I have two of these switches controlling a light post and two outdoor sconces. Both work great with CFLs or incandescents.The post light has an LED that stays glowing when it is switched off. Do I need a LUT-MLC even though the switch is connected to a neutral wire?The sconces seem to work with the LEDs for a few power cycles and then stop working. At that point you can only get them to light up if you fiddle with unscrewing the bulb. Any thoughts on what might be causing that?Thanks for your help.
