Here's a video of what it's doing. Pretty even amount of time in between flickers. I can't find any obvious loose connections. Vero 29 on pictured driver. This driver is not the one in the picture that I tried to order but with the OK from supra I held onto it. Thinking the driver is bad...these drivers run very warm. They are the warmest part of the fixture by far. Anyone seen this? Any advice?

I should note that yesterday I thought I noticed a very small flicker but it was so subtle I stood there for ten minutes trying to see it again but couldn't ever decide if I was seeing a flicker or not. Now I obvioulsy know it was a flicker

Here's a link to the driver I bought. The gold one pictured above is what arrived. I'm not sure the answer to your question. Are you asking for the Vf of the vero? Or what the driver can handle

I can see the specs on the side of the driver:) But I'm not familiar with the operating characteristics of the VERO, and I'm lazy and not feeling like reading the datasheet. To me, the flashing looks like some sort of fault protection on the driver, then it resets and repeats.

It's 36.8V I believe. Any suggestions for a new driver with the same specs to match the other one

I did a little searching, but I didn't see anything come up right away....sorry man...hopefully someone else can provide a link!

Bummer, looks like their replacement driver has a lower voltage range or maybe it is just a faulty driver. The silver one was good up to 42Vf and put out 2.25A. I have not tested those gold ones.

Driver options that will drive Vero 29 hard:

HLN-80H-42, 2.15A, dimmable, $40
NPF-90-42, 2.15A, $46
HLN-80H-36A, 2.55A, dimmable, $40
NPF-120-42, 2.9A, $56

I'm gonna send that seller a message and see if he'll replace it with a silver one. @SupraSPL did that driver get so warm because it was a pos or is it because of the high amperage? Wondering if a different driver can put out the same power but run cooler

The driver efficiency is probably 87-89%, judging by the gold 1.3A drivers. That is not terrible efficiency but even so it could be dissipating 10W of heat and would get quite warm/hot to the touch. The Mean Wells I mentioned above would be 90-91% efficient so they will get quite warm also.
