I am experimenting with mine. It came with a partial Cointaker kit in it. Cool white mostly. Cool blues etc.
I had some Comet LEDs lying around so I started to experiment. I might prefer warm white for this game. In fact, I think I prefer warm white, frosted lens for all my games.
(please note, Comet makes a distinction between warm, natural and cool white)
Back of game is Comet Warm White. Front of game is Cointaker cool white.
Here are some pics.
