What are the pros and cons of LED vs CFL vs incandescent bulbs for outdoor lighting?
The short answer is to check with the bulb manufacturer. Ambient temperature and use case requirements may also be mentioned on the box/packaging.  

The long answer is that it depends (as always eh?). From what I could find online, CFLs and incandescent bulbs are actually MORE sensitive to LOW temperatures than LEDs. So in your specific use case, I would think you would be fine in using an LED bulb. 

That being said, keep in mind that there ARE certain environments where LEDs may perform worse -- particularly in settings where the ambient temperature is very high, resulting in overheating of the LED package and eventually leading to device failure. I think most manufacturers are getting better at heat sink designs anyway so this may not be a concern later.
