Description
Lights only work well when their lenses are clean. CLENS provides an easy way to protect lenses during extended shooting sessions. Just like goggle tear-offs for off-road riding, just remove the dirty CLENS to return your light to its optimal brightness
CLENS (pronounced “cleanse”) is a set of heat-resistant clear polymer circles that are cut to fit on a wide range of flashlight and weapon-light lenses. CLENS protects the lens from carbon and other debris that can build up from the use of lights during firearms training. CLENS can be removed to quickly clean a light, rather than having to apply Vaseline before shooting, replace a lens, or risk abrasion with lens cleaners.
Below is a CLENS size chart, showing the four models of CLENS sheets and the corresponding count and sizes of CLENS on each sheet.

CLENS’ mild adhesive backing has a higher affinity for polymer than glass. This makes it easy to attach and position, without leaving adhesive on clean glass. However, adhesive may stick to a dirty or damaged lens; in this case, touching the sticky side of CLENS to any residual adhesive should remove it from the lens.
CLENS was made in collaboration with Aaron Cowan of Sage Dynamics / Sage Instruments.
* Follow all firearm safety rules at all times. Detach lights from firearms prior to installing, removing, cleaning, or replacing the CLENS.
Designed and manufactured in the USA.

These really do work as advertised. Prevents carbon build up and peels right off.
My only complaint is that they are super size specific for it to work. I tried using these on a light whose bezel was smaller than the X300 and it didn’t stick on well at all and peeled off on it’s own.

Got these for convenience vs. having to manually clean lenses al the time. Definitely better than potentially scratching expensive glass with abrasives. Application is easy and I’m impressed with them so far.
