Retro warm whites are a good look for those that don't really like that bright look of LED's . I get mine through pinballbulbs.com. I find they are a bit weaker then most.. which I like a lot on older machines.. I know that is weird.. but the super brights and some other led's are just tooo bright for the game sometimes.. Plus.. they are a fair price and work well. They don't seem to have a built in resistor though.. so unless you upgrade your lamp driver board.. depending on game and year.. might get a bit of a flicker.
