I've noticed that the stores sell both regular (non-dimmable) and
Dimmable LED bulbs. The dimmable ones are more expensive. What is
different inside of them?


I've found that CREE dimmable LED bulbs work with Intermatic light
timers that pass a low voltage thru the bulb when the timer turns off.
These are in the wall timers that are marked incandescent only. Sure
there is a slight glow on the bulbs when they are off but it sure beats
digging up the driveway and front lawn to rewire the lamp post or spend
a hundred dollars on a new LED lamp post head.


What kind if timer is that? Whats the point of sending a low voltage to
the bulb other than to waste electricity?
The old mechanical timers simply turned off/on a switch. You must be
referring to a digital timer. But I still dont see the reason to send
that low voltage.

You should not need to dig the lawn up, just get a different timer. It
sounds to me that yours is defective.

Nope, not defective. They are 2 wire timers or switches - the current
to run the solid state timer is soursed through the bulb. No bulb, no
timer (or no remote switch)
