Sorry if this is a stupid question, but my Google-fu has failed. Is it a LED designed to shine down through a hole in the PCB and out the bottom?
Here's an example:
Thanks in advance.

That's what the pdf data sheet at the link you included shows. See page 4.
That's exactly what they are.
Thanks guys. From what I can tell it's just a normal SMD LED that's upside down in the tape (which makes sense, since that's how a robot would need them for mounting).
I'm not sure why that warrants a separate product line instead of a different SKU but I'm sure they have their reasons...
"a normal SMD LED that's upside down in the tape "
I don't think so. Look at the solder pad on page 4 - says HOLE and shows the LED sticking down thru it.

That would put the pads on the wrong side. On a normal LED, the pads are on the opposite side of the substrate that the LED itself is on. On a reverse LED, the pads are on the same side.

For what it's worth -- attached are some pics of a normal Kingbright (e.g. non-reverse-mount) SMD LED I have from an earlier project; it's got equal sized pads on both top and bottom and they're connected. You're probably right that this isn't always the case but I just checked and all of the ones in my parts bin (Kingbright, Lite-On, a bunch of random China vendors) are this way.
