Good LEDs aren't any better than fluorescents in efficiency, but they deal with temperature swings better.
Also they don't have mercury in them.
A final advantage is the festive colored light show to be had from this Color Kinetics unit.http://colorkinetics.com
It's the "Lighttro" model available online for $20. There's a button on the side to change what pattern of colors it plays. Hey vendor- gimme free ones or I'll prostitute myself to your competition !! :)
Here's the fridge after and before changing the bulb. Actually it looks nothing like these pictures thanks to an automatic camera. But I'm happy cuz the bulb burns 2 watts versus 60 watts.
The fridge isn't as brightly lit as before, but that doesn't matter. The only reason for a fridge light is to remind you that your fridge is still working anyway.
