Lighting for Display of a Reflection Hologram

[Blue Velvet]

We have a Lucy in a Tin Hat hologram that has been sitting in the dark for about a year now. It's finally time to light it and I want to be sure I do it correctly. I was planning on using a single mono point spotlight on our ceiling and aim it at the hologram at approximately 45 degrees. I've gathered that a 75w equivalent MR16 bulb with a GU10 base and a beam angle of 15-20 degrees would be ideal. But as I'm searching for fixtures and bulbs, I'm seeing all kinds of variables and don't want to order the wrong thing.

Could anyone here link me to a specific fixture and bulb that would work best for this? Happy to provide any measurements from the room or the hologram itself if that will help. Thanks in advance!
