I am just beginning a remodel of a room to be used as my new train room. I am doing some experimenting with lighting. I am using all CFL bulbs in the fixtures. I started out with bulbs having a 6000K rating. These provided very white light throughout the room, much like daylight. But I found the fixtures much too harsh to look at. I have four sidewall lantern fixtures and two ceiling fixtures. The amount of light is adequate, and I am sure the quality of color reproduction would be fantastic on all the equipment I intend to use.
I don't plan any scenery or towns, just structures like bridges and trestles with tubular track and trains, all run conventionally. But, I digress from my intended purpose for this post. After deciding that the 6000K lighting was too harsh to look at, I opted for 2700K bulbs that offer a much warmer, gold or yellow glow. I don't imagine that color reproduction of the equipment will be as true, but the overall feeling of the room is warmer and more welcoming.
Now, the BIG question, what are you using for lighting? Does it matter, or do you even care about such things? Or, does this post even belong on this forum? In case anyone asks, all the fixtures all have translucent glass surrounding the bulbs, so the actual bulbs are not directly seen.
