Prevent Light NDs With A One Hundred Concepts LightCap

When I was introduced to the One Hundred Concepts LightCap, part of me questioned why anyone would need it. After all, just keep your hand and finger away from the switch on your weapon light.

Then, I took some low-light house-clearing classes from Tremis Dynamics.

Boy, did I find out that fighting in daylight sucks… but fighting at night is way worse.

The last thing you want to do when clearing a home is have light discharges that would reveal your position. Even when running night vision and IR, illuminating a room with a white light or IR light when you don’t want to is a terrible situation.

This LightCap is designed to prevent negligent white light discharges in general and is the ultimate solution for nighttime use.

The One Hundred Concepts Lightcap also acts as a lens cover to keep carbon off your lens and clean when out training.

It’s a clever device that addresses a significant problem and provides signature reduction. Let’s unpack how this item functions and why it’s so impactful.

Key Takeaways

  • The One Hundred Concepts LightCap stops light from revealing your position at night.
  • It fits on weapon lights and costs $25 for basic models or $50 for rugged versions.
  • The cap comes in small (1.125”), medium (1.25”), and large (1.45”) sizes to fit most lights.
  • It’s made of tough UV-resistant plastic that lasts long and keeps lenses clean.

What is the One Hundred Concepts LightCap?

I’ve found an excellent tool for night operations — the One Hundred Concepts LightCap.

This $25 safety cap covers weapon light reflectors, preventing accidental flashes that could reveal your position.

Personally, I would recommend simply upgrading immediately to the ruggedized LightCap that comes with the Shock Collar — increasing the price to $50. I am not a fan of using just the shock cord and recommend running a Shock Collar for the application for LightCap use.

The One Hundred Concepts LightCap is a durable material that is American-made and ships quickly. The kit includes one cap, two shock cords, and a Ranger band. If you get the rugged version, it comes with a Shock Collar for easy installation and application.

The way it keeps me concealed while using my gear is impressive. The One Hundred Concepts LightCap blocks light reflection but allows me to use my weapon light when necessary. It’s easy to install and maintain.

For anyone prioritizing stealth and safety, this cap is an essential tool. Negligent white light discharges prevent you from staying low profile and unseen.

Key Features of the One Hundred Concepts LightCap

The One Hundred Concepts LightCap boasts key features that set it apart. It’s tough, light, and made to last in harsh conditions.

1.     Durable and rugged design

I’ve seen many light caps on Amazon, but the One Hundred Concepts LightCap stands out. Its tough TPU rubberized plastic makes it super strong. I’ve dropped mine a few times, and it still works great.

The design keeps dirt and dust out, too. This cap can withstand significant wear and tear while maintaining its functionality.

What I appreciate most is how it fits different lights. Whether you have a small or large light, there’s a One Hundred Concepts LightCap for you. At $25 for the basic model and $50 for the rugged version, it’s a wise investment.

But again, I highly recommend running a Shock Collar and simply upgrading to the rugged model right from the rip.

You’ll save money by not having to replace broken caps all the time, especially if you do any type of force-on-force training. Plus, it’s made in the USA, so you can expect high quality.

2.     Low-profile and lightweight

The One Hundred Concepts LightCap significantly improves weapon lights. Its low-profile design hides reflectors, keeping you hidden. At just a few ounces, it won’t weigh down your gear.

I’ve found it perfect for my AR setup.

This cap comes in three sizes to fit most lights. The small is 1.125 inches, medium 1.25 inches, and large 1.45 inches. It’s made of tough plastic that resists UV rays. You’ll barely notice it’s there, but it makes a substantial difference in stealth.

3.     UV-resistant thermoplastic material

I use UV-resistant thermoplastic for our One Hundred Concepts LightCap. This tough material stands up to sun damage. It won’t break down or fade over time. Our USA-made product lasts longer outdoors. The special plastic keeps its strength in harsh conditions.

It protects your gear from harmful rays. You can count on this durable cover to shield your light for years.

The One Hundred Concepts LightCap offers more than just light control. It keeps your lens clean, runs quiet, and is easy to use. Let’s check out some of the benefits!

1.     Keeps carbon off the lens

I really like my One Hundred Concepts LightCap for keeping my weapon light clean. It prevents carbon buildup on the lens. No more smudges or dirt blocking my view. I just snap it on, and my light stays clear, even after heavy use.

It’s a straightforward solution that makes a significant difference. I don’t worry about lens cleaning as much now. The cap does the work for me.

This UV-resistant cap is extremely durable. It handles the heat and grime from firing without issue. I’ve subjected it to some rigorous tests, and it holds up perfectly. The thermoplastic material is made to endure.

It reduces how often I need to clean my light. That means more time shooting and less time maintaining my gear.

2.     Silent operation for improved stealth

I’ve used LightCaps on my tactical lights for quite some time now. These caps significantly improve stealth. They prevent any light from leaking out when I don’t want it to. That means I can move around without giving away my position.

