There have been many posts on improving pinball playfield lighting by adding LED strips, etc.
I like to play my games in a brighter room and have just installed some adjustable LED ceiling fixtures.
I had to install them back away from the pinball machines, to avoid the lights reflecting on the pinball glass.
All I can say is, wow, what a difference they have made!
Below is a link to the fixtures I bought from Home Depot but, of course, they are available from many different places.
Thought I would share this as it may help others in a similar situation.
