Are there really no *small*, battery-operated LED lights (couple cm diameter, say) available, or am I just missing the correct search terms?

I need a few for my cabinet of curiosities and minerals collection (so a couple should be UV) but I literally can't find them anywhere...

Any help from #makers/#designers/random people in #askfedi is mightily appreciated (also boosts)
