...absolutely do not! I've recently replaced an outside security light with an LED unit. When off, the LEDs were showing some fluorescence.
When I checked the wiring with a multimeter, the live and neutral (identified by their colour) were in fact reversed. No problem with an incandescent fitting, but
Reversing the connections resolved the issue.
