Sorry for the misunderstanding, I meant 4-5k SHU. But thats just a wild guess considering that Hungarian hot peppers usually score around 2-3k and these haveĀ significantly, but not a whole lotĀ more heat.
Anyways, thank you for the suggestions Yellow Bedder could be possible, it looks quite similar. On the other hand its quite smaller than Cayenne and growing upside down.
