Is it on a dimmer that is leaking current? *Some two wire dimmers
(like old X10) require a small voltage flow through the filiment at
all times. *X10 dimmers with a neutral connection dont have this
problem. *Otherwise some other wire is supplying current to the lamp
socket after the switch.


Likewise if its on a 2 wire timer that requires a filament for current
flow, that would cause the CFL to blink also.
