The certified polycarbonate HS outdoor rated frosted cover for our KL1 type extrusions is designed to be used in both indoor and outdoor environments and can withstand high temperatures up to 120C/ 248F. Double sided UV protection creates a high resistance to long term weathering and the milky frosted cover creates good light dispersion with approximately 70% light output depending on the depth of the profile used. The HS cover is flatter and less bendable than our K type indoor covers and is recommended for settings with high vibration due to its tight fit in the extrusion. With proper sealing techniques using a neutral, non conductive silicon you can achieve an IP67 waterproof rating. Using a strip light with a minimum of 140 LEDs per meter you can achieve a line of light effect with no visible dots or hot spots. This cover is available in 1M, 2M and 3M lengths.
