Dear Jim,
I just picked up a Streamlight Twin Task 3C [1] from Flashlight Outlet [2]. They were set up at the Indy 1500 Gun and Knife Show [3] near my tables, and are great people to deal with.
This light is solidly machined from aluminum, small enough for use, large enough to make a handy baton, and gets 1 hour at 57 lumens of xenon bulb, 100 hours at 21 lumens of LED, and has a laser pointer. I didn’t really need the laser pointer, but it was $1 cheaper with it than the version without. It takes 3 common C cells. I plan to get
Other good Streamlight products are: This product [4] for forensics use (detecting blood/protein stains has some dark but practical uses) and this one [5] which can detect radiator coolant or HVAC gas leaks.
Another thing to consider with flashlights is that a small one, such as a standard Mini MagLite, is about the same size as a kubotan. When traveling or in restrictive locations such as schools where better weapons are not allowed, and as backup, this offers light and a way to apply force to nerve points. My kids are carrying them to school. – Michael Z. Williamson [6]
