Lighting options for jararrium? Any idea on some sleek lighting for a round jararrium? Outside of hanging sockets or a desk lamp.

I've heard of people using circular xenon/whatever led but can never find a proper one.

I want to light a jar in a shelf or something. I found a strip led that can screw into the shelf but something smaller that woukd light only the bowl/jar would be ideal.

Any suggestions are welcome. Thanks.
