I know for a fact that uniformed officers in New York are required to carry duty flashlights while on-duty. There's even a list of requirements. Ever wonder why so many NYPD officers used to carry black Maglite 2C incandescent flashlights? It was the cheapest model that met all of the NYPD's requirements for a Duty Light. Officers are technically issued their lights, but in reality have to pay for gear out of their own pockets.
Just amazing that some of them were walking around without required gear, such as their flashlights. But not surprising.
My cousin's son graduated from his state's police academy six or seven years ago. All of the municipalities he interviewed with during training required the officer obtain and carry a duty light, paid for by the officer. My graduation gift to him was a Fenix TK09, which is a 6P-sized light designed for law enforcement use (24,000 candela, 900 lumens, three modes [H-M-L] starting always on high). Everybody else in his training class of 27 men was using a Maglite 2D or 3D, most with incan bulbs, a few with upgraded drop-in LED emitters that pumped out 120-130 lumens. He told me that during his first night operations training session, the training officer was explaining the coordinated use of a light and duty weapon. When my guy's turn came, he clicked on his TK09, whereupon the training officer was heard to exclaim
"Holy s**t! That thing's BRIGHT!!! (The instructor later asked where he could get one, too. Apparently his old
Streamlight was on its last legs.)
Later, during his first year of service, he told me of a time when he pursued a theft suspect into a junkyard. The suspect was hiding behind a junked car. The TK09 lit up the junkyard, and without much in the way of shadow to hide in, the suspect surrendered without a fight.
In that line of work, good quality, reliable gear is worth paying for.
