I've never damaged a LED by *trying* it on a non trailing edge

then you've not used a CR PSU led light for that job.
How would I know a CR PSU from an LED that simply says 'dimmable' (with a
suitable dimmer) ?
Dimmable LEDs can not contain CR PSUs, they don't survive chopper dimming.
The only way to tell a CR PSU LED from an SMPSU LED is to open it up.
Thats bull****, you can measure it too.
