Bulgarian Carrot - Hot or medium?

[WVTomatoMan]

Yes, there is a story behind this. The basic questions are as follows. Are Bulgarian Carrot peppers hot or medium hot? Are there two Bulgarian Carrots?

Here's the story...
I'm growing Ring of Fire peppers. F1 from seeds I purchased this year and F2 from seeds I saved last year. A guy at work wanted to grow some peppers and asked for leftover seedlings. I thought it might be good to have him grow one of the F2s because he grows in containers. I'm growing an F1 in containers. I had a couple of almost ripe peppers so I took them to work and left them on his keyboard. Later, as expected he IMed me and asked me about them. I told him about the F1/F2 situation and comparing the F1 peppers I brought to the F2 peppers he'd be growing. Here's basically how the rest of the IM went:
Him: Are they hot?
Me: Hot is a relative term.
Him: Am I going to die if I eat them?
Me: No you are not going to die.
Him: Come on, are they hot or not?
Me: Yes they are hot, but they aren't deadly.
Him: Okay I'm going to try.

So, he and his office mate gave them a try. I dropped by a short time later and his office mate informed me that he still could not feel his tongue. My buddy said they were really hot and that he had bought Habenaros at the grocery store that weren't as hot (which is probably true - grocery store hot peppers aren't very hot for the most part). After talking for a while they said in typical macho fashion that they could've taken it a little hotter. So they asked if I was growing anything hotter. I said that I know that the Jalapeno, Jaloro, and Tabasco peppers that I'm growing wouldn't be hotter. Then I went on to mention that I'm growing Bulgarian Carrot peppers and I had never grown them before and I didn't know if they'd be hotter or not. So we looked it up on the internet. The first site (complete with Scovile list) ranked it up there with Habenaro and Scotch Bonnet. The next site had it medium hot just above jalapeno. We looked at other sites with varying results. Any light that anyone could share would be greatly appreciated.

Thanks,
