Fenix Tactical has released their TK45 – a new 760 lumen wonder flashlight. The light features three individually housed Cree XP-G LED’s mounted on a single head. This allows better heat dissipation vs. having all three LED’s in a single bezel. It also gives the TK45 a unique ‘mini-gun’ appearance (Fenix’s own term) which is something you’ll either love or hate. I’m attracted to the light’s features and am less concerned with how it looks.
TK45 is powered by 8 AA batteries to offer four levels of brightness and three flashing modes. Maximum runtime on low is 232 hours. Runtime on ‘Turbo’ (aka 760 lumens) is about 2 hours. Some flashlight enthusiasts criticize the TK45’s use of 8 regular AA batteries instead of CR123A’s more commonly used in high end lights. As a flashlight semi-enthusiast, I like the ability to go into any store or gas station and buy inexpensive replacement AA batteries.

Light Junction has a nice video review of the TK45. As you’ll see in the video, it may take some user practice to switch to the various light modes:
Retail on the TK45 is around $150.00, pretty reasonable for a high-tech, high power light. The TK45 is too big and perhaps too fragile for a personal carry or weapon light; but it would be great for search and rescue (provided you bring extra batteries), caving, off-road trailing, etc. I did have the Fenix TK40 on my wish list, but the new TK45 just took it’s place!
