Available in several colors, the low profile vcc Smb Series Fresnel round lenses provide even illumination for 3mm LEDs and fit into 0.171-Inch/4.3mm diameter mounting holes on 0.250-Inch centers. They feature a Fresnel design that improves light transmissibility and captures light more efficiently than a traditional lens, helping maximize visibility. Constructed from durable polycarbonate, these modular panel lenses minimize the Electrostatic discharge associated with traditional LED lens mounts while providing a wide viewing angle. These round lenses are RoHS and REACH compliant and free of conflict minerals.
