Underscore15 is a technological combination of a frontal emission strip with a cover or sheath to protect the LEDs and a slim aluminium profile. Underscore15 is a system designed with two different usage options. Either a Ledstrip or a Ledstrip Tube can be fitted on the aluminium profile. The version with a Ledstrip is covered by a layer of polyurethane. This material reduces the risk of the strip being broken and maintains the LEDs in perfect condition by protecting them from contact. Ledstrip Tube, with its silicone sheath, also protects the strips by reducing stress that could lead to tears. Both parts, the strip and the sheath, are extremely easy to replace.
