond words. you must see it to believe it. It does in fact let out a small whine on low. Not normally noticeable. The only time it ever bothered me was when I tried to use the L2 to read by, when it was quiet. Otherwise, not an issue.
If you don't need throw, and you want a TON of light, you will love the L2. I've decided to recreate my L2 by getting a KL4 head for my E2e body and a 2 stage tailcap.
Good luck in your search, and let us know if you decide to get one.
