I put in a CFL and it has survived many months now, but it is dim and takes a long time to reach full brightness especially in the cold months (in Maine that is all months except July).


Vibration on light bulb is place for Rough Service bulbs...same as used in your hand light...difference is better support of the fragile tungsten filament.

LED's are not temp sensitive or vibration sensitive.

Vibration is not an issue for led...

Well i wouldn't say not a issue. Since the tree huggers don't want anybody using lead for soldering, the new stuff has a set of problems of it's own. You are gonna see more bad solder joints and that leads to failures. Crappy solder joints don't like vibration. Also, if the led house lights are anything like the led christmas lights, good luck. They seem to use iron or steel leads ,not lead or tin plated leads. This causes rust, anyone who has led lights outside can attest to that. I can see them rusting in the outdoor sockets and breaking off when you try to remove them.

All true for old style LEDs

More and more the LEDs used today are "surface mount" ... Not so many any more are "through hole mount"

No steel leads to corrode when used outside, and surface mount soldered is how most all electronics is assembled today.

I'm talking about the leads, not about the die. You won't see copper leads,
too expensive.
