The HR-Line profile from Klus is an outdoor channel designed to be mounted directly into pathways, walkways, driveways and patios. Using a low profile water-resistant strip light with at least 3 LEDs per 1" you can create magnificent line of light LED fixtures with no visible dots or hot spots through the frosted cover. If sealed correctly this channel can achieve an IP67 rating for wet or damp environments. To seal the HR-ALU extrusion we recommend using DOW CORNING 3145 , transparent Neutral Silicone, see video link below for reference.
