I've tried quite a few, including:
- smj modded solitaire
- Fenix L0D CE
- Fenix L0D, Seoul modded.
- Jetbeam Jet-u
- Liteflux LF2
- Lumapower Avenger (very brief, have not had a chance to do a thorough test).
Overall, I like the Fenixes for EDC. I EDC an L0D CE, but the seoul modded LOD gives great flood with better efficiency than a jet-u. I have used, but no longer use 10440 in the Fenix (just not comfortable overdriving stuff that much).
Liteflux is great in features, but I found it buggy and never trusted it fully.
Jet-u is nice but switching a bit unreliable and too floody for me. Not as effiecent too.
The Lumapower I just got. It's too big for me to EDC, but I like the clicky. I have not had a good chance to get to know it yet, so will reserve comment. Overall, a nice light that works well with 10440 tho.
Have not had experience with arc etc., but those are no-nonsense designs that generally work very well. Not fancy, but they just work.
