The KLUS clear cover K 12 for our KL2 sized channels allows for maximum light output while protecting the LED strip lights and wiring beneath. The grooves of the polycarbonate cover and aluminum channel allow you to easily push and mate the cover into place. The clear cover K 12 allows for 100% light output and is ideal for concealed lighting applications where the aluminum channel will be hidden or out of eye sight. For less hot spots and more of a concealed look you may consider our different frosted cover options. This cover is intended for indoor use only and is not UV resistant. For UV protection or use in damp environments use our outdoor rated HS12 cover options. This product is available in 1M and 2M lengths.
