Finding optics is a challenge because Vero29 is a relatively new product. I was able to get in touch with a Widegerm rep, Jenny Zou, (
[email protected]) who was willing to sell me their Vero29 specific reflector ~2$ plus shipping from China. They appeared to be willing to work with private individuals as they don't have any US based importers at the moment. The reflector was 11cm wide which took up too much of the panel's real estate.
The one in the photo above is a Ledil for BXRA RS LEDs but the LED diameter is very similar to Vero29 (29.2mm vs ~31mm). Interestingly, even though the Vero is slightly smaller, it's a pretty snug fit between reflector hole and LED itself. It looks like it's going to handle the work until the Ledils for Vero are more easily obtainable.
