Copper PCB 20mm Tiple Nichia Optisolis

These are copper mcpcbs designed for use with Nichia Optisolis which are 95+ CRI emitters.   These are not true direct thermal path because the optisolis does not have a center heat pad.  Both pads are electrical.   however the boards do not have a crystal substrate layer so they are as close to direct thermal path as possible for this LED, and do perform very well.   These fit carclo 20mm optics but additional beam diffusion such as DC Fix is recommended to smooth out the beam.
