Fenix LD01 and TK40, although I use the TK40 every day at home and work. Best light I own, my buddy has the TK45 but I can out shine him on the throw only, other than that his is brutally brighter than mine but he can't drop to using 4 AA batteries like I can. I get several days of work running it in turbo, it vary rarely leaves turbo mode at 630 lumen.
