A few things I don't understand

You mean MR16's
I see where you are coming from like the "17th edn boards" but I think everyone knows a "Type B,C or D Circuit Breaker to EN 60898" as an MCB. A majority of people call an RCCB an RCD, a fuselink a fuse etc.

Some MR16s are low voltage, but not all.

 

[Spark123]

Yep, the GU/GX5.3 ones usually operate at ELV.

 

[ban-all-sheds]

Yep, most of them operate at ELV.

Is that "most" as in "a significant majority", or as in "more than 50%"?

What are the sales figures for LV lamps with MR16 envelopes vs ELV? The shed shelves certainly seem stuffed full of them.

 

[Spark123]

What we usually call MR16 are the 12v flavour ones, the mains ones we tend to call GU10 (which is really the lamp base).

That is true.

But utterly illogical. There are some (rare) MR11 lamps with GU10 bases:

but the vast majority are MR16.

MR16 refers to the envelope, and has nothing to do with the base, you can get MR16 lamps with either a GU10 or a GX5.3 base:
