Think ive decided on the TK40. I could not find any other flashlight that has that many lumens (630), decent sized, and uses common AA batteries. Plus it has all the way from 13 lumens all the way up so it can be used on any occasion. Plus the strobe, which I could use often. The pelican is great but the output is weak, and I dont care for the look of it.
Sorry I didnt research before-hand, didnt think this was such a hot topic.
That's a great light, but for law enforcement - not really.
Lets face it the user interface (changing light modes) is not very tactical at all, many find it annoying. I don't need 3 different strobe/s.o.s. settings on my light, nor do I think "strobing" anyone does anything but get people's attention or simply p*** them off. Luckily, the TK40 does remember your last setting, which for me is usually high.
It's kind of bulky too, you might have a hard time finding a
quality holster for it. If you do, you might find it jabbing you all night in the squad car. Also, if you have to hold it in combination with your firearm (if you have one), that can be kind of cumbersome and draining also.
I like the AA idea for a bright flashlight, but I would highly advise
not putting cheap alkalines in it. They won't have very good runtime and eventually one will leak in your new $150 light, not good. Spend a little more money and get some decent nimh rechargeable batteries - I suggest eneloops which can be easily found.
On the plus side, it's tough as hell, very bright, and is a decent mix of flood and throw. Enjoy your new light.
Above all, stay safe
