Why two-stage lights make sense for cops

With a simple push of the tail-cap switch, an officer can go right into tactical/control mode with the same light.
If you make a thorough examination of the high-intensity hand-held lights on the market, you’ll discover:

* There is a difference in features and quality among lights;

* Those differences will be important to you in proportion to how far from “normal patrol” or “normal investigations” your job is; and

* There is so much competition these days in the kinds of lights that most of us need most of the time that you won’t be at a severe disadvantage with almost any light from a quality manufacturer. 

High-quality lights are becoming, like knives and to an extent even guns, common and inexpensive. (OK, so guns aren’t all that cheap.)  In other words, if you stick to the major quality manufacturers, you’ll wind up with somewhere between a perfectly serviceable light and an exceptional piece of engineering. 

But as the competition heats up on the mainstream lights, there is a new class of light on the market that makes real sense:  Two-stage lights. Two-stage lights have two levels of light output, usually high and low (for example, 60 lumens and 3 lumens) or high and medium (100 lumens and 10 lumens, for example).

(Actually, Surefire introduced two-stage lights several years ago, but these were more for recreational activities than law enforcement, and in any case, they now have several two-stage models, some very serviceable for police officers. Of course,  other manufacturers are bringing similar models to market, too.)


Three two-stage lights in the close to the “original” size, top to bottom: Blackhawk’s Duo PKL-6, Surefire’s U2, and Streamlight’s Night Com.  All run on 2 CR123 batteries.
Why do two-stage lights make sense?  Well, consider that even your basic 2-CR123 battery, 6 volt, 60 lumen light is usually too bright to read and write by (remember the glare when you write a citation or examine a glossy drivers license with one?).  Also, if you are searching for an extended period — say an automobile inventory search or an apartment drug search — then the bright light can become aggravating, and maybe even exhaust the light’s batteries before the search is over. 

Remember, these super-bright lights were designed as subject control tools as much as anything else; they were designed to put out uncomfortable levels of light! Today, 100 lumens isn’t an uncommon amount of light to carry on your belt. That’s definitely too much light to reflect back into your own eyes, or to do routine tasks with!

In addition to the 60 or 100 lumen light on my belt, for years I've carried a 30 or so lumen LED light in my kit. In a tactical situation, I want my bright light…but when we have to spend two hours searching a subject’s apartment for the drugs we came for, the smaller light is much better. You certainly have analogous situations that on your particular job. The problem, though, is that A) two lights is twice as many to schlep around as one, and B) when you need your “other” light, it’s usually somewhere else. A light that performs both functions in the same physical package can solve both problems. 

I know: there are  many that will say that having redundant lights is better than having a dual-function light in a single package (the one is none, two is one argument), so let me address the subject of back-up lights now. Yes, I believe in them.  My back-up light is in my kit, and it’s a more powerful light than my belt-worn light…because, not being carried on my person I have no size constraints for it. 


Three “slimline” two-stage lights, all requiring 2 CR123 batteries. left to right: the Surefire L2 Lumamax, the Blackhawk Ally PL-3X, and Surefire’s A2 Aviator.

It’s not on my person like my second gun is because: 1) I already have too much stuff to carry, and; 2) Unlike a soldier in hostile territory, any emergency or tactical use I have to make of my primary light is very likely (albeit not certainly) to be of pretty short duration. 

If my light was really close to losing power, I’d already know about it from the light output itself — and have fixed it with the spare batteries in my kit, which I also carry.  Yes, my light could break, and that could be bad, but high-quality lights are pretty reliable.  Besides, see #1 just above.  It’s a trade-off, like all equipment decisions are.  It’s my trade-off, anyway.  Here’s five two-stage lights that you may want to consider.

Surefire L2 Lumamax


Three two-stage lights with momentary-on, tail-cap, two-stage switches: Blackhawk’s Duo PXL-6, Surefire’s L2 Lumamax, and the Surefire A2 Aviator.  All models go constant-on with a twist of the tail-cap.
