Ledil Mira Series Lenses for Cree were especially designed and optimized for the XLamp® MT-G and XLamp CXA15 series of Cree LEDs. These lenses were carefully designed to make light distribution as uniform as possible. They are all clear round lenses, offering viewing angles of 28º, 38º, and 58º. They are made of optical grade PC material with high UV and temperature resistance, allowing for the use of high current and temperature conditions. The lenses should be fastened to a heat sink with a PU foam adhesive tape of automotive grade, or fastened with appropriate, Ledil-recommended adhesive.
