While not your exact same scenario, I have used some 12v EL Ultra-Bright Wire (about 6' of it) a RC4 wireless dimmer. I had to write a custom profile to prevent some flickering when dimming, but it has worked for me perfectly for 6 months. Only issue I have is the power supply makes a small high pitched whine, but not noticeable from more than a few feet away. I know thats 12v and your looking for 120v, but my 2cents.
