Heay, Rich. I didn't know you were planning on using an X-Boost driver with these diodes. Jordan told me that he has had a lot of complaints from people using X-Boost drivers with single mode diodes causing diode failures. He said he has never had this problem with multi-mode diodes, but the Nano-Boost driver was the answer to the X-Boost for single mode diodes. Just thought I'd give you a heads up.
