Here's my recent dilemma with LED's. And I'm glad this thread was started. I am 50/50 with Led. Sometimes they're awful and sometimes they're desperately needed. When I did my LOTR I wanted to keep the warm feel and give it my own look. I think LOTR is done well, but for some reason I just feel the mode/palantir/destroy ring shouldn't be white. Especially with the fellowship right below. It's also very hard to enjoy the lighting playing in the daytime. I felt orange/yellow would be the right angle. Unless my order was messed up CT orange and yellow are the exact same color. At least with frosted bulbs (I didn;t want my game too bright). I also wanted to make the game "good vs evil) red towards the right upper area and green towards the shire. It was almost working. No matter which way I go with LED's or incandescent bulbs it's either monotonous or a friggen bag of skittles. I think warm white is definitely the way to go in situations like this but I have a box of cool white bulbs and I don't want to spend $50 on another "test".
On the other side of the story. When I did WPT it made me feel like I didn't even play the game before. It's not only an improvement but seemed necessary. I think we should start a LED swap thread so we can trade colors and types when our "experiments" go wrong. Anyone want cool super brights for warm .
Basically in a newb type fo way I am finding out through experience that I agree exactly with what Frax said. On my STTNG there's white frosted cool bulbs in the GI and they pop into your peripheral and take away from the game.
