What purpose do these two pictured adapters serve and what are their proper names?Confuse, comfound and endanger people plus lighting systems.
Danger Will Robinson Male &
Danger Will Robinson Female
Which of the two left or right in the photo is more dangerous to people?

The one on the right, you could actually connect it to a cable from a PD, and then any splitters or controllers or opto-isos to protect said controllers would be fried.
Soundlight, is that more dangerous to people? (Not trying to nitpick, I honestly don't know the answer, but you seem to be referring to gear, where as Ship refers to health and safety.)

I'm gonna have to say that it is actually a NEMA L21-30R because if you look at the female side it looks like the smallest pin is opposite the "bent" one male side is indistinguishable.

as for charc's question about load. the NEMA L21-30R connector is rated at:
30 Amps, and 3 phase power with 120V on each leg.
I did find a note about it being specifically made for unbalanced loads on the legs.
If the cable is indeed 22 AWG DMX Cable, which I see no reason to question the ratings were actually a bit hard to find but the most constant comes from AMDJ and they rater there 5 pin DMX at 2.1 Amps per conductor @ 25 degrees C.
Obviously if for some reason you did use this thats is your weak point.
The one on the left is more dangerous to people, because they could touch the pins while it is live.
And i have no clue what they're for. I've see power adapters for powered speakers similar to this, but those wouldn't be 3-phase.
Visually they similar but if you look up the L20-30R you'll see it's for 347-600 VOLT 30 AMP 3 phase power. So you're looking at a TON more voltage going through the line, also if I had to venture a guess I'd say with the increased voltage and the lack of a ground pin I'd say you need loads on the legs that are a lot closer to being balanced. Someone will probably call me out on that but that's what my logical brain tells me is the case.
