Mission Impossible

We have some new lights in the other room, thought we'd get some LED bulbs. That is a LED but the main ones that came with are halogen

Light bulbs make me lose my temper at the best of times, but throw in some random alpha numeric codes, other apparently unassociated watts and volts and the buzz word 'dimmabke' and you end up in some sort of lighting hell of choices and options, NONE of which seem to match the info you have on the card that the bulbs came with.

There are some coming from eBay, I think it might be easier to sit in the dark for the rest of winter.
