High-Efficiency 10W LED Lenses ams OSRAM High-Efficiency 10W LED Lenses provide an efficient and highly uniform smooth light gradient which eliminates hot spots and rings for illumination applications. These high-efficiency 10W LED Lenses are available in three viewing angles--12º Narrow Spot beam, 23° Narrow Flood beam, and 37° Flood beam. Designed specifically for the 10W single color emitter series, these lenses are made of optical grade PMMA material which allows for use of high current and temperature conditions. Included holder fastens to the PCB with appropriate adhesives, such as epoxy or polyurethane-based, and are compatible with ams OSRAM standard MCPCB assemblies.