It’s like having an invisible cloak for my gear.

LightCaps also help me stay quiet. They don’t make any noise when I flip them on or off. This is crucial when I need to be silent. In high-stress situations, every little edge counts.

With these caps, I feel more confident in my ability to stay hidden and safe.

3.     Easy installation and user serviceability

The One Hundred Concepts LightCap is exceptionally easy to install and service. It attaches quickly to my weapon light without complications. The straightforward design allows me to clean or replace parts independently.

This eliminates the need to return it or seek assistance, saving time and ensuring my equipment remains operational.

The One Hundred Concepts LightCap’s uncomplicated design makes it effortless to use. Its built-in lever provides quick access to white light when necessary. It’s compatible with numerous weapon lights, offering versatility for my different configurations.

I can transfer it between firearms effortlessly, but it’s just easier to purchase one for each of your lights to set it and forget it.

Types of One Hundred Concepts LightCap Models

The One Hundred Concepts LightCap comes in different sizes to fit various weapon lights. You can choose from Small, Medium, Large, and Ruggedized versions for your specific needs.

LightCap™ Small

I’m fond of the One Hundred Concepts LightCap™ Small for my compact weapon lights (like my Inforce WMLx). It’s a durable little cap that prevents accidental light flashes. At just $25 or $50 for the rugged like I use, it’s a wise investment for any gun owner.

The cap fits tightly over the light’s head, preventing reflections that could reveal your position. It’s constructed from durable plastic that withstands UV rays and salt water. I’ve noticed it also keeps my lens clean, which is an added benefit.

LightCap™ Medium

I have tried the One Hundred Concepts LightCap™ Medium on my weapon lights. It fits most standard-sized lights perfectly, like the Streamlight TLR-1 HL that I run on some of my rifles.

This cap stops light from bouncing off the lens. That means no accidental flashes give away my position.

It’s tough, too — made from UV-resistant plastic that can take a beating.

The Medium size works great for many popular lights. It snaps on easily and stays put. I appreciate how it keeps carbon off my lens during firing. The low profile doesn’t get in the way either.

For stealth and protection, this cap is difficult to surpass. It’s essential for night ops or home defense setups.

LightCap™ Large

I’ve found the One Hundred Concepts LightCap™ Large to be highly effective for night operations. It fits perfectly on bigger weapon lights, blocking unwanted glare. The durable plastic keeps carbon off my lens and remains quiet during movement.

This cap is essential for preventing light slips downrange. It uses a ranger band to stay secure, even in challenging conditions. The UV-resistant material performs well outdoors. I can quickly attach and detach it, which is crucial when I need to switch between stealth and full light modes.

Ruggedized LightCap™ versions

I’ve got great news for you tough guys out there. The Ruggedized LightCap™ is here, and it’s a beast. This bad boy is made from TPU rubberized plastic with new textures for better grip.

It’s built to last and can take a beating. The best part? It’s silent when you use it.

For $50, you get the LightCap™ and a ShockCollar™. This combo stops those pesky white light slips that can give you away. It’s perfect for night ops or any time you need to stay hidden.

The new design is even better than the old one. It’s quiet, strong, and does its job without fuss. I use this version on all of my rifles.

Tips for Proper Installation of the One Hundred Concepts LightCap

Installing your One Hundred Concepts LightCap right is key. Place it correctly on your weapon light for best results. Make sure it fits well with your gear.

Below, we provide the full scoop on the proper setup, but I recommend checking out the LightCap install tutorial they published on their YouTube channel.

Positioning the One Hundred Concepts LightCap correctly

I always position my One Hundred Concepts LightCap with care. It’s crucial to tension it right on the weapon light bezel. This stops rattling during movement and prevents covers that pop. I make sure the integral lever faces outward for quick flipping.

Proper placement keeps the One Hundred Concepts LightCap secure yet easy to deploy fast when needed.

Getting the LightCap’s position spot-on matters. I line up the edges precisely with my light’s bezel rim. Then I apply even pressure all around as I push it on. This creates a snug, rattle-free fit that won’t budge.

But the flip lever still works smoothly for instant light access and allows the LightCap to be flipped to the side to completely clear the bezel (but it can be quickly placed back over the lens when needed).

Ensuring compatibility with weapon lights

I check my weapon light’s fit with the One Hundred Concepts LightCap before use. It’s key to get the right size — small, medium, or large. The cap must slide on snugly without force. Make sure the ranger band sits far back enough to clear the bezel when flipped.

Proper tension of the shock cord stops rattling. These steps ensure your One Hundred Concepts LightCap works well with your light setup.

For helmet lights or rail mounts, I pick the right LightCap model. The versatile design fits many systems. I adjust the cap’s position for a perfect seal. This blocks light leaks and keeps my gear stealthy.

With the right fit, my One Hundred Concepts LightCap prevents NDs and protects my lens from carbon buildup.
