Both neons and LEDs have the same problem - series ballast resistors. These
high value resistors with high voltage drop always drift high over time,
reducing the current and leaving the light dim. The solution? If you can
hack the fitting apart, replace the resistor. Pretty simple job really. I've
never found the neon or LED to have actually dropped in efficiency. It's
always the resistor.

I find that hard to believe. The part about the resistor(s)
drifting high, that is.

Do you have any hard data to support that hypothesis?
