Why we like these:

The Cloud Defensive Light Control System (or LCS) is one of our favorite products.  It's a simple design that creates a solid mounting solution for your Streamlight Protac pressure switch, rather than the flimsy plastic connectors that come with it.  The LCS also has channels that route the power cable to help keep everything organized and tight to the railing.  

While this does create a cleaner look on your rifle, we mainly prefer this because it protects the pressure switch.  The pressure switch for a lot of lights, but especially the Protac, can be a weak point in the lighting system.  The plastic can break or the cable can be damaged.  This is a great solution for strenghtening that weak point.  

We personally prefer the aluminum model, however the polymer model still does a great job at a lower cost and lighter weight. 


Official Description From Cloud Defensive:

The LCSmk2k is designed exclusively for the Streamlight ProTac series weaponlights Dual-Function tape switch that is commonly provided with the Streamlight ProTac series weaponlights. The LCSmk2k is TOO LONG for the shorter Streamlight 69132 switch provided with the TLR-series.


  • Unique Patent-Pending design utilizes a slot that ensures a snug, perfect friction-fit for the tape switch. Once installed its not coming out unless you want it to.
  • “Early Exit” feature allows the user to route the cable into the LCS and then exit the mount early if more cable slack is needed for your given setup.
  • 3-piece clamp design allows for perfect fit across all picatinny rails.
  • Proprietary Integrated Cable Channels (ICC) are integrated into both sides of the mount, giving the user the ability to control excess cable and making the mount ambidextrous and reversible. Channels can be used for other cable management as well (IR, et)
  • Full-length aluminum base allows for optimum tape switch engagement. No “give” in the tape switch when depressed makes for easier and more positive light engagement.
  • Shooter can fully use the entire length of the tape switch now.
  • The LCS Series Locks up 100% to your weapon. Zero movement. Zero play. Virtually indestructible.
  • Radiused/chamfered edges ensure comfort and ergonomic function.
  • Fully ambidextrous and reversible. The LCS be mounted in either direction, based on your preference/needs.

    Cloud Defense LCS

    Two snaps in a Z formation! As usual Panther City delivers the best gear, at an awesome price in the blink of an eye. The LCS does such an awesome job I bought another one. It is far superior to the Streamlight provided retaining clips at securing switch and excess cord management. Its an upgrade well worth the money and Panther City consistently has had the best price around.

    Good product. Locks down tape switch and wiring much better than what's included with the light. Panther City knocked it out of the park as usual with lighting fast shipping and stellar customer service.

    This is the go to for your protac tape switch. It’s a bit fiddly on install but locks very secure. I would 100% recommend this product to a friend. I also would recommend PCT to a friend. Fast shipping. Great packing and all around just friendly folks.
