If you are into any type of self defense long gun, then you could probably use a weapon mounted light. Nightstick, a division of Bayco products, has brought out some nice lights in this category. One of those lights is the LGL-170. This is their top tier weapon mounted light, coming in at 1500 lumens.
Now I know that you just can’t judge a light on Lumens alone. You need the Candela rating also. Well the LGL-170 produces 23,148 candela. In easy to understand terms, the lower the candela rating, the more “flood” like the beam output will be. The higher the candela, the more “spot” like the beam will be. At 23,000 candela, I found the Nightstick to be a good combination of the two. It produces a wider beam then some other weapon lights on the market, but yet still gives plenty of throw to see down range. Nightstick rates it at a 304 meter beam distance. All I know is that I can make out targets at 200 yards with the naked eye, in essentially complete darkness. This also translates into being able to see “threats” out to 200 yards.
Nightstick includes everything needed to get started with the light. In the box are 2, yes 2, 3400mah 18650 rechargeable batteries, with a charger of course. Standard and off-set picatinny mounts. An optional 6” cabled pressure remote pad, with an on/off button. The pad can be used with a supplied hook & loop, or a slide in, picatinny rail adapter. Also for the pressure switch, is a wire management picatinny clamp. Nightstick also makes a low profile angled mount adapter for KeyMod or M-lok. I used the M-lok one to mount the light closer in toward the handguard. This makes it easy to use, with just my thumb, for activation. I thought the cable management clamp was a nice added benefit to the package, even though I ended up not using it.
In the standard configuration, the LGL-170 is your basic weapon light. The tail switch is pressed slightly to use the momentary on function. Or pressed completely to turn it on or off. There is a nice positive click when turning it on or off. One feature I really like in a weapon light, is full lumens all the time. No strobe, or low power to get me distracted under stress. The LGL-170 does this. It’s either on or off, nothing else, always at full power.
Since most of the features are listed below, I won’t go over most of them here. But, there are a couple I am going to mention. Having a way to use another power source is always a good idea. So Nightstick made the LGL able to use 2 CR123 batteries as an option. The output is cut down to 1200 lumens, but it’s way better than zero! Plus, you probably have some rolling around in your range bag, at least I do. The next feature is the light’s weight. It comes in at 7.5 ounces with the battery. It’s a little heavier, by 0.5 ounces, than some other lights, but that’s not a deal breaker. When you have a light mounted on the end of a rifle, it makes the rifle swing differently from target to target. Something I noticed when moving the rifle. Also, you just added a ½ lb to that lightweight rifle. But in this case, I’d rather have the ½ lb and be able to see my targets.
As with most products, there always has to be something questionable. The only part I really don’t like about the light kit is the picatinny switch mount. This picatinny mount, for the pressure switch, is a clip on a piece of plastic. You then slide the pressure switch into this mount. The part that mounts to the rail actually holds on okay, but could be torn off under extreme use. But even worse, is that the pressure switch just slides into the rail adapter, and doesn’t stay. Yes, I know that I could use glue or hook & loop to fix this, but it was kind of annoying. On the other hand, the pressure switch, itself, is awesome.
After a couple months of use, I ran into a problem. The light was not staying bright. After 45 seconds of being on, the output had dwindled down to almost nothing. Cycle the switch, and it would get real bright and then dim down in a minute again. I contacted Nightstick and they immediately sent a new light kit. Yes they sent the whole kit and told me to only return the light and the pressure switch. So I gained two 18650 batteries and a charger in the deal. When I asked them what had happened to the light, they said it had a programming error and were very thankful for me in helping them find the problem. Every company has something go wrong from time to time, I suspect mine was a one off problem, knowing that they have these lights in many law enforcement departments and that they have been tested by those departments. How they react to the problems is what really counts. So far, the new light is working as expected. If anything goes wrong again, I’ll update this review.
The “unrated” light output is what really shines. In my house, bouncing the light off of the hardwood floor, will literally let you see everything in the living room and kitchen, with ease. Anything you directly point the light at, is bright as day. Real world use, I did get the 1.5 hours of constant on run time. I didn’t expect the full run time at highest output, but I was pleased with how long the light was bright for. In fact, even when it nears the auto shut off from low power, the brightness was still real bright. I’d guess somewhere in the 1000 lumen range.
I can say that the Nightstick LGL-170 is a useful weapon light. It’s bright. The battery lasts a decent time and it comes with everything that you might need to attach it to your weapon of choice. I have some other Nightstick products. This LGL-170 is right up there in quality and function. If you are in the market for a weapon light or something else, that lights up your world, go check out the Nightstick line of lights.

Very well made light
The light is well made and super bright with no strobe function though ...also the mounts are very solid and screws come with thread locker applied which is a nice touch and shows some forward thinking by the manufacturer.
