About 2 years ago I put LEDs in my Addams Family. I used Pinball Life's Ablaze Ghost Buster LEDs. On my cool white bulbs I noticed the 555 bulbs are starting to yellow just a bit, but the 44/47 are still cool white in color. You can really notice on the 3 white inserts on the left of the mansion. The bottom 2 are 555 and the top one is 44/47 bulb. Also you notice it in the greed inserts. Has anyone else noticed this on there machines? These bulbs are not the new premium bulbs he has just the plain ghost buster LEDs. Any ideas? Thanks for any info you might share.
